PSA JAKL 9mm Lowers 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 & F5 MFG JAKL pistol brace.
