RE: Shotgun Scopes
I use B Square rings and they're great. B Square makes great rings and mounts, and if your gun isn't tapped you should check out their website. To the best of my knowledge, B Square does not make scopes. I'm sure they farm this job out, and I would be cautious. The mount and ring set-up pictured in this add sells for $50.00 or more I think without the scope, so the scope is sure to be junk.
I just bought a Pentax Lightseeker 2-7x for $168.00 on ebay, brand new and half retail price! Ebay might be worth a look.
As far as retail, hard to beat the Nikon Prostaff shotgun scope for $130.00...fogproof, shockproof, great optics, and a LIFETIME WARRANTY! Spend the extra few bucks and you won't have to worry.
