I’m sorry, but we lost our source for the .25 barrels.

They’re all sold out, and we do not expect any in the near future.

We’ll update the website if we ever get them back in stock.

Will the big bore breech work with the breach riser and also a shroud.

6 months 18 days ago


Yes, the riser breech kit will work with the big bore breech. We have never tried to install a shroud, so that would depend on your mechanical aptitude and resources.

Well the big bore breech except a rotary magazine.

No, our big bore breech is a single shot design.

Seems to be little info about this big bore breech. Would this work for converting a 22XX to .25 caliber?

That’s what they’re for is the .25 caliber barrel. That’s the only size we currently stock.
