DPMS Gen 1 Style lower receiver for the 7.62x51/ 308 cartridge
This item must be sent to an FFL dealer
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: https://www.tnarmsco.com/tn-arms-ar308-lower-part-kit/ 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
Does everything it needs to. These have been VERY tight with Aero uppers and a work of warning, the metal insert for the serial number does not allow a geissele trigger to work properly. I will need to do some modifications to the back to get it to work. Other than those 2 things, very happy with TNarmsco at every level!
I have sold these to several customers and each of them has had nothing but great reviews on these lowers. They are top of the line, about half the weight of a normal lower and very cost effective.
When I receive my AR10 stripped lower it looked alright.
As I was putting it together I noticed a few things that were wrong. 1-The foward assist hole to put the pin in was way to small,I had to use a tap screw, 2- The mag release on the lower was so wide that I was unable tighten the screw flush with the release button. 3- The rear release ident-pin hole was drilled to close to the edge causing it to extend out. I was unable to break the weapon down. I had to take the pistol grip off to get the ident-pin out and was unable get the upper off. I believe you have a grate product but these problems need to be corrected. If there is anything you can do rectify this problem it would be greatly appreciated. I have photos of the problems I will try to attach them. Thanks God bless
A representative from TAC has reached out to address concerns.
I purchased this lower for a customer, it is by far the best lower on the market, for the money, stength and weight. I highly recommend this lower and all the others here .
Well let me start by saying if you wanna start a build plan on three weeks to be shipped out. Out of the box it's really nice! Magazine release didn't fit, was really tight had to smooth it out to move freely. The safety detent hole is just slightly over sized made the safety sector really sloppy. But my upper fit really tight which I like.
I am an experienced rifle builder, Army veteran, and shooter. I have build many rifles on aluminum lowers and several on polymer lowers. I chose this lower based on reviews and color. I was truly impressed with the solid feel and the tolerances for parts are precise and accurate. I will be buying more. If the most popular pistols in the world, Glock, S&W, Springfield Armory, FN, SIG, Ruger, etc, are using polymer frames, then it is time we accepted that polymer lower rifles are the future.
I was pleased overall with the ar-15 lower I purchased last year, but the ar 308 reciever takes the polymer reciever to a higher level of precision. Very impressed with the TN Arms product
Hope you keep making this lower
Overall this is a great product, and I'm very satisfied with the purchase. The polymer feels solid and fit great with my smooth side DPMS upper. The only issue I had was that some of the polymer ran onto the threads for the receiver extension, and I had to scrape it off in order to get the buffer tube to screw in. Would definitely buy another one.
