Sako TRG#History

File:Valmet m86 sniper.jpg

Even though the TRG-21 obtained its origins from the successful Sako TR-6 target rifle and 1984–1986 development work for the hardly produced Valmet Sniper M86 rifle by the former Finnish state firearms company Valmet which merged with Sako, the {{convert|4.7|kg|lboz|abbr=on}} TRG-21 was designed as a result of a thorough study of sniper requirements.{{cite book |last=Hyytinen |first=Timo |year=2001 |title=Asesuunnittelua Suomessa |language=fi |publisher=Arma Fennica Oy |pages=142–144 |isbn=978-951-97543-3-8}}

In 1989 Sako Ltd. (Riihimäki, Finland) introduced the TRG-21 precision rifle as a sniper rifle model chambered in .308 Winchester. With the introduction of the TRG bolt-action, Sako moved away from the modified two-lug Mauser bolt-actions, favoured during the past, to an action with a symmetrical three-lug bolt of {{convert|19|mm|in|2|abbr=on}} diameter, displaying a locking surface of {{convert|75|mm2|in2|abbr=on}}. The TRG-21 action was designed for a maximum cartridge length of {{convert|75|mm|in|2|abbr=on}}. The evolution of this design continues to the present and can be found in Sako's hunting rifle offerings, the Sako 75 and the Sako 85. Subsequently, a second precision/sniper rifle with a {{convert|20|mm|in|2|abbr=on}} longer scaled up magnum action emerged as the TRG-41 in order to take advantage of the .338 Lapua Magnum cartridge.

A more hunting oriented variation of the TRG was introduced in 1992 as the TRG-S M995 and TRG-S M995 Magnum, which both use the same scaled up magnum action and bolt (different bolt handle) as the TRG-41 with the exception that the receiver is open at the top with an integral Sako-type wedged dovetail rail rather than possessing a cartridge ejection port on the right side and a parallel {{convert|17|mm|in|2|abbr=on}} integral dovetail rail as found with the TRG-41. The TRG-S M995 (Magnum) was produced until 2003 and chambered in eight standard chamberings and fourteen magnum chamberings, including .338 Lapua Magnum. All TRG-S M995 rifles utilized the same stock and receiver designed for a maximum cartridge length of {{convert|95|mm|in|2|abbr=on}}. Four different sized detachable box magazines and three different bolt bodies were used to accommodate the dimensionally different rifle cartridges offered.{{Cite web |url=https://www.sako.fi/sites/default/files/SakoTRG-S.pdf |title=SAKO TRG-S RH manual|access-date=2020-08-15 }} A carbine variant of the TRG-S was also produced that according to Sako literature featured a {{convert|520|mm|in|1|abbr=on}} long barrel. However, M995 carbines imported to the United States featured a {{convert|495|mm|in|1|abbr=on}} barrel and were chambered in .375 H&H Magnum only. Sako planned to produce a short action TRG-S M975 designed for a maximum cartridge length of {{convert|75|mm|in|2|abbr=on}}, that would have been based on the TRG-21. In the end Sako abandoned this plan and only a handful of M975 prototypes were produced.{{Cite web|title=TRG-S/M995 action size|url=https://sakocollectors.com/forum/threads/trg-s-m995-action-size.15194/|access-date=2020-08-18|website=Sako Collectors Club Discussion Forum|date=8 May 2020 |language=en-US}}

To make the TRG system more suitable for military use, Sako upgraded and improved the TRG-21/41 design in the late 1990s. Some TRG accessories like the muzzle brake and bipod (that lets the rifle swivel or "hang" near its bore axis offering a more stable shooting position with large and heavy aiming optics mounted) were also improved. This resulted in the TRG-22/42 rifle system introduced in 1999.

