DPMS Gen 1 Style lower receiver for the 7.62x51/ 308 cartridge

This item must be sent to an FFL dealer


  • Half the weight of a metal lower

  • Lifetime Guarantee

  • Easy Assembly

  • Tactical Colors available 

The AR-308® Receiver is designed to be stronger and lighter than anything on the market today. 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. AR308 lpk is available here: with the roll pin (like an AR15) we use instead of a screw.

The AR-10 type rifle does not have dimensional standards like the AR-15 series does. Not all upper receivers will fit as well as others. We recommend upper receivers from Aero Precision, Head Down Products, Delta Tactical, and the Palmetto State Gen 2. Any AR-15 style trigger will fit fine. 



 Weight is 6.3 ounces

    Despite the long leads times because covid the lower was at my ffl within 10 days. It looked great and still does. Everything went together as it should. The rifle shoots great! Thank you for a great product.
