"Tuned to perform, the Match Target Rifle is a bit different than most 527s. Not only does it have a 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. Though it lacks the Single Set function of other 527s, this trigger is able to be finely adjusted and is a superb choice for target shooting where precision is required.
Its Turkish walnut stock is impressively ergonomic — with stippling in all the right places, a vertical pistol grip and a wide forend that’s perfect for riding a sandbag.
The MTR is threaded for use with a suppressor (1/2×28 in 223, 5/8×24 in 6.5 Grendel)." -CZ
