BUILD a LIGHTWEIGHT AR-10, AR 308, 308 AR RIFLE

One of the biggest drawbacks of the AR-10 and 308 AR platforms is how much these rifles can weigh. While weight is often a good thing for target shooters, it can make the AR-10 and 308AR less than desirable for some applications such as hunting or extended off-hand shooting. Note we are using the term AR-10 because that’s the term most visitors search for. We are not building an AR-10, we are building a DPMS compatible 308AR.
