Description
The Primary Arms HTX-1 Red Dot is a game-changing enclosed emitter sight, meticulously designed and made in Houston, Texas, for unmatched precision and reliability. It’s one of the only enclosed red dots that allows you to co-witness with standard-height iron sights on your Glock MOS—no need to invest in taller sights. (Note: This optic will not fit the Glock 43X/48 MOS.)
Crafted with durable 7075 T6 aluminum housing and a steel mounting plate, the HTX-1 is built to withstand the harshest conditions. Its unique mounting system, a patent-pending Modular Chassis System (MCS), ensures a secure and tight fitment on a variety of platforms, including RMR slides with raised ZEV posts. The USA-made screws further reinforce its exceptional build quality.
This red dot features Autolive motion-sensing technology, which powers on the reticle when the optic detects movement, conserving its 20,000-hour battery life. The side-loading battery tray allows quick and easy battery changes without removing the optic, ensuring uninterrupted performance.
