I certainly don't get out much. Once every week or two I go the the big city of Decatur. There is a Walmart there. I work at my repair shop here on my property so I walk to work.
People call me a hermit. I don't mind, I LIKE ME!!!!!
So yours is a 33.4mm long cylinder and mine (22LR) is 28.5mm long. (no fit)
If the NAA-22M (22 Magnum) is 33.4 then the cylinder might fit a 22M frame??
Maybe a NAA-22LR-CB cylinder cut down to 28.5 will fit and work as well (if yours is a 22LR-CB cylinder)????
I might waste some time/money to pursue this???
Well I knew someone would come up with something.
This guy is making a conversion cylinder for the 22M-CB to 22LR.
Fits the Companion ONLY so the frames, cylinders and hammer are DIFFERENT!!!!!!!!
