Sako’s TRG sniper rifle has always been one of the symbols of global precision rifles. The precision shooting rifles of this series have been produced for a long time and are in The status of Sako’s products is basically the jewel in the crown. Therefore, the improved version of the TRG sniper rifle can be said to have a very good starting point at the beginning of the improvement. Of course, it is also a very challenging thing. The challenge is how to improve the already very good selling products?
For the TRG A1 rifle, its positioning may be to expand the user base and make the user group wider, rather than to meet the urgent need to update the outdated features in the previous generation products. The polymer butt version of the TRG22/42 sniper rifle is still in production and is still an excellent rifle in various types of shooting. It is suitable for almost any purpose that requires precise shooting of a rifle.
Since their prototype was launched, the FA website has been using TRG22 and TRG42 series of sniper rifles, so we are very familiar with these models, and we are very keen to know what new versions of the latest model of TRG sniper rifles have changed . The update of the TRG A1 sniper rifle is very important, because the design of the TRG A1 rifle has changed the appearance, so unless you are a ninja-level TRG series sniper rifle expert, you cannot recognize this sniper rifle.
In fact, the TRG A1 sniper rifle version has more changes than the previous TRG21-22 and 41-42 updates in 1999.
A brief history of TRG series sniper rifle development
The most original TRG sniper rifle was unveiled in 1989, and it can be seen more or less that it was in the Valmet sniper rifle and Sako Target sniper rifle Developed on the basis of. The above mentioned upgrades from TRG21 and TRG41 to TRG22 and TRG42 were carried out for the 2000 model. This upgrade includes updating the magazine Inoue inscription, improving the muzzle brake, using a new type of bipod, and improving the grip Angle etc. After the improvement, the Finnish army immediately adopted the new design, and the Finnish Army named it "8.6 precision rifle 2000 (8.6 precision rifle 2000, Finnish abbreviation 8.6 TKIV 2000)". The new design was an immediate success, and is currently used by government agencies or military forces in more than 20 countries. If sports shooters are included, more countries will be used.
TRG series sniper rifle basic rifles started from the two models of TRG21 and TRG41, and have been in continuous production for 29 years. This kind of long life and high popularity will not happen for no reason. At the same time, in such a long production cycle, the rifle and its accessories have undergone many natural updates and changes, but these updates and changes are quite subtle and not very obvious in most cases.
TRG 22/42, the core of the TRG A1 sniper rifle, is still a very powerful firearm. Among similar products, it has the characteristics of ergonomics, high accuracy and lightness. After the latest update, TRG22 and TRG42 are no longer the latest and greatest versions of the TRG series, but in fact the barrel, trigger and trigger components of the TRG A1 sniper rifle are the same as the TRG22/42 sniper rifle currently produced. , TRG A1 sniper rifle mainly uses a new base, which can be partially compatible with the latest products provided by Sako for the TRG M10 sniper rifle. The TRG A1 sniper rifle includes a hand guard, a folding stock of the M10 sniper rifle, and a middle part with a magazine well. The TRG A1 is functionally similar to the TRG 22/42 sniper rifle upgrade kit including ITRS and MMRS rail systems, but more Simplify and modernize.
TRG A1 sniper rifle starts with the current flagship product of Sako’s TRG sniper rifle series—the latest multi-caliber TRG M10 sniper rifle, which we receive from SakoThe TRG A1 sniper rifle is not a 100% final production version, but even if it is not exactly the same, it is very close.
The test barrel uses a 20-inch heavy-duty thick barrel. The main difference between the two sniper rifles, TRG A1 and TRG M10, is the barrel replacement and locking system. Of course, this also leads to other difference. Among them, the TRG M10 sniper rifle was originally developed to meet the PSR precision sniper rifle project of the US Special Operations Command, and it was runner-up in the final ranking. Of course, why Remington was better than the TRG M10 sniper rifle is still unclear. In 2009, the technical specifications of the precision sniper rifle project required a replaceable barrel function with many other functions. As a side effect, many civilian rifles have also begun to have a modular design trend, and most of the manufacturers participating in the precision sniper rifle project put their newly developed sniper rifles into the civilian sniper rifle catalog after they did not win the bid. The most expensive flagship model sniper rifle, the replaceable barrel is very useful in civilian use, but at the same time it adds some weight.
Main structure and function
For the positioning of a full-power sniper rifle, the original TRG22/42 sniper rifle is very lightweight, which is the lightest on the market we guess One of the original guns from the factory, especially the TRG42 sniper rifle with a .338Lupua caliber. The TRG22 sniper rifle with a .308Win caliber and a barrel length of 20 inches weighs 4.7 kg/10.36 lbs without ammunition and accessories. The TRG M10 sniper rifle with the same barrel length weighs 6 kg/13.27 lbs. The latest TRG22 A1 is somewhere in between, 5.3 kg/11.68 lbs.
TRG M10 sniper rifle, like many other sniper rifles, is described as "multi-caliber" and "modular", which may not fully conform to the original meaning of these terms, because these rifles do not contain guns that can be changed Purpose of the module.
A bolt-action rifle with magazines is still a modular bolt-action rifle with magazines after being modularized. For example, it will not resemble the originator of all modular rifles—Stoner 63 The type of modular firearm is converted from a short and light magazine-type short barrel carbine to a chain-feeding machine gun for vehicle use. But the term modularity can correctly describe the idea of this sniper rifle in its design and can well represent its basic structure.
For example, the 27-inch long .338 Lapua barrel and full-length guard can be replaced with a 16-inch long .308Win caliber barrel and short guard, and the role of the modular rifle will also change. Moreover, the TRG M10 sniper rifle can be converted within 2 minutes without special tools, because it also meets the technical specifications of the PSR precision sniper rifle.
