Builder Sets

Building an AR-10? Don't shortchange yourself by mixing manufacturers.  AR-10 builds can be quite challenging due to the lack of a standardized design, unlike the AR-15.  The absence of an agreed-upon definition or mil-spec for the AR-10 can pose compatibility issues.  At Patriot Arms and Supply, we take the guesswork out of it by meticulously matching our AR-10 Upper Receivers, Lower Receivers, and Hand Guards for a perfect fit.  Our Receiver Sets are available in a sleek black anodized finish or can be customized with Cerakote options.
