The Strike Industries Carbine Flatwire Spring is an economical, easy upgrade to any AR system with a carbine buffer system. The flatwire spring increases 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 and makes shooting more comfortable. At a cost not much greater than stock carbine springs, the SI Flatwire is an easy option for those either looking to replace worn buffer springs or begin new builds.
