I have an 870 express Mag. and I decided to put a scope on it.

I used a weaver saddle mount which is surprisingly rock solid, no movement at all. I have shot all kinds of 3" loads including slugs and my scope is still dead on.

I followed the mounting instructions to a T.

But my problem is I can see the barrel of the gun when I look through the Turglo gobble stopper scope. It is visible at the bottom and I can see about 8" or so of it.

Is that normal?
