Good sight. Buy loctite.
So far I really like this optic, only complaint is the mount will come loos after a hundred rounds or so. Definitely buy some blue loctite for installation. The features this optic offers are fantastic for the money would definitely like to see them include a retention bolt with loctite applied or a mini pack to prevent this from losing zero or worst case falling off. If this were changed I would consider 5 stars.

Good looking product.
Haven’t zeroed the sight yet but appears to
be just what I wanted.

Perfect sight for an AR Pistol
Visibility of the reticle is amazing with the Green dot. Red dots have always been difficult for me to see but the green is crystal clear. Extremely bright even when shooting in direct sun light on a white paper target. The shake awake feature is instant with the slightest movement. Auto brightness adjustment works pretty well but is easy to change of you desire brighter or darker.
