I have a BSA red-dot that floats between a few of my pump guns.
I find they work pretty well for getting that first shot in the right area.
Can't really 'walk your fire' w/ a pump.
Plamer's Ghost Rings are great too....and no batteries!
Just a nice, basic, open ring to get your barrel lined up nice and quick.
Works better than any optic for a well placed snap shot.
Strive for that moment when you're only a slice of pizza and a hooker away from paradise.
