Parallax is good and overall quality appears top notch. All perform flawlessly. Not a deal breaker for the price.

The qd mount, while not of the locking variety, sits very tight on the rail and flush with the sight and weapon. Elevation/windage corrections screws are recessed slightly into the sight body to prevent inadvertent change.

Since i honestly can not believe there are people out there with firearms who think out the box throw reticle has nv night vision.

Probably would make no difference in hight light situations. If you sight this in and move your leaver to change optics it will no longer be sighted in. The nv function does not work.

They're a perfect fit and give an amazingly crisp sight picture. Easily installs with a sight pusher tool.

Excellent no frills sight. Great price. Wishes i had upgraded sooner. Nice bright sights. Better than my glock with oem night sights.

Each dot illuminates perfectly in low light. Just the right amount of brightness at night. Excellent visual sights recognition in both daylight and darkness.

Tritium is dead. Arrived extremely dim and with almost no tritium glow left. Their either old & outdated or defective sights.
