These trigger springs are constructed form high quality carbon silicon wire, instead of the usual music wire. The result is a lighter trigger pull and decreased lock time. The National Match version is made specifically for two stage triggers, and allows the user to increase the first stage weight and decrease the second stage weight while maintaining required service rifle match specifications for trigger pull.
Finish: Chrome silicon coated
Features: Spring is extra-power but is same installed height as a factory spring.
Gunsmithing Required: Yes
