The Strike Industries Carbine Flat Wire Buffer Spring is a replacement buffer spring for the AR-10 platform, with support for SR-25 and LR-308 pattern rifles. It is made from chrome-silicon steel and uses a flat wire design in place of a standard round wire spring. The spring has an overall length of 19.5 inches and is compatible with standard AR-10 and SR-25 carbine receiver extension lengths. It is part of the buffer components that go with the buffer tube on an AR-10 lower.
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.
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.
