Buying a new marker and i have about 200 dollars give or take to purchase one. Now the ion i can buy:
got a CP no friction asa brand new, shocktech mini-drop, cp twistlock feedneck with halo collar, brand new board (stock but diff version from manufacture.) its set to 15.1 BPS at the moment. brand new qev's and a brand new CP roller trigger
