Machined from 6061-T6 aluminum, the X-RING barrel has been designed to make your Ruger 10/22 rifle lighter and significantly more accurate. The X-Ring barrel fits all Ruger 10/22 receivers and most aftermarket 10/22 style receivers. Accuracy is enhanced by a rifled chromoly steel liner with a polished 11 degree crown. Threads allow easy addition of a TacSol suppressor or compensator. With plenty of color options, you will have no issues finding a barrel to match your custom rifle. X-Ring Barrels ARE compatible with the Ruger SR-22 Rifle.
