The AR-308 Receiver is made in the same style as our incredibly successful TNARMS-15 but has been designed for the longer cartridges of the 308 Win, 6.5 Creedmore, and others needing just a bit more firepower than the AR-15 platform can handle. The end result is a AR-308 rifle that is much lighter with some customers (and us here at the shop) building semi-automatic rifles weighing the same as most companies AR-15 style rifles.
The AR-308 is built to accept the DMPS Gen I upper receiver due to the wide availability of parts and accessories on the market.
Notes about the 308. Unlike the AR-15 style there really aren't hard and fast standards about what is and what isn't a 308 model AR. Even within the AR-308 world there is a ton of variations in design. We recommend using an Aero Precision M-5 Upper , Bear Creek Armory 308, JSE Surplus, or the GENII 308 upper from Palmetto State works fantastic.
