Our prices are always the lowest, and most of our 308 and AR-10 80 lowers are on sale right now.

308 & AR-10 80% Lower Features:

All polymer .308 lowers include their own jig! The polymer jigs include the required drill bits and end mill bit for fabricating your receiver into a functional unit, too. Whether machining polymer or billet, it'll take around one to two hours to complete your lower receiver.

Compatible with DPMS LR-308

Many don't realize this, but the AR-10 and most .308-chambered ARs are not the same. The original ArmaLite AR-10 platform shares some similarities with those other rifles, but they're not interchangeable. So, we stuck with the most popular option on the market: The DPMS LR-308. Still nicknamed the "AR-10", the LR-308 is one of the most widely available and popular .308 AR line of products you can find. Our 308 80% lowers are compatible with all LR-308 parts.

Legally Build Your AR at Home

Try as politicians might, it is not illegal to build a gun at home for personal use, and no license, paperwork, or FFL is required under federal law. The ATF even says so. This means that you can buy your 80 percent lower, have it shipped directly to your front door, and get to building with an 80% jig. No paperwork required. No FFL transfer necessary. 

State Laws May Vary

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.

Your custom .308 build awaits.
