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.
