From the manufacturer

CMMG Inc Spring Firing Pin MK9. TAPCO used to make their own firing pin springs but with the huge success of CMMG these have become a popular option as well. You can either buy the CMMG spring or get one here. To ensure our springs hold up under tough conditions we give them a greay finish. So that they look and feel like the original CMMG springs we use a heavy duty Nylon head crimping tool. The CMMG Firing Pin Spring also features a finely tuned internal adjustment track for reliable ignition.
