Looking to get an 308 AR. I would like a 6 pos stock and a shorter barrel and flattop. bushmaster, dpms? Plan on using it for shooting and hunting. My armalite ar10 20inch heavy barrel is just too heavy to carry very far.. Well too heavy to shoot free handed. My dad just got a bushmaster ocr. They do not use the same mag. just wondering what your thought are? thanks Wanna kill these ads? We can help!
