Top 3 80 Percent  Lower Receivers of 2019 (.308, AR9, Premium Billet)

With 2019 in full swing (and that juicy tax return likely burning a hole in your wallet), we felt it was high time we reviewed the top 3 80 percent lower receivers of 2019! Ready to build your next black rifle – or pistol? Today we’re going to be checking out AR-10 lower, our new AR9 pistol lower, and our O.G. Premium Billet lower, specifically made for 5.56 and .223!

Let’s get started:

#1: Black .308 80% Lower Billet Fire/Safe Engraved (1-Count)

Ready to venture into the world of medium- and long-range shooting with your next black rifle? Our Black .308 80% Billet Lower is the ticket! This Gen 1 DPMS-compatible 80% lower comes ready to accept .308 cartridges and a DPMS fire control group, allowing you to affordably build your own AR-10 clone.

Our .308 80% Lower is proudly made in the U.S.A. from 6061 T6 billet aluminum – the same quality stuff you’d find on the gun store shelf. It comes pre-engraved with the necessary Fire and Safe markings, so all you need to do is machine the fire control group and drill a few holes! But our .308 lower isn’t just an alternative to retail pieces.

We made some upgrades to improve function and form, including an enhanced and reinforced trigger guard pre-installed, as well as a broached mag well for quicker and more intuitive reloads. Grab yours with a jig and get building!

*This Lower is compatible with DPMS Gen 1 .308 components. May NOT be compatible with ArmaLite AR-10 components.

#2: 9mm AR-9 80% Billet Lower (1-Pack)

Owning an AR pistol once meant shelling out some serious cash for a by-design piece, usually built by a premium gunsmith. That’s not the case anymore! Introducing our new 9mm AR-8 80% Billet Lower!

This made-in-the-U.S.A. 80% lower is built from 6061 T6 aluminum and is compatible with all standard Glock magazines! Pick yours up with a mil-spec Type III Hardcoat Anodized finish, or save a little cash and pick up a raw lower and make it your own!

What’s more, our AR-9 80% Lower is compatible with most (if not all) our 80% Jigs! That means if you’ve already invested in your tooling, you can build your AR-9 with just this lower, a parts kit, and an upper! This 80% Lower features competition-style mag well ramps for faster reloading, and we’ve got loads of AR-9 uppers for a plug-and-play build!

#3: Premium Black 80% Lower Billet Fire/Safe Engraved

Ready to build an AR-15 that’s a step above the rest? We’re proud to introduce our new and improved Premium Billet Black 80% lower! Some unique and innovative upgrades include a threaded bolt catch release hole as well as a threaded rear takedown detent hole, making final assembly too easy.

A broached mag well, enhanced trigger guard, and a lightweight billet construction make this 80% lower the perfect choice for your next 5.56/.223 AR pistol or rifle build. This Premium Billet 80% Lower is 100% made in the U.S.A. and comes backed with a Lifetime Warranty!

At around $80, our Premium Billet 80% Lower is more expensive than competing options with fewer features! Pick yours up with a Type III Hardcoat Anodized or raw finish. Grab an 80% jig, an AR upper, and a parts kit and you’re ready to build!
