Completing your black rifle or pistol without having to pay extra fees, or dealers' premiums, means investing in an AR-15 80% lower. This incomplete receiver blank isn't functional: It hasn't been completely drilled and can't accept a lower parts kit. To make your 80% receiver into a proper AR-15 lower, you'll need an AR15 jig, like the ones listed here.

How The AR 15 80% Jig Works

The AR 15 jig replicates the same milling and drilling procedures a commercial arms maker uses to fabricate an AR-15 stripped lower receiver. Using two side plates to secure the 80% lower, various top plates are then installed atop the side plates to act as cutting guides for completing the interior cavity of the receiver, making the correct space for installing a lower parts kit.

Once finished cutting the inner cavity with the provided bits, you'll drill the pin holes for the trigger, hammer, disconnector and safety lever. The side plates have pre-drilled guide holes to show where you to drill. The jig does most of the work, requiring you to only control the drill press or mini-mill you'll use with the jig.

Here's an in-depth guide showing how an AR-15 jig works.

AR-15 Jig Features and Specs:

  • Completes an 80% lower in 30 minutes to an hour
  • Requires basic hand tools (drill press or mill, vise)
  • Compatible with all 80% lowers we sell!
  • Includes required bits and tooling
  • Easy-to-follow instructions included!

State Laws May Vary

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 AR-15 build awaits.
