The Strike Industries AR Flat Wire Spring is an economical and easy upgrade to any AR system using a carbine buffer system. The flatwire spring increases service life of the platform, smooths out the shooting cycle, reduces the distracting AR "twang" sound, and greatly outlasts the stock spring. Increased bolt load, in addition to decreased compressing force increases reliability in cycling. The SI Flat Wire springs are cryogenically stress relieved to provide greater consistency, longer spring life, and greater resilience to high cyclic rates.
