Ultimate Jig – 80% Lower Jig for AR-10 / AR-15

After considering everybody’s feedback regarding jigs, we were able to develop our Ultimate Jig. With this jig, you are now able to build both AR-10 and AR-15 80% lowers. Our alignment tool that ensures the pocket is always centered in combination with our oversized top plates allows for very smooth and consistent finishing. Pair that with our press-fit stainless steel drill bushings and depth gauge (included with the jig), and you will have yourself the perfect tool to finish any top-tier AR rifle. Besides your jig and tools, the only thing needed to get your project going is a drill press or a hand drill and router.

Note: Our jigs are not compatible with billet lowers from 80% Arms or 5D Tactical, as they are not mil-spec on the outer dimensions.

Note: Due to ATF final rule 2021R-05F, you cannot order an 80% Lower and jig-related products at the same time. If you have both in your cart, you will not be able to complete the checkout process.
