trust me 6mm paintballs wont screw up a tank. I took hits from a sniper springer airsoft(springfield 03) at 430fps shooting paintballs. all i had on was a light hoodie. at 20 feet it will sting a little and burst but it wont cause catastrophic damage. on the other hand if you are shooting standard airsoft bbs like the .20 grams or the .12 gram standard solid airsoft rounds those will hurt like a b@@ch. 300 to 400 fps is pretty much a standard for high end airsofts. airsoft bullets bleed energy really fast and getting zapped enough times during scrimmages i really dont see 350fps as a threat. if we used standard airsoft and not paintballs there would be plastic carnage everywhere.....hmmmm
lol can you imagine kicking tamiya tanks off the battle field because its henlong airsoft paintball only! that really cracks me up, not saying tamiya people are snobby or anything but it sure would be a funny thing to witness.lol now we have a tbu,hbu,and pbu thats paintball unit to you tamiya people. hehehe