In June 2007 a voluntary factory recall concerning TRG-22, TRG-42 and M995 (TRG-S) rifles manufactured between October 1999 and October 2002 was put out to correct the possibility that a portion of the firing pin could exit rearwards when firing a defective cartridge.{{Cite web|title=Safety Gate: Rapid Alert System for dangerous non-food products - Weekly Report — Alert number: 0567/07|url=https://ec.europa.eu/consumers/consumers_safety/safety_products/rapex/alerts/?event=main.weeklyOverview&web_report_id=228&lng=en|access-date=2020-08-21|website=European Commission - Safety Gate: Weekly overview report|language=en}}

Around 2011 an American Sako vendor commissioned a special limited production run of TRG-22 sniper rifles chambered in .260 Remington cartridge and started offering them as of May 2011.{{Cite web |url=http://bulletin.accurateshooter.com/2011/07/eurooptics-super-deal-on-sako-trg42-in-338-lapua-magnum/ |title=EuroOptic Exclusive: .260 Remington TRG22s at www.accurateshooter.com |access-date=2011-07-23 |archive-url=https://web.archive.org/web/20111004115442/http://bulletin.accurateshooter.com/2011/07/eurooptics-super-deal-on-sako-trg42-in-338-lapua-magnum/ |archive-date=2011-10-04 |url-status=live }}

In 2013 the TRG system was further upgraded and improved based on customer requirements. The upgrades consist of mounting improved recoil pads to reduce felt recoil, a newly constructed bolt release and a new fully adjustable two-stage trigger mechanism that features a new more ergonomic ambidextrous safety lever, and a trigger guard milled from aluminium for more positive magazine attachment. Further the bolt handle and its attachment to the bolt body were ruggedised. These general 2013 upgrades are backwards compatible with older TRG sniper rifles. Exclusive for the .338 Lapua Magnum chambered TRG-42 model a new bolt featuring double plunger ejectors was introduced in 2013 to improve the ejection reliability of dimensionally large and heavy .338 Lapua Magnum rifle cases.{{Cite web|url=http://www.sako.fi/sakotrg_upgrade.php|archive-url=https://web.archive.org/web/20140512231117/http://www.sako.fi/sakotrg_upgrade.php |url-status=dead |title=SAKO TRG 22/42 UPGRADE|archive-date=May 12, 2014}}

In 2018 Sako introduced the TRG-22 A1 and TRG-42 A1 models. The TRG A1 models have a Sako TRG M10 Sniper Weapon System alike stock, featuring an aluminium middle chassis frame, side-folding quick adjustable buttstock, and a fore-end with the M-LOK rail interface system that allows for direct accessory attachment onto "negative space" (hollow slot) mounting points.{{Cite web |url=http://www.sako.fi/en-us/rifles/sako-trg/trg-2242-a1 |title=TRG 22/42 A1 |date=9 January 2018 |access-date=2018-02-06 |archive-url=https://web.archive.org/web/20180207063048/http://www.sako.fi/en-us/rifles/sako-trg/trg-2242-a1 |archive-date=2018-02-07 |url-status=live }} The chassis frame is offered in Tungsten Gray, Olive Drab Green, Graphite Black and Coyote Brown Cerakote (a thin surface coating containing ceramic particles) finishes. The top of the receiver was designed with a built-in 30-MOA Picatinny rail. The fore-end contains a small toolbox that can be accessed with the bolt knob. It contains Torx 25, 15 and 10 head tools to facilitate field adjustments and maintenance. The TRG A1 models do not offer the user configurable multi calibre modular system of the Sako TRG M10 Sniper Weapon System. The bolts of the TRG A1 models all feature double plunger ejectors introduced earlier for the .338 Lapua Magnum TRG-42 and the TRG-22 A1 model expands the chambering palette with 6.5mm Creedmoor.{{Cite web |url=http://www.thefirearmblog.com/blog/2018/01/26/shot-2018-sakos-new-trg22-a1-6-5-creedmoor-victrix-armament-sniper-rifles-beretta-defense/ |title=SHOT 2018 SAKO's new TRG22 A1 in 6.5 Creedmoor and VICTRIX Armament Sniper Rifles at Beretta Defense |date=26 January 2018 |access-date=2018-02-06 |archive-url=https://web.archive.org/web/20180207062955/http://www.thefirearmblog.com/blog/2018/01/26/shot-2018-sakos-new-trg22-a1-6-5-creedmoor-victrix-armament-sniper-rifles-beretta-defense/ |archive-date=2018-02-07 |url-status=live }}[https://media.sako.global/image/upload/v1691732877/TRG_22_42_A1_instruction_manual_v1.9_gc6vrx.pdf TRG 22 A1 TRG 42 A1INSTRUCTION MANUAL]

