Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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.
