PSA AR-15 Complete Lower Magpul MOE Edition - Black, No Magazine. We start with our standard single-stage government-style fire control group, finely polish the contact surfaces and then coat the hammer and trigger in a super slick nickel finish. The result is a trigger that is substantially smoother than mil-spec. A great economical upgrade.
