Auto mag with powerfeed,warp feed, boo-yaah,....alot of others. I also have a black magic(very nice)
i have played many tornaments with this were someone i know had a more exspencive nitro tank that broke. . if you get an expencive tank the diffrence between that tank and this is insignifigant when you get on the feild.the more complicated tanks will break on you sooner or later. this tank is very simple
get this and dont stay up the night before you play thinking if your tank is going to work.
