Billet 80 Lower Jig Kit

If you’ve been on the fence about machining and finishing your own 80 percent lowers to complete your first (or next) AR-15 build, you’ve found the perfect solution in our billet 80 lower jig kits. Our premium billet lowers are made from quality 6061 T6 aluminum and make for the easiest machining process of any 80 lower. With the inclusion of our quality Easy Jig and 5D Tactical jigs in each billet 80 lower jig kit, even first-timer users and novice builders can master the process of finishing an 80% lower in as little as 30 to 45 minutes.

Our billet lower receivers are CNC machined by some of the nation’s finest gun makers – all you need to do is complete the fire control group area and drill a few holes! Each of the jigs included in our billet 80 lower jig kits is made from hardened steel and each pre-measures and gauges all the holes and milling points you need to finish your lower.
