This is one problem that I never liked about hammer guns. When I first got my Ultra, I had a Simmons 3-9x40 installed for break-in and what not. This was the scope I had clearance issues with. When I put the spur onto the hammer, it would just nick the bottom of the scope. Well, with the $50 dollar Simmons, I almost knew that it would affect my POI when the scope was being banged every shot.
The simple fix I made was just putting higher rings on. Then I had plenty of clearance though the scope was a mile off the base.
After about two days, I took the Simmons off and mounted a Swift Premier 6-18X44 M669. Right now, the bell of the scope just clears the barrel making for a very nice fit. However, I have a ways to go yet on the objective hitting the hammer or hammer spur. It seems like the scope, rings, and base were made for the gun :grin: Plus the 18X really helps on popping g-hogs at extended ranges....
Good Shootin'
