Billet Lower Receiver

Our billet lower receivers are the easiest to machine at home, so you can transform that hunk of aluminum alloy into a quality stripped AR-15 lower receiver in no time!

Made from 6061 T6 billet aluminum alloy, our billet lower receivers are made from the same exact stuff your store-bought AR-15 is made from, only you get to save a ton of money by building it at home!

Billet lowers are available for the AR-15, LR-308, and the new AR9 platform!

Complete Your Lower in 2 Hours or Less

Machining billet lower receivers takes no time at all with the aid of an 80 lower jig. Most jigs allow you to machine billet lower receivers in as little as 2 hours, to just 30 minutes.

With CNC machining and 80% completion, all you need to do is drill a few holes and mill out the trigger assembly area, and you’ll have a fully functional AR-15 lower receiver for your next rifle or pistol build!

Type III Hardcoat Anodized Finish (Mil-Spec)

Our billet lower receivers feature a mil-spec phosphate coating, so they’ll match perfectly with any other AR-15 upper receiver assembly.

No FFL Required to Buy, Own, or Build 

What’s more, you need no paperwork or background to purchase and machine our billet lower receivers – the ATF says they’re not considered firearms until you’ve machined them.

Owning and building our billet lower receivers is 100% legal in 50 states. Proudly made in the USA, these billet lower receivers will afford you a top-tier AR without the high price.
