Premium Billet 80% Lower Receiver – Fire/Safe Marked

$77.00

We got tired of roll pins flying across the garage, too. That’s why we stock this Premium Billet 80% lower. It’s machined from solid 6061-T6 aluminum to solve the headaches of a standard build, giving you a cleaner, stronger result with less hassle.

Built Smarter, Not Harder

This isn’t just a stripped block of aluminum. We looked at the common pain points and engineered them out.

• Threaded Bolt Catch Hole: Forget hammering that stubborn roll pin. Now you install the bolt catch with a simple screw and an Allen wrench. No marring, no frustration.
• Threaded Rear Takedown Detent Hole: This small change is a huge win. It traps the spring and detent during assembly, so you’re not fishing parts out from under your workbench. The included screw caps it off cleanly.
• Integrated Trigger Guard: It’s part of the billet design. No need to install a separate guard, and it’s virtually indestructible.

What You Need to Know
