Specifically designed for use with a silencer, the Tactical Solutions X-RING SBX barrel is a lightweight and highly accurate. A silencer is easily threaded on to the 1/2"x28 threaded muzzle inside of the barrel shroud. Hand-chambered for 22 LR, with a target crown and chromoly bore, the X-RING SBX barrel is everything you could ask for when using a silencer with a .22LR barrel. It is compatible with .22 LR rifle barrels for the Ruger 10/22, Thompson/Center T/CR22 rifles, Tactical Solutions X-Ring semi-automatic .22 rifles, and for Tactical Solutions X-Ring .22LR receivers.
