Hi all. I have 2 old model single sixs with the 22lr cylinders, but no mag cylinders. I got an auction on ebay for cylinder and extra barrel, but the cylinder isn't even close to fitting my guns. The new cylinder is marked 22 mag. The base pin hole is too small on my new cylinder. Also the timeing notches are wider on the new cylinder. The length is slightly long, but I can fix that on the lathe.
I'm wondering if I didn't get a Ruger cylinder?
What are the differences between the old and new model cylinders?
thanks.

BTT

anybody know the difference between old and new model single six?
