Sprinco AR-10 / AR-308 Enhanced Ejector Spring

Just like their buffer springs, the Sprinco AR-10 Ejector 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 ejector spring is designed for AR-308 bolt carrier groups and provides a similar spring pressure to OEM but will keep that pressure much longer. Whether you are replacing worn springs or setting some aside for future use, Sprinco springs are the only ones you will ever need.

• For AR-10 BCG
