If you already own a slide or upper for mil-spec AR-15 uppers, lower parts kits and buffer tubes, the RL556v3 is the AR-15 80% option that matches it. P80 Complete lists the RL556v3 as a bundle item: the frame, its jig and the cutting bits arrive together.

Sold as an unfinished frame or receiver. Check your state and local law before ordering; we do not ship where unserialized frames are prohibited.
