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

    .308 AR Lower

    I am assembling this lower over the next few weeks. I must say, LOOKS awesome, and sturdy. I shoot a great deal, almost 3 times weekly, and go through 300 to 500 rounds in competition. Time and ammo will tell, will report back. I am impressed with the gussets in this lower. Glad I purchased it. and glad it isn't a "Ghost Lower".

    The lack of communication was a bit alarming, however I attribute it to it being during the holidays that I made the purchase.

    Lower took a little longer to arrive. but made up for that with an engraving. well built and very light weight. Lower went together with upper nicely. looks great with setup will be purchasing another in the near future to build one for my father. He also liked the setup.
