thank for the input guys, alot to digest.
another question you guys should be able to answer. now as i understand it snipers are alowed to be about 500fps max, and i think that is close to the actual legal limit from what i've read (2.5 joules of energy). now i was looking at a king arms blaser rifle, i like the look of it, they recon about 430-450 fps out of the box. so i was looking at upgrade springs etc available. a m170 spring was rated to 550fps and the m180 spring to 600fps. WTF? how is that? and how could i uprade a blaser to about the 500 mark?
