Need replacement end mill bits or drill bits for your Elite Builder jig? Grab them here! If you already own the AR-15/AR9 variant of the EB Jig and want to complete a .308 80% lower (for an LR-308 rifle build) then simply grab the available .308 Patriot Upgrade plates! These will allow your Elite Builder jig to successfully fabricate all types of 80% lowers available on our site for 5.56/.223/6.5 Grendel and .308/6.5 Creedmoor calibers. Quality factory-direct HSS bits are available for additional receivers. We also carry replacement templates in case your jig's plates wear out or suffer from any damage.
