Ready to build a gun from scratch? Build an AR-15, AR-10, 1911, Sig P320, or Glock®-compatible handgun with your own tools and know-how? Then you need an 80% lower jig. This is the tool you'll use to machine your AR's receiver blank or your new handgun's 80% frame.

Fabricating Your Firearm With a Jig

New to this project? Start here

Now that you have a basic understanding of the process, you know you need a quality, precise jig for accurately and affordably completing your receiver or frame. We offer 80% jigs that require little to no machining experience and only require basic tools -- a hand drill or drill press, a small vise, and other hand tools -- to successfully cut and drill your new firearm.

How AR-type 80% Jigs Work

All AR-type jigs (whether you're building an AR-15, AR9, or AR-10 in aluminum or polymer) work the same: Two side plates secure the 80% lower and various top plates provide the cutting templates for cutting out the fire control cavity for the trigger, hammer, sear, disconnector, safety lever, and springs. Each side plate also has pre-drilled pin hole guides for drilling the holes required to install your lower parts kit. The AR jigs we sell are designed to work a drill press or mini-mill.

How 80% Frame Jigs Work

Handgun jigs each work a little differently. The 1911 jig provides a carbide cutting tool for completing the slide rails and barrel seat by hand, while the P320 and Polymer80 jigs provide a template for cutting the frame with a Dremel and cutting wheel. Hand files can be used for final fitment and polishing. All handgun jigs provide pin hole templates for drilling the frames to accept parts kits and trigger components.

Benefits of Using an 80% Jig

  • Completes a lower or frame in 15 minutes to 1 hour
  • Jigs include required drill bits and end mill bits for machining
  • All available 80% jigs are compatible with all available lowers and frames
  • Options are available for routers or drill presses, no complex machinery required
  • Replaceable parts are available so you can keep building more guns!
  • All jigs proudly made and assembled in the USA

80% Jigs Are Banned in Some States

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.

Your custom firearm build awaits.
