Shop our ample selection of 80 percent lower easy jigs and complete jig systems. If you already have the right drill bits, just a jig will work fine. However, our complete systems come with the right bits and save you the hassle of having to buy them separately. Our 80% AR lower jigs and systems are ideal if you prefer to buy your 80 percent lower receiver separately or if you already have one. Choose from a standard unfinished AR-15 lower receiver or a .308 kit.
If you want to finish your lower receiver build , our 5D Tactical universal router jig is a smart choice that offers unparalleled precision. The no-touch side plates reduce the chance of accidental damage. Our simple-to-use universal easy jig is a patented router jig that also drastically reduces machining time. It fits nearly all billet and forged AR-15 lower receivers with only a few exceptions. If you are unsure about fit, please call 80 Percent Arms. For those who prefer traditional machining, we also offer drill press jigs.
