As part of Discovery 2025, Primary Arms Optics unveiled the NEW PLx® HTX-1, the company’s first-ever Made-in-USA optic. This enclosed-emitter reflex sight combines advanced materials, innovative engineering, and modern manufacturing techniques to set a new standard for American pistol optics.
The HTX-1 is part of Primary Arms Optics’ flagship PLx® Tier, known for delivering the highest levels of precision and performance. As Primary Arms’ inaugural domestically produced optic, the HTX-1 represents a significant milestone in the company’s product capabilities, while reinforcing its commitment to quality and reliability.
“HTX-1 is the result of a three-year journey to expand optics manufacturing in the United States.
This project exemplifies our commitment to innovation and craftsmanship, delivering a truly American-made optic designed and built in Houston, Texas.”
Marshall Lerner, Founder and CEO of Primary Arms Optics
Unique in its design, the PLx HTX-1 features a patent-pending modular chassis mounting system, which ensures compatibility with nearly all optics-ready handguns. Unlike traditional adapter plates, this integrated system creates a stronger connection and a much lower optic centerline, enabling co-witness with standard-height iron sights. This design minimizes height-over-bore while improving holster compatibility.
Designed for the toughest conditions, the HTX-1 features a 7075 Aluminum housing with reinforced contours and a recessed lens pocket to guard against drops, impacts, and debris. Potted electronics and Grade 12.9 hardware ensure reliable performance under shock, vibration, and heavy recoil. The optic features narrow-band glass doublet lenses treated with wide-band anti-reflective coatings, which provides a clear, undistorted sight picture in any environment.
At release, the HTX-1 is available with two reticle options: ACSS® Vulcan® Dot with a toggleable outer ring for rapid target acquisition, or a 4 MOA dot reticle. The sight is powered by a side-loading CR2032 battery and features AutoLive® illumination technology, which conserves battery life when the optic is not in use.
The PLx HTX-1 is a significant milestone for Primary Arms Optics, reflecting years of research, development, and investment in American manufacturing. Its introduction also strengthens the company’s growing PLx® product line, which serves professional marksmen, law enforcement, and dedicated shooting enthusiasts with premium optics designed to excel in demanding environments.
