Primary Arms has announced the PLX HTX-1, an enclosed-emitter reflex sight that seeks to set a new standard for American-made optics. Yes, this is the first completely American-made Primary Arms optic produced in the company’s home base of Houston, Texas. While setting new standards is a tall order, Primary Arms has given me reason to believe for years, and the HTX-1 is looking really good on paper, with features I find particularly desirable.
