Just like their buffer springs, the Sprinco AR-10 Extractor Springs are made from high quality Chrome Silicon wire stock that has been heat treated, stress relieved, and cryogenically processed to produce long lasting durability. This dual extractor spring upgrade kit is designed for AR-308 bolt carrier groups and provides a higher spring pressure than OEM springs for reliable function even in adverse conditions.
