Product Details
This is a solid lower receiver if you're building an AR-15 from scratch or upgrading what you've got. It's made from billet aluminum (that's a single piece of metal machined down rather than forged), comes in black anodized finish to resist wear, and works with standard AR parts you'll find anywhere. Fits 223 Remington or 5.56 NATO ammunition, so you've got good options on what to shoot.
