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

    Well made. Solid. Only complaint i have is the bolt catch tang well (snot sure if that’s what it’s called) had to be filed just slightly in order to get the tang to lay all the way into the well so the bolt wouldn’t catch. Other than that it works great!

    LR-308 Lower receiver

    Posted by Arthur Vogt on 26th Apr 2021

    Working fine so far. My o ly co.plaint would the lack of threading for the bolt catch pin. I wound up boring both of mine out with a Dremel and hitting it with a little lock-tite.
