While red-dot optics have become incredibly popular for use on a range of firearms, there are issues with employing such an optic, particularly for shooters who have some level of astigmatism. A red dot, when viewed through astigmatic eyes, can appear like a broad streak or a blot, and no level of quality in a red-dot sight will fix this view. However, mounting a prism sight like the SLx 1x20 mm Prism Scope from Primary Arms will address this issue while providing many of the same benefits as a traditional red-dot sight.

“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.”

Both red and green reticles are available in the Primary Arms SLx Prism Scope lineup, and the optic is built with an enlarged eyebox that provides fast, easy viewing through the 1X lens. Combined with this is a 3.7" eye relief that allows shooters to stay back from the ocular lens and be more aware of their immediate surroundings.

Inside the Primary Arms SLx Prism Scope is a glass-etched reticle that can be used with or without battery illumination. There are 11 different illumination settings powered by a single CR2032 battery. On a mid-range setting, battery life can last up to 3,000 hours. All of this is packed inside a durable aluminum housing complete with a black, hard-anodized finish.

At the heart of the Primary Arms SLx Prism Scope is its ACSS Cyclops reticle, a patented design that offers several unique features. At the center of the reticle is a horseshoe-style design that allows for rapid target acquisition. Below that are helpful ranging icons. The width of the lines reflect the width of an 18" center-mass target at 200, 300 and 400 yards.

Suggested retail pricing on the Primary Arms SLx Prism Scope is $239.99. For more information, visit primaryarms.com.
