Thanks for the up date on your semi-auto striker system . Is there a difference in the Bern MKI and the Bren MKII recoil tubes , to take into consideration for the opening the bore inside Dia. , or are the tubes the same ?
The tubes are subtly different, but functionally are all the same. The ZB cz.26 variety is different enough that I'm not sure what you'd have to do to make it work.
