autococker
i believe the cocker is more accurate as it has a more stable firing platform, and because of the pneumatic's etc, has a lot less recoil when firing faster, whereas with alot of other guns the gun tends to kick up a little when firing fast. also the bolt has a lot to do with it, like evo. bolt being good to put air all around the ball evenly, and light delrin for less recoil.
But then there is the matter of pressure regulation, and low pressure guns which i cant be arsed to go into, and i havent even touched on barrels etc.!
anyone want to disagree, or expand on this?
