Now for the bad news - NcStar Tactical Red/Green/Blue Dot Sight w/ Cantilever Weaver Mount

I gave this unit a 5 star rating after I first received it. All seemed fine until I pulled out the AR the other day to adjust the dot to the BUIS. I could not get the dot to move any further left than around center. It moves to the right but it cannot be centered left of center scope. NcStar does have a lifetime warranty on optics but you have to give them $10 if you want to send it in more than 90 days after purchase. Not worth investing another ten bucks in a defective red dot. Guess I will just keep the mount and learn my lesson about "affordable" red dot optics.
Pros: Cantilever mount is well built and looks good
Cons: Windage adjustment failed
