Whether you’re a home gunsmith, a firearms enthusiast, or simply someone who enjoys building a carbine with their bare hands, an 80 lower is an incredibly valuable resource. It allows you to complete the final machining of your receiver in the comfort of your own workshop.

The best part? You can do it all without having to buy expensive equipment!

At 5D Tactical, we offer a diverse range of 80 lowers that can be converted with just a drill press. So, if you’ve always wanted to construct your very own carbine, you’re in the perfect place to get started.

What is an 80 Lower Receiver?

An 80 lower frame is a partially completed piece of metal that only requires milling to be made ready for assembly into a completed firearm. Therefore, if you want to build your own custom AR-15 from scratch, one of the primary steps is to obtain an 80% lower receiver blank.

What is the Advantage of an 80% Lower Receiver from 5D Tactical?

An 80 lower empowers you to build your own carbine, pistol, or rifle from the comfort of your own home workshop. In addition to the fulfillment of forging one’s own firearm, you can also save money when compared to buying whole weapons outright.

At 5D Tactical, our AR-15, AR-308, and AR-9 80% lower receivers boast fast shipping directly to your home. Better still, all of our products are proudly made in the USA and to exacting standards of excellence.

Engineered for exceptional durability, and precision-machined with aerospace-grade aluminum for superior strength, our 80 percent lower receivers ensure that you’ll be starting your AR build off on the right foot.

Our 80 Percent Lower Kits and Parts Simplify Assembly

Easily convert our AR-15, AR-10, or AR-9 lowers into fully functional receivers with our 80% Lower Jigs. Shop our unfinished receivers and kits to get all the parts you need to complete your custom build with precision and efficiency.

80% lowers require the fire control group pocket to be milled out, which is completed with a handheld compact router. A hand drill or a drill press can be used to drill the safety selector, hammer, and trigger pin hole. We offer a variety of billet and forged AR-15 80 lower receivers of the highest quality as well.

Is It Legal to Build an AR with an 80 Percent Lower Parts Kit?

Yes, because they aren’t considered to be firearms, per the ATF’s definition, you don’t need a license to purchase or own an 80 AR lower.

In order for them to become functional firearm components, they require some basic machining and drilling.

This can easily be completed in 45 minutes, or less, with our innovative AR-15 and AR-308 Router Jig Kits.

Do I Need to Register My Unfinished Receivers?

No. You don’t need to register your 80 lower because an unfinished receiver is not considered a firearm by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).
