longstrike brass barrel queries

Hi guys,
I'm going to over haul a longstrike and am wanting to put in a brass barrel.
I've seen a guide on OMW's forum but there is no specification to the diameter of the brass.
eg. 9/18, 17/32
Any help would be much appreciated.

Cheers,
TOM

I'm not really sure on sizings as I have never done a BB before, but I do have a suggestion before you start. perhaps do a direct plunger conversion with spare retaliator internals, and use that breech as your base for measurements. you'll get a ton more power out of a direct plunger but you can't use a reverse plunger breech on a direct plunger setup, so you would have to redo the breech again if you decided to convert to direct plunger later on.

For something with such a small plunger volume, I'd say 9/18 would be your best bet.

Thanks for the Help Jeo and cfb rolley

Which writeup are you referring to exactly? The size of your barrel needs to match your darts.

Also 9/18 is 1/2", you guys mean 9/16".

True!
