welcome to p8ntballer - always liked your stuff on uks, I know you like your ions, have you seen the mechanical drop in kit and the no chop bolt that yoda900 has been making over on mcb?
yes,, i talk to him a lot,, i used to get my lucky bits and bobs from him,,
the mech drop in.. very very clever,,,
a small 3 way valve..same thing as we use on the pu mag,,
the only down side i can see with that reg drop in unit is control of FPS,,
we can set the pressure at the reg,, but dwell comes down to how quick you pull the trigger,,
but for making a water proof super tough marker,, is has to be done,,and at some point i will get one of those from him,,
be ideal to have as a back up in your tool bag,, say for some reason your board went down or your battery wires broke,, in with the 3 way,,
3WAY hang on,,me two girls,, he he,, i would be so lucky
