The grip is a wierd one when I first saw it I didn't know what to think but turns out to be really comfortable. You don't need to do anything to the board as it works fine with the mq2 (the boad is possibly the best thing about the whole marker) the only thing you need to do is sand down the bolt pin a couple of mm otherwise it catches on the pilot.
cant get hold of you via pm or replying on the invert mini post mate... just wondering what you are doing about the paintball marker? I was getting a little concerned at first as I haven't heard from you since monday... give me a message back and your phone number mate so we can get it all sorted... I see on paypal that your address aint too far so I may be able to come and collect?

Barrel and bolt tube (where the balls are pumped into and shot from)
