The Sons of Liberty Gun Works Xtra Power Rifle Buffer Spring (brand part no. SOLGW-XP-INT-SPRING) is built to SOLGW’s own small-parts line, designed to fit most mil-spec AR-15 rifle-length buffer systems. As an Xtra Power spring, it’s built with extra tension over a standard-power buffer spring, which can help ensure reliable bolt-carrier return in builds running suppressors, adjustable gas blocks, or other conditions that push more gas into the system. This AR buffer system spring is fitted for the rifle-length configuration specifically.

Frequently Asked Questions

When would I want an Xtra Power buffer spring over a standard one? The added tension can help builds running a suppressor, adjustable gas block, or other over-gassed conditions cycle more reliably.

Is this the correct length for a carbine buffer tube? No, this spring is sized for the rifle-length buffer system; a carbine-length tube needs a shorter carbine spring.
