Sprinco M4 / AR-15 Extra Power 5-Coil Extractor Spring
Manufactured by Sprinco USA
Just like their buffer springs, the Sprinco AR-15 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 5 coil extractor spring is designed for AR-15 bolt carrier groups and provides a higher spring load than OEM springs for more reliable extraction in adverse conditions. Whether you are replacing worn springs or setting some aside for future use, Sprinco springs are the only ones you will ever need.
