I am running an 18 inch upper with a ross brake (he makes any color you want as long as you want stainless), A vortex 3.5-10 x50 diamond back scope (one of the best scopes for the price) and an A1 stock. I added a mercury recoil reducer to the cleaning kit compartment using a 2part casting resin. It is a real blast to shoot. It kicks less than my 308 bolt gun. I added a few custom decals too.
