Juggernaut TacticalAfter considering everybody's feedback regarding jigs, our friends at Juggernaut Tactical were able to develop this patent pending Ultimate Jig. With this jig, you are now able to build both AR-10 and AR-15 80% lowers. The included alignment tool that ensures the pocket is always centered in combination with over-sized top plates allows for very smooth and consistent finishing. Pair that with press fit stainless steel drill bushings and included depth gauge, you will have yourself the perfect tool to finish any top-tier AR rifle. The only thing necessary to get your project going is a drill press or a hand drill and router; everything else provided in your Ultimate Jig Kit.
