Our collection of forged 80% lowers are some of the most popular, trusted units available on the market. Used by thousands of builders over the years to construct AR rifles and pistols in the most popular calibers, we've honed in offering only the most reliable and proven receiver blanks. These 80 lowers start life from raw 7075-T6 aluminum, precisely forged into their final shape and refined through CNC machining. Each unit ships with a raw finish or a mil-spec, Type III hardcoat anodized coating.
Mil-Spec Fittings for Easy Assembly
Like any "retail" stripped lower receiver, our forged lowers sport mil-spec fittings to ensure compatibility with virtually all available AR-15 parts and accessories. Once cut and drilled, your finished receiver will accept any mil-spec lower parts kit, buffer assembly, trigger and pistol grip. Pivot and takedown pins are standardized to ensure compatibility with any appropriately chambered upper receiver. Our units are available in 5.56 NATO, .223 Remington/Wylde, and 300 Blackout.
