Default CVA Firing Bushing/ O Ring

Ok for all you CVA experts. On my Optima pistol the firing pin bushing is farther back and not flush. Cause my W209 primers to move back and forth. I don't like this. I know that you guys have posted things on this issue and have corrected it with another o ring or something like that. Were do I find it and what size. I really don't want to switch primers. My TC Triumph likes them and I want to make them work with the Optima Pistol. Thanks again as always.

The o ring for the bushing may not work for every optima due to different head space but i believe the o ring i used was a #60.

Or just use a couple wraps of teflon tape around the bushing threads for a nice snug fit.

So do i use both orings or just the 60. Does the tape make it flush and not have the primer move back and forth? Is it ok for to move like that? Just afraid of blow back especially with bh209. Sorry for all the questions. Just different from tc.

just the #60 if it will work. I say to adjust the headspace by backing it off until it lightly touches the primer and then measure the amount needed. I know with the #60 ring in my Optima i was able to adjust it perfectly out to .016 which gives a nice firm hold on the primer.

Head space how to:
