An AR-10 80% jig is required to cut and drill your LR-308 or AR-10 80% lower receiver, making it ready for assembly. If you bought a complete LR-308 rifle kit with lower included, these are the jigs you need. To assist with the machining process, every .308 lower jig comes with easy-to-follow instructions for drilling each pin hole and cutting the fire control cavity. Regardless of the maker, each jig comes with various metal (steel or aluminum) templates with pre-cut holes and shapes for fabricating your AR-10 lower. Also included with each jig are the required drill bits for the parts kit's pin holes, and end mill bits for cutting the trigger, hammer, and disconnector cavity.

Our AR-10 Jigs are designed with first-time builders in mind, so we have built-in safeguards to prevent common errors, drill bit depth guides, a manual and tutorial videos to make the process even easier! With instructions and basic tools in hand, you can confidently complete your AR-10's lower in around one to two hours. These jigs are also built to last!
