I just bought a blk. trg22. After sigting in @ 100yds. it is clearly a tack driver if I do my part. Problem is I notice the right side of the forend was cracked the mag.well up.Sent it back the dealer replaced the forend no problem. After receiving it I went to cycle the bolt and it only travels 3/4 the distance before a metal to metal stop. Saftey is off magazine out and bolt wont advance or rotate. Any thoughts?
