In spar gm4 can easily trap you in the corner and with the fire rate and the clip you only hope is the the spread of the gun lucky Favours you. I don't think that's very balanced "limit" of a gun.
You can do the same with a shipka if you hug the bottom, thats 55k price difference...... I've won most spars with my Tzek then any other gun....
