One of the great things about today’s small arms market is the easy availability of parts kits. Today’s kits make it easy to get everything you need to assemble your custom rifle shipped in one package. Do you want to upgrade your lower receiver? Okay, just enter one part number and the box will hold a complete 308 lower parts kit when it arrives. Wait! That means everyone who orders the kit gets the same parts from the same manufacturer. How is that custom? It’s not. Aero Precision understands that.
