I bought one (3x9 40mm) for my Rem 870 12 gauge with rifled slug barrel. It was on sale at Bass Pro for I think $30 bucks. I expected to use it for one, maybe two seasons. I have to say it's been well worth $30.
It's a tough scope too, embarrassing as it is, I dropped it from my 12ft tree stand last year. When I checked the zero, it was still dead on!
For deer size game out to 125yrds it is clear and has been a good scope for me. Never thought I would have it on the gun for five seasons.
