AR-308 FDE

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 as we designed this to use a roll pin in the Bolt Catch (like an AR15) we use instead of a screw. The AR-10 type rifle does not have mil-spec standards like the AR-15 series does. This one is designd to fir the DPMS Gen1 industry standard. 

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 just fine.

You will be building a strong lightweight AR-308 that effortlessly handles any round from 12Ga AR uppers to 6.5 Creedmore and 7.62 NATO . We have been shipping this receiver for 5 years and have thounsands on the market sending rounds downrange every day. Here are a few of the more fun ones that were submitted by our builders. 

 

 

AR-10 lower

Posted by Noah on 7th Feb 2023

You cannot beat the value and weight for the price, but i am nervous to see how it will hold up, though it isn’t necessarily fragile. would I trust it with the strength of a metal one- no. But it gets the job done at less than half the cost. And on a budget rifle that’s adequate.

AR-10 Stripped Lower

This is my third lower from here and I have no reason to believe this one will be just as good as the other two.

AR-308 Lower

Posted by Jeffrey C Boisseau on 11th Aug 2021

I ordered this lower trying to reduce the weight of my ar-10. Against everyone telling a polymer lower is not a good idea they have weak points and will break. I have put over 100 rounds through my rifle and I have not been disappointed at all. Only suggestion I make is to buy an anti walk pin kit for the trigger as it's a tight fit but still walks out a little. Other than that holding up great and works great.

Blog Post About Product

Washington and Illinois AR15 Bans

Washington and Illinois have both recently passed laws banning the sale and distribution of assault-style weapons, high capacity-magazines, and switches that convert handguns into assault-style firearms. Both laws were met with strong opposition from gun rights groups, and in response, both states have faced lawsuits.
