Nice barrel for the money
I just assembled a rifle for a buddy with a Green Mountain 16" fluted 1/7 barrel, a S&W lower, Vltor MUR upper, Troy MRF-MX rail and a Spikes BCG. It seems like a nice barrel. Light weight and the machining and finish look great. Accuracy was as good as one could expect from a 16" barrel with cheap ammo. There is a nice recessed crown hiding under the flash hider. It is markeed 5.56 but I can not say for certain if it is as I have no way of checking it. It functioned flawlessly through 200 rounds of Federal .223 55gr fmj during its first trip to the range after being put together. My buddy was pretty happy with it. I went ahead and ordered another one for a lightweight build of my own.
