The Tactical Solutions X-Ring barrel has been designed to make your Ruger 10/22 rifle lighter and significantly more accurate. Machined from aircraft aluminum the X-Ring barrel has an outside diameter of 0.920″ and fits all Ruger 10/22 receivers and most aftermarket 10/22 style receivers. Accuracy is enhancedby a hand-chambered chromoly-steel bore with an 11-degree target crown. The barrel flutes reduce weight while the standard 1/2″ x 28 threaded muzzle allowsfor the addition of a suppressor or compensator. This model has a quick sand finish and fiber optic sights.
