PSA JAKL 5.56 Lowers With F5 MFG Brace are now available!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. This lower is complete with a Magpul MOE grip, FDE & F5 MFG Pistol Brace.
