Primary Arms Optics PLx HTX-1 American-Made Enclosed Pistol Optic with Modular Chassis System

HOUSTON, TEXAS — 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.
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. Read more
