The Battle Arms Enhanced Trigger Group features smooth,precision-machined engagement surfaces and Nickel Teflon coating that removes the grittiness found in mil-spec triggers and provides a cleaner "break". This single-stage trigger is functionally similar to a standard mil-spec fire control group, but with noticeably cleaner, smoother, and more consistent operation. The trigger pull weight is within mil-spec tolerances, with a pull weight around 5.5-6 pounds. All parts meet or exceed military specifications (Mil Spec).
