Are these 30mm rings 37mm high to give me absolute co-witness on my Benjamin Bulldog .357 ?
The overall height (from the base of the mounting surface to the top of the ring is 52mm. To the center of the scope ring would be 37mm, so yes.
Can anyone tell me if these will work with my Hatsan bt65?
They should fit the weaver rail portion
What is the saddle height of the high quick disconnect UTG scope rings in 30 mm?
What does the description mean that it fits Weaver/Picatinny rail? I thought that Weaver was one type and Picatinny was another type, and they require different mounts???? Or is it saying that the Picatinny is a Weaver product?
In airgunning they are interchangeable
can the width of the lock be adjusted
No, it's designed to hook to a standard weaver.
