\n

This blank forging is the precursor to a forged AR-15 lower receiver. No milling operations have been completed on it. It\u2019s more complete than our 0% Lower Receiver, but less than 80% complete, so we\u2019re calling it a \u201c20% lower receiver\u201d.\u00a0This blank AR-15 lower receiver is a Cerro Forge lower forged from 7075-T6 aluminum.<\/p>\n

Unless you are an experienced machinist, this is a novelty item.\u00a0It requires quite a bit of machining and skill to turn this into a functional AR-15 lower receiver.\u00a0Our 80% lower jigs will not accommodate this part until this is brought up to 80% completion.<\/p>\n
