ATI Outdoors AR-15 Buffer Spring

The ATI Outdoors AR-15 Buffer Spring (brand part no. A.5.10.1030) replaces a worn or weak factory spring to keep an AR-15’s bolt carrier cycling reliably shot after shot. ATI Outdoors builds this spring to work across commercial, military, and hybrid buffer tube diameters, giving it broad compatibility regardless of which buffer tube style a rifle is running. Made in the USA, ATI describes this spring as virtually indestructible, built to handle the repeated compression cycles of high-round-count range use without losing tension over time. It fits most AR-15 variants, making it a practical spare part or upgrade for anyone maintaining a well-used rifle.
