I have a CVA Optima and an Optima V2.
I really like the V2 breech plugs and would love to use one in my Optima.

Anyone know if these are interchangeable?

Before someone asks, I know I can remove them and see if they thread up.
That isn’t my question though.

I want to know if it’s advisable from an engineering standpoint and has anyone done it.
Thanks and have an awesome day!
 
No they aren't interchangeable, unless you are a good machinist & welder and can modify the barrel and/or the receiver. Then anything is possible. I didn't hate the original breech plug design. It seemed less prone to leaks and gas cutting.
