Yes old news, but noone else was going to tell him that, It is the newbie forums so I assume he didnt know.
I was the only that answer his questions without asking his age, If he was 14 or 41, it wouldn't change the fact he has the gun already or what he is going to do with it, all he wants to know is his approximate fps if he put a .43g bb in his gun, so I gave him my answer along with my reasoning.
Last time I checked this is a forum full of information not inquiring of age