In 2024 the TRG-62 A1 was added to the A1 range as the third and largest iteration, as its action was designed for a maximum cartridge length of well over {{convert|95|mm|in|2|abbr=on}}. The up to {{convert|113.40|mm|in|2|abbr=on}} long .375 CheyTac (9.5×77mm) cartridge was selected and introduced to the TRG range to extend the achievable effective range up to {{convert|2000|m|yd|0|abbr=on}}, without having to deal with substantial bolt thrust or breech pressure increase related drawbacks.{{Cite web |url=https://bobp.cip-bobp.org/uploads/tdcc/tab-i/375-chey-tac-170627-en.pdf |title=C.I.P.

The muzzle brake was revised to a four-chamber set up for the new dimensionally larger and more powerful 9.5×77mm chambering. The top of the receiver was revised to a built-in 30-MOA or 45-MOA NATO Accessory Rail and the fore-end contains a small toolbox containing Torx 25, 15 and 10 head tools to facilitate field adjustments and maintenance. It is marketed for "military and law enforcement only".{{Cite web |last=Valpolini |first=Paolo |date=2024-06-07 |title=The Sako TRG 62 A1: The evolution of long-range precision in military equipment is being introduced |url=https://www.edrmagazine.eu/the-sako-trg-62-a1-the-evolution-of-long-range-precision-in-military-equipment-is-being-introduced |access-date=2024-06-07 |website=EDR Magazine |language=en-GB}}{{Cite web |last= |first= |date=2024-06-18 |title=Sako TRG 62 A1 |url=https://www.sako.global/rifle/sako-trg-62-a1-b2b |access-date=2024-06-18 |website=Sako |language=en-GB}}

A future TRG-62 A1 variant chambered for the up to {{convert|115.50|mm|in|2|abbr=on}} long .408 CheyTac (10.36×77mm) cartridge is under development.{{Cite web |last= |first= |title=Eurosatory 2024: Sako showcases the TRG 62 A1 long-range rifle |url=https://www.janes.com/osint-insights/defence-news/industry/eurosatory-2024-sako-showcases-the-trg-62-a1-long-range-rifle |date=2024-06-18 |website=Janes |language=en-GB}}

Sako never totally forgot the target rifle origins of the TRG system. The necessary accessories to attach sighting components such as match grade peep sights or target aperture sights and a mirage strap are all available. Equipped with these accessories the TRG can be used for non military or law enforcement tasks such as 300 m UIT standard rifle competition, CISM competition or other kinds of full bore target shooting. The rifle is commonly seen in long-range competition where it has done very well.{{Cite web |url=http://www.6mmbr.com/gunweek069.html |title=accurateshooter.com: Gun of the Week Collection, Week 69, TRG-22 for Competition - the Dutch Perspective by Jim de Kort |access-date=2007-05-24 |archive-url=https://web.archive.org/web/20070128203548/http://www.6mmbr.com/gunweek069.html |archive-date=2007-01-28 |url-status=live }} Besides civilian target shooting the TRG system can and is sometimes used for hunting.

The TRG system's purposive design features, reliability in adverse conditions and consistent accuracy performance (a capable marksman can expect ≤ 0.5 MOA consistent accuracy with appropriate ammunition) have made it a popular, though expensive, sniper rifle system.A standard factory TRG-42 .338 Lapua Magnum user from Finland has reported on successfully hitting {{convert|45|×|90|cm|in|abbr=on}} reactive army targets from {{convert|1600|, |1800|and|2008|m|yd|0|abbr=on}} before a group of witnesses. The shooting area air density ρ was 1.228 kg/m³. This is slightly denser than International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m³). Besides the rifle, ammunition (in this case handloads with GB488 16.2 g (250 gr) Scenar projectiles) and skill of the marksman, the employed sighting components, fire control software calculations and favourable atmospeheric conditions are also important to hit point targets at those ranges.

