The Sig Sauer 522LR is a .22LR semi-automatic blowback operated rifle. It is patterned after the Sig 55x series rifles that fire 5.56x45mm centerfire cartridges.The 522 fires .22LR ammunition and serves as a training platform for its larger counterparts due to mostly identical controls and features. It differs from its centerfire counterpart in a number of ways. The 522 series has no adjustable gas block as the 55x series does. Instead a mock gas block is installed.
