Hey guys my Jg M4's accuracy just isn't cutting it, it isnt bad but it can just get down right inconsistent. My gun constantly curves to the right. It is probably just something simple,but I needed a new bucking a barrel anyway. I'm not really going for a dmr build (i'm staying within field fps) just good accuracy and range for a just field gun. Okay down to it I need your guys opinion on how this set up will work.

PS: Does it matter if there is leftover from the difference of your inner and outer+extension?
