Does anyone know much about the ‘16'' AR15 C.A.R. Kit’ from Model 1 Sales? It retails for $460.00 on their website and comes complete minus the stripped lower. I want to build an AR or two and stock up on some stripped lowers before November. My buddy is building five and he’s using the CMMG lowers with Rock River uppers. I’m pretty new to AR’s and am eager to learn so any suggestions are more than welcome. thanks
