I have claws on 4 and one unscoped...getting another unscoped, also. Both my cape guns are scoped in claws. The 12/8x57jr J.P. Sauer cape gun had claw bases when I got it, but the scope was long gone. Lee LeBas installed a new front base and ring, and made up a ring for the rear base. He had to mill out the rib a bit for the new front base. The gun shot the same as before...1" at 1 O'clock at 60 yards with S&B 196 gr ammo. By the way, the S&B ammo in 8x57jr and jrs, and in 9,3x74r regulate very well in my older guns FYI.

All the others had scopes already on them when I got them, and all shoot well with the flip blade. The Tribbel and Charles Daley/Sauer sidelock-sidecock both have tang peep sights, as well as blades.

The drillings seem to take to messing around with the top rib better than do cape guns from what I've seen. I think it may have to do with the fact that the RIFLE barrel is well below the two shotgun barrels, and the whole set up is extremely rigid.
