17-7 PH stainless steel, precipitation heat treated and stress relieved, passivated with precision tolerance, the Sprinco enhanced hammer spring is precision made to M4 TDP dimensions, crygenic processed and moly plated.

The enhanced Sprinco hammer spring "legs" lay flat so the load is consistently and evenly applied.  It is conservatively estimated to be 7 times the normal duty cycle of factory hammer spring.