TRG A1 sniper rifle (top) and TRG M10 sniper rifle (bottom), the new TRG A1 sniper rifle has the same stock, pistol grip and puller as the TRG M10 sniper rifle Handle; but the TRG A1 sniper rifle uses the same precision-forged chrome-molybdenum steel barrel as the original TRG22/42, while the TRG M10 sniper rifle uses a stainless steel barrel with a black cerakote coating.

This picture shows the .308Win caliber magazine used by the TRG M10 and TRG A1 rifles. The 338Lapua caliber A1 sniper rifle has a magazine capacity of 7 rounds. The .308Win caliber magazine shown in the figure is 10 rounds. The original TRG42 magazine has a capacity of 5 rounds, but a 7-round magazine is now also available. For the TGR M10 sniper rifle, its magazine is not interchangeable with the TRG 22/42 or TRG 22/42 A1 magazine. This is because the M10 rifle uses a multi-caliber design, so the size of the magazine well and magazine Must be designed according to the maximum diameterIt is suitable for smaller caliber after scaling by charging device.
TRG M10 and TRG A1 two sniper rifles are designed with the same removable plastic cover between the magazine well and the guard. This plastic cover can actually be removed with the Thorx bolt hidden inside the handle , There are additional Thorx wrenches in the cover, which can be used to remove the handguard or adjust the trigger assembly. However, if the user does not know exactly how to adjust the trigger assembly, it is absolutely not recommended to use these wrenches for trigger adjustment.
In addition, the smaller wrench in the plastic cover can be used to adjust the small screws inside the butt adjustment button. By tightening these screws, the butt adjustment button can be disabled and the buttstock adjustment position can be locked, which can prevent the buttstock from being adjusted. Intentional or unintentional adjustment. In addition to the handguard, the larger wrench can also be used to adjust the modular trigger assembly bolts.
Trigger module removal requires additional tools. The shorter end of the wrench cannot provide enough leverage to loosen the screws with bare fingers. The first of the two screws on the handguard in the picture below has been completely removed , But in the actual situation, you don’t need to do this. You only need to loosen one or two turns to completely remove the handguard; the latter screw has been completely pulled out, but it has been locked in this position. Of course, it cannot be lost if it is disassembled.
In addition, both the M10 sniper rifle and A1 sniper rifle have fully adjustable trigger modules. The trigger module used in TRG series sniper rifles is one of the best factory original trigger components in the world even if it is not the best factory original trigger component in the world.
The picture below shows the latest version of this trigger assembly. The latest version of the trigger assembly is not very sensitive to particles (sand, dirt) inside the base/case of the modular firearm.
To remove the trigger module of the TRG A1 sniper rifle, you still need to use the wrench tip hidden in the handle. The trigger assembly is fixed to the receiver by a bolt. In addition, this disassembly procedure has an additional safety function, that is, unless the sniper rifle is not in a safe state and the trigger has been pulled, the mechanical device on the Thorx bolt head can prevent the wrench Insertion, in practice, the trigger assembly cannot be removed while the rifle is ready to be fired.
Although the wrench used to remove the trigger assembly as described above is included with the sniper rifle, in fact, if you use the shorter end of the wrench to open it with a three-finger grip, it requires extraordinary strength. This is something that mortals can't have, but if you use pliers like Leatherman to clamp the wrench to turn, then this method is still feasible. A trapezoidal part on the trigger assembly in the figure below is the part that hinders the forward movement of the firing pin before pulling the trigger, that is, the blocking iron; and the bright round part is the safety pin that can move up and down.
TRG A1 sniper rifle (front) and TRG M10 sniper rifle (rear) The picture above is a group photo of TRG A1 sniper rifle and TRG M10 sniper rifle, both are equipped with typical sniper rifle accessories. Such as high-quality military-grade Steiner M5Xi 5-25 MSR2 and Schmidt-Bender PMII 3-27×56 Highpower sight with MSR2 division. Both use the excellent Spuhr-QDP lever-type sight mount for installation and fixation. The Spuhr sight mount has a very convenient accessory interface, such as a rail that can accommodate the Aimpoint T-2 optical sight.
If you need to add additional rails, the handguards will be different: the handguards of the TRG A1 sniper rifle are compatible with the Magaipu M-LOK rail system. This system was first used in Sako's Tikka On the TAC A1 sniper rifle, the TRG M10 sniper rifle's Magaipu M-LOK rail system compatibility has also been updated in 2018. But unlike the TRG M1 sniper rifle or TAC A1 sniper rifle, the rail at the 6 o'clock position of the M10 handguard is permanently fixed. At the same time, these two sniper rifles have a total of 30 MOA on the Picatinny rail on the top of the receiver. Inclination (can be used for high and low correction compensation), while the top rail of the receiver and the top rail of the handguard are aligned.The alignment of the optical sight is very important, and this kind of alignment in series installation is very beneficial.
The two sniper rifles in the photo are equipped with Hensoldt NSV series clip-on night vision devices. These two night vision devices are installed on the rails above the handguards. For the military and law enforcement agencies, the night vision devices are Use is very common, which is why Sako earlier provided ITRS and MMRS rails for TRG22 and 42.
In addition, the two sniper rifles use the Ase Utra SLi series of silencers. The thread specification of the TRG A1 sniper rifle is 18×1RH, and the SL7i silencer is installed. The thread specification of the TRG M10 sniper rifle is the same but installed SL7i BL silencer, this silencer has an inner ring silencer installation system with integrated muzzle brake. The brake has a thick thread for quick installation of the silencer and a ratchet pin system to prevent the silencer from jumping.
