The "fits 44mm" probably refers to this.
This is true and the old rings did not come with this listing. I have find these listings to be very helpful, up front. ...
Now, your scope will probably not clear the barrel or whatever in on it. I once had a set of rings where the front bell, cleared the barrel but not the rear sight and on another occasion, the bell again, cleared the barrel but had to trim my scope caps. Go figure !!! ...
Be Safe !!!
