my UMG shot anywhere from 160-220 fps and i wasnt doing any worse than i was with my HK11 shooting 330 fps. Heck, i was using my friends MP7 that had a range of 10 feet and i STILL got 2 kills lol
your gun could shoot 160fps, thats all you really need at XT unless your in the back room in which 240 is just fine to get BBs all the way across. It also helps that they use .20g BBs, less weight means more speed, and theres no wind to affect the trajectory.
GROUPING is what you should be worried about, but you say your a noob so you'll likely be on full auto most of the time, you wont need to aim
I'd say the gun is just fine for XT.
someone else having an advantage of 40fps just means if you shoot at the same time their BBs will hit you a split second before you hit them, and if you aimed right you'll both be hit anyway lol
