This is my New DPMS LR-308, that I had 737Shark build the upper for me, and install a new Rock 5R barrel on it. As well as thread so later on when I can get a suppressor for it the threading is taken care of already. I had the barrel contoured to .936 to the gas block then behind the gas block I had the barrel left at 1" in diameter because I wanted it as heavy as possible for me. I have to give a HUGE THANK YOU TO 737SHARK for the great rifle and all the help he has given me along the way
