Hi team, I havent posted in here for a very long time, but Im getting back in to modding my 2250b. I am after the size of the o ring on the bolt? Anyone know the exact sizing? Also keen to get any ideas on good silencers, especially any leads on stl files for 3d printing. I have access to some good 3d printers at work.

Any help appreciated.

Cheers

don't know size, but you could just measure probe then I'd of barrel and make O ring have a 5% crush. So if 5.5 make O ring slightly bigger.