The TRG system is almost unique in being a purpose-designed sniper rifle, rather than an accurised version of an existing, general-purpose rifle.{{citation needed|date=June 2015}} The sniper rifles can have a matte or manganese phosphatised finish.

The heart of the TRG system is a cold-hammer forged receiver and barrel. Both provide maximum strength for minimum weight as well as excellent resistance to wear. The action has a hex style profile on top with a smaller closed ejection port. Actions with an ejection port make it more difficult to reach in with a finger to discreetly eject brass when desired, but it does allow for additional strength in the action. The "resistance free" bolt has three massive lugs and requires a 60-degree bolt rotation and a {{convert|98|mm|in|2|abbr=on}} bolt throw for the short and {{convert|118|mm|in|2|abbr=on}} bolt throw for the long bolt-action; these features should be appreciated by the shooter during multiple firings that require rapid projectile placement on the target. The bolt handle is the appropriate length and sports a large synthetic bulbous knob that provides a firm, positive grip. On top of the receiver a {{convert|17|mm|in|2|abbr=on}} integral dovetail rail with shape connection drillings for one or more recoil lugs provides for fixing mounting components to accommodate different types of optical or electro-optical sights. Folding iron sights can be obtained for secondary or emergency use.{{Cite web|url=http://www.sako.fi/pdf/manuals/TRG22_42.pdf|archive-url=https://web.archive.org/web/20070819194908/http://www.sako.fi/pdf/manuals/TRG22_42.pdf |url-status=dead |title=Owner's and maintenance manual for the SAKO TRG-22/42 sharpshooting system|archive-date=August 19, 2007}}

The receiver's large bedding surface is mated to an aluminium alloy-bedding block by three screws for maximum stability. This combination ensures an unusually high degree of stability.

The detachable box magazine is based upon centre feeding for maximum reliability as well as precise positioning of the cartridge into the chamber. Alternatively cartridges can be loaded singly directly into the chamber.

The free-floating, heavy, chrome moly barrels (chrome moly barrels resist throat erosion better offering a longer accuracy life than stainless steel barrelsThe Finnish Army found out during a test/trails program and 7 years of actual service that the barrels of their Sako TRG-42's lasted 4000 to 5000 rounds with Lapua Lock Base B408 factory ammunition before showing impermissible accuracy decay. The Finnish Army consistent accuracy requirement for these rifles is ≤ 1 MOA at 1000 m. If this requirement is not met the TRG-42 gets a new .338 Lapua Magnum barrel. This is normal practice for active high performance precision rifle operators who regard barrels as expendable items. The continuous use of very powerful handloads (which results in higher muzzle velocities) resulted in much quicker throat erosion reducing the TRG-42 barrels accuracy life to 1000 to 2000 rounds.) for the available cartridge chamberings all have a different length, groove cutting and rifling twist rate optimised for their respective chambering and intended ammunition. The .260 Remington, .308 Winchester, .300 Winchester Magnum and .338 Lapua Magnum chamberings are available with barrels of common length for sniper rifles and relatively short {{convert|510|mm|in|2|abbr=on}} long barrels. On special order TRG sniper rifles can also be supplied with stainless steel barrels. Two types of flash eliminator/muzzle brakes are available as an accessory with one being threaded to accommodate a sound-suppressor.

For the .260 Remington chambering a non-traditional 203 mm (1 in 8 inch) or 31.2 calibres right-hand twist rate optimised to stabilise longer, heavier very-low-drag bullets was selected over the standard 229 mm (1 in 9 inch) or 35.2 calibres twist rate. The TRG-22 can be ordered cambered for the .260 Remington cartridge as of May 2011.{{Cite web |url=http://www.eurooptic.com/sako-trg-22-rifles.aspx |title=Sako TRG-22 260 Remington is now available, May 2011 |access-date=2011-05-16 |archive-url=https://web.archive.org/web/20110624085622/http://www.eurooptic.com/sako-trg-22-rifles.aspx |archive-date=2011-06-24 |url-status=live }} The introduction of the .260 Remington (6.5×51mm) chambering does not introduce major technical changes for the TRG system since the .260 Remington is essentially a necked down 6.5 mm (.264 in) variant of the .308 Winchester (7.62×51mm) cartridge, meaning these cartridges can be used in .308 Winchester chambered rifles only requiring different barrels.{{Cn|date=March 2025}}

