Rather than a scope, have youn looked at the Tru-Glow sights...they are awesome...I was going to mount a scope on my 870 pump gun for turkey & deer till I ws steered to the Tru-Glow sites....they are excellent in very low light conditions unlike a scope & one hell of a lot cheaper....I have them mounted on both my turkey & slug barrel....just my .02 cents worth....Brampton Mike
