$141.90
Build a solid foundation for your .308/AR-10 platform. This isn’t a flimsy part; it’s the core of a serious rifle.
Built Right, Here in the USA
We start with a solid block of 6061-T6 billet aluminum, not a cheap forging. We machine it to precise specs, resulting in a lower receiver that’s exceptionally rigid. The anodized black finish isn’t just for looks—it’s a hard layer of protection against wear and corrosion. This is a permanent piece of your build.
