Firehead, I'd say that in order to get near the accuracy of a Tanaka M40, it'd need a metal hop and a longer inner barrel...both of which are damn near extinct for it. Paired with kicbb's metal hop chamber, it's actually a decent gun, but, well, nobody has those.
Mooncruiser...do you know what it would be like trying to accurately shoot a .2 BB at 500FPS? Please. :roll: stands. End the chairsofting...garner experience, then form correct opinions.
