this will be the drill size diameter you will need, then screw plastic bush back in suppressor, now you will need a lathe with a 3-jaw chuck, wrap thin cardboard around your suppressor (dont overlap) its just for protection so you dont scratch it....

put correct diameter drill in the tail-stock and slowly drill out the excess material from the bush, chuck speed around 600 RPM should suffice, go slow on break through as sometime the drill will grab.....de-burr both edges.....done!

ive got two DPT suppressors, 3 bushes, did mine this way easy-peasy!!!!!

Although that can work if you drill the bush over size. You are best to clock the suppressor up in a four jaw chuck and then bore the bush (not drill) so everything is perfectly concentric. We normally machine the bush slightly oversize by 0.05mm. If everything is not perfectly concentric and the bush is tight then the suppressor can load up one side of the barrel and cause accuracy issues.
