80 Percent Lower Jigs & Tools
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. Use your jigs and tools on our selection of 80% lowers or complete 80% receiver sets!
