Premium 80% Lower Receiver – Billet (Fire/Safe Marked)

$77.00

We got tired of messing with roll pins and flying detent springs, so we fixed it. This isn’t just another 80% lower. This is our redesigned billet model, built for a smarter, more straightforward build process. If you’ve ever cursed a bolt catch pin or spent twenty minutes searching for a rear takedown spring, this lower is your solution.

The key upgrades are simple but game-changing: threaded bolt catch release hole and a threaded rear takedown detent hole. That means you use a hex key instead of a punch and hammer. The included screws install cleanly, applying perfect pressure without the risk of mangling your receiver. You get a secure, professional-grade fit with basic tools and far less frustration. It’s how an 80% build should be.

Machined from solid 6061-T6 aluminum billet, this lower is tougher than forged counterparts. It features a clean, broached magwell, a permanent integrated trigger guard, and a durable Type III Hardcoat Anodized finish in matte black. The “FIRE” and “SAFE” engravings are deep and legible, giving you a professional, finished look right out of the box. It’s 100% mil-spec for compatibility, so it pairs perfectly with your standard AR-15 parts kits and uppers in 5.56/.223, 300 Blackout, or 6.5 Grendel.

This is for the builder who values precision and hates unnecessary hassle. You’re paying for intelligent design that saves time and delivers a superior result. Every piece is made right here in the USA.
