First Look: Primary Arms SLx 1X Optic with Green-Illuminated Reticle

posted on December 26, 2020

The popular SLx 1X prism optic from Primary Arms is now available with a green-illuminated reticle. As part of the SLx line of optics, the sight undergoes rigorous field-testing during development in order to continue Primary Arms’ reputation for innovation, reliability and value and to perform optimally in any environment. The SLx 1x20 Prism Scope with ACSS Cyclops reticle is a popular choice for a low-magnification prism scope, giving you the performance of a red-dot or reflex sight with an etched reticle that eliminates astigmatic distortion. 

“We’re happy to bring a green-illuminated ACSS Cyclops reticle for fans of our SLx 1X prism,” says Terry Mears, Primary Arms’ Director of Product Marketing. “Over the last few years, we’ve seen a huge increase in demand for optics with green illumination, and our SLx 1X prism was the perfect platform for the technology.”

The SLx 1x20 prism scope with ACSS Cyclops reticle has been a best seller for Primary Arms. The large eyebox, compact body, and 9.7-ounce weight of the prism optic mimics the speed and agility of red-dot and holographic optics, and yet still provides the user with an etched ACSS reticle that is usable without batteries and does not blur with an astigmatism. 

The new illumination option allows customers to choose between either a red or green reticle depending on their preferences. The green illumination stands out against warm-colored environments such as the desert sands and is easier to pick up in daylight conditions. Red reticles are excellent for heavily-vegetated areas and work well with lower-light conditions. Both color options come with 11 brightness settings and up to 3,000 hours of battery life on medium settings with a standard CR2032 battery.

MSRP for SLx 1x20 prism scope with ACSS Cyclops and green reticle is $239.99. For more information on this optic and other gear from Primary Arms, please visit
