The Cheapest 80 Lower Receivers of 2019

Summer’s finally here! The weather’s perfect and conditions are just right for range day. But you want to throw some rounds down range with a shiny new AR-15, right? Of course, before you do that, you’ve gotta build it. We’ll keep it short and sweet today: What’s the cheapest 80 lower receiver of 2019? We picked the most affordable options (raw and coated) available for 5.56 and .223, .308, and 9mm. Find them all right here! Take a look:

#1: Raw 80% Lower (1-Count) – $55

What you see is what you get! This is the most affordable metal 80 lower receiver currently available on the market. Anything you find elsewhere is not going to include the requisite “FIRE/SAFE” safety markings (and that’s a big no-no). Most folks don’t have the tools to engrave, so we did it for you!

This raw lower’s built to function exactly like any mil-spec, off-the-shelf stripped receiver:

  • Mil-spec forged 7075 T6 aluminum
  • Pre-engraved with “FIRE/SAFE”
  • 100% made in the U.S.A.
  • No FFL required for purchase!
  • Lifetime warranty

Builders who enjoy custom coatings like this raw lower because it’s a blank canvas. It’s ready for your own anodizing, Cerakote, Duracoat, or other finish.

#2 : Black 80% Lower Fire/Safe Engraved (1-Count) – $60

The O.G. forged and anodized 80 lower receiver. This unit is responsible for hundreds of AR-15 builds, and for good reason: It’s the most affordable lower that comes coated! It’s our personal favorite, one of our first lowers we ever introduced. It boasts some nice specs and features, too:

  • Mil-spec Type III hardcoat anodized finish
  • Mil-spec forged 7075 T6 aluminum construction
  • Ships pre-engraved with “FIRE/SAFE” markings
  • 100% made in the U.S.A.
  • No FFL required for purchase!
  • Lifetime warranty

This forged lower looks, feels, and functions exactly like the mil-spec receivers the U.S. Military puts in their service rifles. Machining this one is pretty simple, and we paired it with the cheapest jig to make building your AR with it even easier.

#3: Polymer 80 – AR-15 80% Lower Receiver and Jig Kit – $75

This lower’s quite interesting (and uniquely affordable) because it includes its own, proprietary jig. Alloy lowers do not include a jig by default. If you don’t already own one, then the Polymer 80 Lower and Jig might be your best bet if you want to build your first rifle or pistol for the least amount of money possible. Never heard of a polymer receiver on an AR-15? On the fence? Read more about it here. We broke down its build quality and, well, learned whether it’s any good (which it is):

  • Weighs just 0.3 pounds
  • Composite solid core design
  • Stiffened magazine well
  • Reinforced buffer tube housing
  • Integrated trigger guard
  • Works with any 80% jig
  • Made in the USA
  • Backed by Lifetime Warranty

#3: Premium Black 80% Lower Billet Fire/Safe Engraved (1-Count) – $80

Builders looking for something that’s practical, affordable, but high-quality will enjoy the Premium Black 80% Lower. This billet receiver’s also pre-engraved with the appropriate “FIRE/SAFE” markings. For a few extra bucks, you can enjoy a unit that boasts some pretty cool features you’ll appreciate:

  • Made from 6061 T6 billet aluminum
  • Mil-spec Type III hardcoat anodized finish
  • Threaded bolt catch hole
  • Threaded rear takedown detent hole
  • Broached mag well for quicker reloads
  • Integrated, heavy-duty trigger guard
  • 100% made in the USA!
  • No FFL required!

The Premium 80 lower receiver uses threaded bolt catch and rear takedown detent holes. This little detail makes final assembly way easier. No more fumbling with springs and tiny roll pins! Lose one, and your entire AR-15 build’s on hold – so we got rid of all that.

This lower also includes the necessary screws and hex key for these new accommodations, so any standard AR-15 lower parts kit will still work with it.

#4: Raw .308 80% Lower Billet Fire/Safe Engraved (1-Count) – $90

Raw .308 80% Lowers Billet Fire/Safe Engraved (1-Count) - Blog Photo #4

Ready to jump into the medium- and long-range world of .308 AR rifles? Then we’ve got you covered! At around $90, this 80 lower receiver is the most affordable LR-308 option you can buy. Built from 6061 T6 billet aluminum, the raw .308 lower’s perfect for your DPMS build:

  • Works with DPMS Gen 1 (Lr-308) parts
  • Pre-engraved with “FIRE/SAFE”
  • Broached mag well for quicker reloads
  • Integrated, heavy-duty trigger guard
  • 100% built in the U.S. of A.
  • No FFL required to purchase

Build it, slap on a coating or finish of your choice, and grab an LR-308 upper. The beauty of this lower is that it’s compatible with all the 80 lower jigs we sell. No special tooling or bits are required to complete it. Want this same lower with that sexy Type III hardcoat finish? Easy, grab it here for $100.

#5: 9mm AR-9 80% Billet Lower (1-pack) – $150

We broke into the close-quarters battle with the new AR-9 Billet 80% Lower, chambered in 9mm. This new pistol 80 lower receiver is the first of its kind, offering compatibility with Glock magazines and standard AR-15 lower parts kits! This lower also works with any AR-9 upper equipped with the G-9 Hybrid BCG. It’s the perfect lower for building a lightweight, high-speed shooter:

  • Mil-spec Type III hardcoat anodized finish
  • Made from 6061 T6 billet aluminum
  • Competition-style mag well ramps for faster reloading
  • Compatible with Easy Jig GEN 2 Multi-Platform
  • Compatible with 5D Router Jig PRO
