This is the best of the best equipment I'll come down to 600 and that's as low as I'll go that's saving you over 300 dollars on this set up if you include the Co2 tank I dunno what else I can do to make you guys happy it's not like I'm selling garbage, It's 3 months old. If you don't want it for 600 please don't waste my time with a low ball offer notice in my original post there is no OBO.
