Durable, abrasion resistant bolt buffer prevents contact between the bolt and stop pin to eliminate battering. Acts like a shock absorber to provide smooth, quiet cycling without the metal-to-metal contact that so easily damages the bolt stop pin holes. Replaces bolt stop pin at rear of receiver. Polyurethane construction is resistant to most solvents.
SPECS: Polyurethane, blue tint. Fits 10/22 .22 LR only.