The 6.5 Creedmoor chambering has the traditional 203 mm (1 in 8 inch) or 31.2 calibres right-hand twist rate shares the relative ease of chambering it in arms designed for .308 Winchester sized cartridges, though the 6.5 Creedmoor (6.5×49mm) maximal overall length is {{convert|0.64|mm|in|3|abbr=on}} longer compared to the .308 Winchester.{{Cn|date=March 2025}}

For the .308 Winchester chambering the 280 mm (1 in 11 inch) or 36.7 calibres right-hand twist rate with four grooves was selected over the 305 mm (1 in 12 inch) or 40 calibres, traditionally found for the .308 Winchester, as a compromise when switching between supersonic and subsonic cartridges.

The .300 Winchester Magnum chambering also has a non-traditional 280 mm (1 in 11 inch) or 36.7 calibres right-hand twist rate. Due to the .300 Winchester Magnum cartridge dimensions it is a long TRG-41/TRG-42 bolt-action chambering.

For the .338 Lapua Magnum chambering a non-traditional 305 mm (1 in 12 inch) or 36.4 calibres right-hand twist rate was selected to optimise the rifle for firing 16.2 gram (250 grain) .338-calibre very-low-drag bullets. As of 2009 .338 Lapua Magnum barrels can also be supplied with a 254 mm (1 in 10 inch) or 30.3 calibres twist rate optimised to stabilise longer, heavier very-low-drag bullets like the Sierra HPBT MatchKing and Lapua Scenar .338-calibre 19.44 gram (300 grain) bullets. The traditional 254 mm (1 in 10 inch) has since become the standard twist rate for the .338 Lapua Magnum chambering. Due to the .338 Lapua Magnum cartridge dimensions it is a long TRG-41/TRG-42 bolt-action chambering.

The two-stage trigger mechanism displays an adjustable trigger pull weight of {{convert|1|to|2.5|kgf|lbf|abbr=on}} and can be adjusted for length, horizontal and vertical pitch. The advantage of these features is to prevent trigger movement in an inappropriate direction that would cause the rifle to move off target. Trigger travel is short with no noticeable over-travel. The trigger mechanism can be removed without additional disassembling of the rifle. The firing pin travel is {{convert|6.5|mm|in|2|abbr=on}}. The trigger guard is dimensioned to allow easy access with gloved fingers.

The safety lever is located in front of the trigger inside of the trigger guard and can be operated without producing mechanical noise. The two-position safety locks the trigger mechanism, locks the bolt in closed position and blocks the firing pin. The safety is on when it is in its rearmost position. It is off when it is pushed to its most forward position. When the weapon is cocked the firing pin protrudes {{convert|1.6|mm|in|2|abbr=on}} from the rear of the bolt-action, making it possible to feel if the weapon is ready to fire or not in poor visibility.

File:Sako TRG folding stock + Zeiss 3-12x56 SSG P.JPG

The TRG stock design is besides sniping requirements, designed to conform to both UIT and CISM regulations. Sako offers black, green, desert tan or dark earth coloured stock variants and the green, desert tan or dark earth stock variants are {{convert|0.2|kg|lb|1|abbr=on}} heavier than the black variants. In 2011 Sako also began offering stocks in several styles of digital camouflage. The base of the ergonomic injection-moulded polyurethane forestock is made of aluminium and encompasses the bedding block with the bedding block serving as a point of attachment for a bipod. The polyurethane buttstock with its pistol grip and integrated aluminium skeleton to add strength, is designed for right- and left-handed shooters. The rear of the buttstock possesses a series of spacer and angle plates to regulate the length of pull and curvature adjustments that can be tailored for the individual shooter. The buttplate is adjustable for both height and pitch. Finally, the cheek-piece is adjustable for both height and pitch as well.File:Sako TRG-42 2.jpg

The stock features two steel sling swivel attachment sockets positioned at the right and left rear sides of the buttstock. Forward sling attachment is achieved by inserting and fixing a metal sling mount into a metal rail which runs under the forestock or forend. This forward sling attachment point can be (re)positioned along the length of the rail for right- or left-handed use and is fixed with a screw. The factory carrying/shooting sling itself features quick mountable and detachable metal swivels. The swivels are mounted by pushing them into an attachment socket and detached by pushing integrated buttons in the swivels and pulling them out of the attachment sockets.

