    what barrels are used with the big bore breaches in 25 cal marauder ????? discovery what!!! lost the paperwork from the last barrel & receiver I bought here. 9 out of 10 flys of a garbage can at 30 yrds 6x weaver fine plex I want to make another one.HELP.

    • Donnie R


      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.

    • Donnie R


      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.

  3. Corey

    Well the big bore breech except a rotary magazine.

    • Donnie R

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

  4. John

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

    • Daymon

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

  5. PJ

    Which breech do I order if I want the bolt on the right side?

    • Daymon

      Right Hand
