Had mine cut to 12.5-inches and run a 308 can on it. works great on full or semi-auto. i think i'm running an H2 buffer in it. Model 1 Sales barrel and havent changed a thing except wacking off several inches of barrel length. darn thing shoots great and i love the 6.5 on the AR platform. great hunting rifle as well as SHTF as far as i can tell so far sir...
