In this kit, you will find everything you need to convert your AR-15 Mil-Spec lower into a PSA JAKL Pistol Lower. Featuring a Classic A2 grip and PSA Triangle Side Folding Brace, as well as our enhanced polished trigger (EPT) which helps reduce pull weight, and is built to last. Also included are the JAKL stock adapter assembly & JAKL proprietary bolt catch that are required for your lower to function with our PSA JAKL upper assemblies. *The included Blue LoctiteA(R) must be used for the threaded adapter and adapter screw to avoid backing out during the use of the firearm.
