first off to the idiot who said his gun didnt work because he charged it all night. These guns come with a very cheap battery, if you charge it for more than the allotted time (2 hours 35 minutes) you will destroy the battery.anyway the gun.This is an excelent gun for the cost, it out ranges any of the CYMA guns and simply dominates in a spring war (i would know i whipped this baby out in the middle of a pistol match and got 7 people) Its magazine is kinda difficult to load and spills bbs out if you remove it before it is empty. Also dont put the magazine in without the barrel in propperly or the mag empties into the gun. This thing has high fps around 220 -240 (yes i cronographed it) The only problem is mine doesnt really work on single because it double feeds apart from that this gun rocks.
