The PLx HTX-1 features a patent-pending chassis-based mounting system that is compatible with almost all existing optics-ready handguns. Unlike adapter plates, the modular chassis system is an integral part of the optic itself, providing a lower centerline and stronger mounting connection. The PLx HTX-1 also has the lowest centerline of any enclosed pistol reflex and co-witnesses with standard-height iron sights. This allows the HTX-1 to fit with a much broader selection of holsters and reduces the risk of snagging. It also greatly reduces height-over-bore issues.

In addition, the PLx HTX-1 features a rugged narrow-band glass doublet with a wide-band anti-reflective coating, resulting in a crystal-clear sight picture. It also has a proprietary AutoLive illumination technology and is available with an ACSS Vulcan Dot or standard 4 MOA dot reticle. SRP: $649.99. primaryarms.com
