Our Easy To Use Jig is a builder friendly jig that can be used for AR15 and 300 Blackout Projects (FCG pocket is the same on both). All of the parts that come into contact with cutting tools are made out of solid steel. Our Jig includes multiple top plates, including the "multi-hole" plate that guide you on where to drill and mill the remaining 20% of your AR15 80% lower. Unlike other jigs ours is designed for both home/garage drill press and manual mill - this way you can be sure you'll have what you need regardless of how you decide to tackle your build.