A folding skeleton type buttstock designed for right- and left-handed shooters is also available. The folding stock is {{convert|0.5|kg|lb|1|abbr=on}} heavier than the non-folding green, desert tan or dark earth stock variants and is hinged behind the pistol grip; it folds to the left side and locks into position. When folded, the rifle becomes {{convert|250|mm|in|2|abbr=on}} shorter. The steel parts of the folding stock are manganese phosphatised and the polyurethane parts are coloured olive drab or desert tan. The rear of the buttstock is adjustable for length of pull and height. The cheek-piece and rear support are also adjustable for height. These adjustment options allow shooters of various sizes and shapes to tailor the TRG folding stock to their personal preferences, which is an uncommon feature for folding stocks. The pistol grip body has a steel loop for a hook type military sling swivel. Sako TRG folding stock rifles are supplied with a Picatinny rail for mounting aiming optics.{{Cite web|url=http://www.sako.fi/pdf/specs/TRG_FoldingStock.pdf|archive-url=https://web.archive.org/web/20081209233225/http://www.sako.fi/pdf/specs/TRG_FoldingStock.pdf |url-status=dead |title=SAKO TRG folding stock specification|archive-date=December 9, 2008}}

The folding stock was later redesigned with the most conspicuous change being a bigger "foot" with an external lever/hinge support system monopod instead of the vertical moving small "spike" found on the earlier folding stock.

Several versions of TRG-specific bipods were produced that all lock into an attachment point in the aluminium bedding block at the end of the forestock. The latest bipod version is one of a few rifle bipods that lets the rifle swivel or "hang" just above its bore axis offering a more stable shooting position with large and heavy aiming optics mounted. It has a narrower leg angle due to complaints that the previous version interfered with some night vision systems mounted forward of the telescopic sight. Further versions of accessories are the ITRS tri-rail NV attachment point with an optional extended aluminium bedding block. This extended bedding block also can feature an optional STANAG 2324 Picatinny rail in the bottom of the block.

The Sako TRG M10 Sniper Weapon System was unveiled by Sako in October 2011.{{Cite web |url=http://www.sako.fi/rifles/sako-trg/trg-m10 |title=SAKO TRG M10 |date=9 January 2015 |access-date=2016-01-11 |archive-url=https://web.archive.org/web/20150124051309/http://www.sako.fi/rifles/sako-trg/trg-m10 |archive-date=2015-01-24 |url-status=live }} It was designed as a user configurable modular system and does not share its receiver and other technical features with the preceding models in the Sako TRG line. It can switch between .308 Winchester (7.62×51mm NATO), .300 Winchester Magnum and .338 Lapua Magnum chamberings by changing the bolts, magazines, forends and barrels, to adapt to various requirements in the field. When it was first introduced, it was marketed for "military and law enforcement only".{{Cite web |url=http://bulletin.accurateshooter.com/2011/09/sako-introduces-trg-m10-new-modular-tactical-rifle/ |title=SAKO Introduces TRG M10 — New Modular Tactical Rifle |access-date=2011-09-20 |archive-url=https://web.archive.org/web/20111003134729/http://bulletin.accurateshooter.com/2011/09/sako-introduces-trg-m10-new-modular-tactical-rifle/ |archive-date=2011-10-03 |url-status=live }}{{Cite web |url=http://accurateshooter.net/Blog/trgm1007.jpg |title=SAKO TRG M10 standard weapon configuration chart |access-date=2011-09-21 |archive-url=https://web.archive.org/web/20111213070252/http://accurateshooter.net/Blog/trgm1007.jpg |archive-date=2011-12-13 |url-status=live }}

