Strike Industries AR-10 Flat Wire Spring

Strike Industries AR-10 Flat Wire SpringThe Strike Industries Flatwire Spring is an economical and easy upgrade to any .308 AR system. The flatwire spring increases the service life of the platform, smooths out the shooting cycle, and greatly outlasts the stock spring. Increased bolt load, in addition to decreased compressing force, increases reliability in cycling. Additionally, all SI Flatwire springs are cryogenically cycled to provide greater consistency, longer spring life, and greater resilience to high cyclic rates. At a cost not much greater than stock carbine springs, the SI Flatwire is an easy option for those either looking to replace a worn buffer spring or begin new builds.Features Cryo-cycled chrome-silicon steel for strength, reliability, and longevity Decreased harmonics lessen system vibration for faster follow-up shots.
