Breech O-ring replacement. PITA or no?

Nothing wrong with the gun, as far as I know, but it’s been around the block a time or two.

Thinking maybe the 90 durometer upgrade to the breech seals might be a cheap and easy way establish a base-line for performance. It’s a good excuse to tear my gun down as well, which is the excuse I was looking for. 😉

I’ve searched and seen all the FAQs about the procedure, just wondering if anyone has any tips above and beyond the posted procedures.

For that matter, where do I find 90 durometer O rings on the cheap?

Thankya…..
