Worth the money - BSA Optics Huntsman Illuminated 20mm Red Dot Sight

Mine came as a a package deal with a Mossberg 715t flat-top .22 rifle. It has worked better than I expected. It held it's zero even after the rifle it's attached to fell out of the back of my truck. It has plenty of brightness settings for most lighting conditions. The glass isn't exactly camera quality, but for plinking and protecting my chickens from stray dogs, etc. this red dot works just fine.
Pros: 3/8 dovetail or 5/8 weaver rail mounting system\holds zero
Cons: didn't come with an allen wrench for the mount
