Dropped on a 12 inch .20 cal barrel and thinking of putting it on my mk1 along with a kevg mk1 reg so looking for a bit of advise.

The block is a short internal pre chamber one,and the valve and body is standard as are the ports of the block and valve body,does anything need altering? Like the front/top port of the valve body? And what reg pressure will it need?

I would set reg to 1700 psi.would also open front valve port up from 5mm to 5.5mm,of course a bit more hammer pre load.dont forget it's a t15 torx to hold the core not a 3mm key
