The Sako TRG are a series of sniper rifles developed by a Finnish firearm manufacturer, SAKO of Riihimäki. The TRG-21 and TRG-22 are designed to fire standard .308 Winchester or 7.62×51mm NATO cartridge, while the TRG-41 and TRG-42 are designed to fire the more powerful .300 Winchester Magnum and .338 Lapua Magnum cartridge and therefore having a standard larger action and barrel. They are available with olive drab green, desert tan/coyote brown, dark earth or black stocks, and are also available with a .

The sniper rifles are normally fitted with muzzle brakes to reduce recoil, jump and flash. The Sako factory TRG muzzle brakes vent sideways and are detachable. Generally TRGs are outfitted with a Zeiss or Schmidt & Bender PM IItelescopic sight with fixed power of magnification or with variable magnification. Variable telescopic sights can be used if the operator wants more flexibility to shoot at varying ranges, or when a wide field of view is required.

In October 2011, Sako introduced the Sako TRG M10 Sniper Weapon System. It was designed as a user configurable multi caliber modular system and does not share its receiver and other technical features with the rest of the TRG line.

In 1989 Sako Ltd. (Riihimäki, Finland) introduced the TRG-21 precision rifle as a sniper rifle model chambered in .308 Winchester cartridge. A more hunting oriented variation of the TRG was later introduced as the TRG-S M995, which uses the same receiver (short action) and bolt (different bolt handle) as the TRG-21 with the exception that the receiver is open at the top rather than possessing a cartridge ejection port on the right side as found with the TRG-21. Subsequently, a second sniper rifle with a 20 mm (0.79 in) longer scaled up magnum action emerged as the TRG-41 in order to take advantage of the .338 Lapua Magnum cartridge. Similarly, a hunting variant of this model, again using the same bolt (different bolt handle) and with the receiver open at the top was introduced as the TRG-S M995 Mag in magnum calibers up to .338 Lapua Magnum.
