In late 1990s rifle models TRG TRG 21 and 41 were replaced in production models TRG TRG 22 and 42, respectively.
New upgraded rifles retained design source models, but got improved bed configuration with folding bipod, and a number of small changes.

Trunks are made by cold forging. All items of weapons, including guns, Sako firm produces its own. "Floating" barrel has four right-handed rifling pitch 305 mm. At the end of the barrel is threaded to attach the muzzle brake or tactical silencer. If none of these devices are installed on a special coupling shaft is screwed, which protects the threads from being damaged.
Muzzle Brake weakens impact weapons. Tactical silencer reduces the sound of the shot and changes its components so that the position of the needle can not be identified by the sound and flash of a shot.

valve has three lugs. Extractor provides reliable ejection of spent cartridges. Locking by turning inside the receiver stem gate 60 degrees. Dismantling the shutter can be done manually - without tools.
Receiver is not fixed directly on the butt, and to the aluminum bus that avoids a number of problems associated with the exact "fit" box on a bed of conventional rifles.
