Why This Light Wins for Varmint Hunters
Having tested lights from the Spring TX CNC floor to the Arizona desert, the Primos hits the sweet spot between price and performance. That 300-yard beam isn’t marketing fluff – I’ve verified it on our 100-yard range (and beyond) with consistent illumination on coyote-sized targets. The LED maintains zero better than most red dots I’ve used.
Key Features

- Weather-resistant housing – Handled West Texas dust storms without flickering
