The Strike Industries Flat Wire Buffer Spring (brand part no. SI-AR-FWS-C) is a silver stainless steel spring built as an economical upgrade for any AR carbine buffer system. The flat wire profile increases the spring’s service life over a standard round-wire spring and smooths out the shooting cycle shot to shot. It also increases bolt load while decreasing compression force, a combination that improves cycling reliability across a wider range of ammunition and conditions. Builders looking for a simple, drop-in reliability upgrade get one that outlasts the stock spring without changing anything else in the buffer system.
