Heavier- than-normal barrel (measuring .866" at the muzzle), it also gets a fully-adjustable trigger very similar to the one found on the 557. This trigger is able to be finely adjusted and is a superb choice for target shooting. Its Turkish walnut stock is impressively ergonomic with stippling in all the right places, a vertical pistol grip and a wide forend. The MTR is threaded for use with a suppressor (1/2"—28 in 223, 5/8"—24 in 6.5 Grendel).