It was entered as a contender for the Precision Sniper Rifle program by the United States Special Operations Command to replace all current bolt-action sniper rifles in use by U.S. special operations snipers with a single bolt-action rifle chambered for a large calibre magnum chambering. The contract was awarded to Remington Arms for their Modular Sniper Rifle winning against the TRG M10 in 2013.{{cite web|url=http://militarytimes.com/blogs/gearscout/2013/03/07/socom-psr-awarded-to-remington-msr/|title=SOCOM PSR contract awarded to Remington Defense MSR|last=Curtis|first=Rob|date=7 March 2013|publisher=Military Times|work=Gearscout blog|access-date=9 March 2013|archive-url=https://web.archive.org/web/20130314035125/http://militarytimes.com/blogs/gearscout/2013/03/07/socom-psr-awarded-to-remington-msr/|archive-date=14 March 2013|url-status=live}}

The TRG M10 is a manually operated bolt action sniper rifle that uses a rotary bolt with three radial locking lugs at the front. It features a steel receiver, a Picatinny rail on top of its receiver for mounting various optical sights and on the stock bottom for bipod mounting. The barrel is a free floating barrel that can be equipped with special muzzle brakes that have a mounting interface for quick detachable suppressors. It is offered in various barrel lengths of 16-, 20- and 26-inch for the .308 Winchester (7.62×51mm NATO), 23.5- and 27-inch for the .300 Winchester Magnum, and 20- and 27-inch for the .338 Lapua Magnum.{{Cite web|url=http://www.berettadefensetechnologies.com/sites/default/files/content/specs/sako-trg-m10-bolt-action-sniper-rifle.pdf|title=Sako TRG M10 Official Specifications by Beretta (PDF)|archive-url=https://web.archive.org/web/20170713042851/http://www.berettadefensetechnologies.com/sites/default/files/content/specs/sako-trg-m10-bolt-action-sniper-rifle.pdf|archive-date=2017-07-13|url-status=live}} Ammunition feeding is by a double-stack detachable box magazine which is marked with appropriate number of large dots that are embossed into the sides of the polymer baseplate and that holds 11 rounds of .308 Winchester (7.62×51mm NATO), 7 rounds of .300 Winchester Magnum, or 8 rounds of .338 Lapua Magnum.{{Cite web|url=http://www.berettadefensetechnologies.com/sniper-rifles/trg-m10-bolt-action-sniper-rifles|title=TRG M10 Bolt Action Sniper Rifles {{!}} Beretta Defense Technologies|website=www.berettadefensetechnologies.com|language=en|access-date=2017-07-10|archive-url=https://web.archive.org/web/20170708101553/http://www.berettadefensetechnologies.com/sniper-rifles/trg-m10-bolt-action-sniper-rifles|archive-date=2017-07-08|url-status=live}} Alternatively, cartridges can be singly loaded directly into the chamber.

The TRG M10 has a side-folding and fully adjustable buttstock, featuring an aluminium middle chassis frame, side-folding buttstock, and a fore-end with the M-LOK rail interface system that allows for direct accessory attachment onto "negative space" (hollow slot) mounting points, ambidextrous controls, a manual safety that is located inside the trigger guard which is in front of the trigger, and uniquely designed tactical indicators which helps identify different modular components for different calibres, where every calibre-depending component is specially marked so users can recognise the calibre of each part visually or by touch. For example, for the .308 Winchester barrel and bolt are marked with single annual grove, whereas for the .300 Winchester Magnum are marked with two groves and three for the .338 Lapua Magnum. Another unique feature of the rifle is that all of the tools that are necessary to change the calibre are built into each of the bolt handle; the small torx key is built into the centre of the bolt knob and the barrel wrench is integrated into the base of the bolt handle. An additional set of Torx keys are stored inside a small detachable polymer forend, which are necessary for full disassembly of the gun.{{Cite web|url=http://modernfirearms.net/sniper/sniper-rifles/fi/trgm10-e.html|title=Modern Firearms - Sako TRG M10 Sniper Rifle (Finland)|website=modernfirearms.net|date=18 October 2015|language=en|access-date=2017-07-10|archive-url=https://web.archive.org/web/20170706100755/http://modernfirearms.net/sniper/sniper-rifles/fi/trgm10-e.html|archive-date=2017-07-06|url-status=live}}
