It's really a case of not wanting to replace more parts than I need to. If my rifle still had the carbine tube on it I would get a stock to suit. Since it doesn't, I won't. I'm not too worried about it being adjustable, and I actually really like the look of the Servo stock after looking at it a few times, kinda unique too. If rifle length is better for suppression then that's just icing on the cake.
