Works and looks great!
I thought I’m going to have a problem when installing the sight to my bcm upper because it seems too tight, but with a little bit of encouragement with a rubber mallet, it went through.
Great price very very very quick shipping. A pleasure to do business with a company like this one.
These sights do what they're supposed to do. Never had a problem with any of them and at this price it's hard to beat.
Excellent sight. Easy install. Delivered fast and secure.
Installed perfect and has all the tools needed to adjust. Love it...
Great sale price, shipping was expedient.
