The AR-308® Receiver is designed to be stronger and lighter than anything on the market today. This receiver uses the same lower parts kit as a regular AR-15 style rifle except for the Takedown and Pivot pins which are slightly oversized for the wider 308 magazine. We invented the hybrid AR lower receiver and we used that experience in designing the AR-308. We have used our TN ARMS 15 lower in every caliber from .22 LR to 50 BMG. The AR-308 is 30% bigger and includes reinforcement in key areas. This lower receiver assembles just like an AR15 style lower.
