its great for when your aiming and it has great stability......my friend is a marksman and he shot a tree that was 3 in. wide with it and hit it spot on ALL because of the stock.......plus the guns good.
it is horribly noisey......because im always sneaking around i have to have quiet and this is no help......so what i do is just put it all the way back and have it pressing against me the whole game and that shuts it up. And it is not good for assaulting but mainly for just sniping.
its great for sniping but not good for anything else.
