All my cylinders holes match the reg, perhaps they've changed?
You could to make a spanner for the reg, a bit of metal with 3 holes in it & 2 pins should be easy to make.
Failing that remove the barrel - the locking collar only needs slacking off half a turn & then the barrel unscrews.
When replacing it the barrel's position adjusts the mag fit,
