I know it's a bit late, but I still don't know what's up with all you youngsters wanting to play with such high FPS limits. 400fps is fine for outdoors, but even the largest CQC fields in Cali have limits down near 350fps. Also, muzzle velocity =/= range and accuracy. My outdoor gun only shoots around 350 w/ .20g bbs and I still get some ridiculous range and accuracy out of it. As I don't want to kick this particular dead horse again and derail this thread any further, I will leave it at that, but take some of this as food for thought.
DarrK, if you get a mall (or any other real-world building) I will be there, plus at least 5. You can count on it.
