Just bought a Mk II F. All I've done with it so far is 25 yd target for testing that comes in the book that came with the gun. I noticed my shots are hitting 2-3 inches to the right so have to adjust my front sight. That's where an issue comes up, the front sight is so tight that it will not budge no matter what I try to do with it. Been looking around at scope mounts and all that I could find that they say fits it is the weaver #24 2 piece mount (which no local shops keep in stock so I have to order from midway). Are there any other mounts the fit the Mk II F? Is there anything I could do to break that front sight free short of taking it to a gunshop, I would like to put a set of high rings on it so I can use my irons from time to time.
