Strike Industries AR Carbine Flat Wire Buffer Spring

Upgrade your buffer system with the Strike Industries AR Carbine Flat Wire Buffer Spring. The flat wire spring increases service life, smooths out the shooting cycle, and outlasts your rifle's stock spring. Plus, this spring provides a higher bolt load and a lower compression force, improving reliability during cycling. If that's not enough, this spring is cryogenically stress relieved to provide greater consistency and a longer spring life. This spring features 17-7 ph steel for unmatched durability and strength.
