Chrome-Silicon Steel Flat Wire Spring

This buffer spring is made from chrome-silicon steel. It uses a flat wire design, which sets it apart from a standard round wire buffer spring. The flat profile of the wire is the main feature buyers look for in this part. Strike Industries offers it as a dedicated flat wire option for AR-10 pattern rifles.

AR-10 Carbine Receiver Extension Compatibility

This spring is compatible with standard AR-10 and SR-25 carbine receiver extension lengths. It has an overall length of 19.5 inches. The AR-10 remains the primary platform, with SR-25 and LR-308 pattern rifles also supported. Owners running a rifle length or other non-carbine tube should look for the spring that matches their tube.
