Whether you just bought an AR15 kit to start a build, or you're finishing a rifle or pistol with a forged or billet AR15 receiver blank, the AR15 jig is the one tool you need to turn your 80% lower into a finished stripped receiver. We partnered with top gunsmiths and American manufacturers to bring easy-to-use, rugged 80% jigs to the AR-15 market, so amateur builders and new shooters with no experience can build your first or next gun truly from scratch.
No Gunsmithing Experience Needed
The AR15 jig provides the measurements for cutting your 80% lower's fire control cavity, where the trigger, hammer, and parts kit will install. Each jig also includes side plates that secure the receiver for machining via its exterior walls. Those plates providing pre-drilled template holes for where you'll drill the pin holes for the trigger, hammer, and disconnector. These features remove virtually all the measuring and calculations required. All you do is secure the jig in a vise, power up the drill press or mini-mill, and let the jig guide the included bits for cutting and drilling.
AR-15 Lower Receiver Compatibility
With the receiver blank market in full swing, various manufacturers have developed a plethora of new 80% lowers. In addition to our own billet and forged units, polymer receivers now exist for building an ultra-light AR15. We've partnered with those makers to provide polymer 80% jigs that are incredibly easy to machine and super-affordable.
Forged vs. billet fitment: Some metal AR15 jigs will only work with a forged receiver blank. Billet 80% lowers often feature different exterior shapes, which do not allow for some jigs to properly seat against the receiver's walls. Simply verify compatibility with your chosen 80% lower on the product page when ordering your jig.
