Primary Arms SLx 3x MicroPrism Sight

This MicroPrism is part of our SLx optics line. SLx optics built our reputation for innovation, reliability and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.

The SLx 3x MicroPrism is an all-new advanced optical system that combines the compact, lightweight size of a microdot with the durability and precision of a 3x magnified optic. The SLx 3x MicroPrism offers 13 illumination settings with AutoLive® motion-sensing on/off technology and multiple night vision compatibility options.

Weighing under 8oz, the SLx 3x MicroPrism is smaller and lighter than many red dot sights, though its crystal-clear glass and 3x magnification offer improved precision at distance. Even in close-quarters, the optic’s wide field-of-view and forgiving eye relief make it easy to snap on target.

Because the SLx 3x MicroPrism uses an etched reticle with adjustable diopter, the user will always have a clear, crisp reticle image, even if they have severe astigmatism. When set to max illumination, the MicroPrism reticle is fully daylight bright. For low-light, this optic offers 3 different NV-compatible settings, accommodating any ambient light level. Paired with our AutoLive® motion-sensing illumination technology, this optic provides an exceptionally long runtime at any brightness setting.

This package also includes our new ruggedized mounting system with industry standard mini-prism footprint, guaranteeing reliability and zero retention through heavy use and adverse conditions. Out of the box, this mount can be set for 8 different mounting heights and configurations, ensuring compatibility with any rifle system.

The Advanced Combined Sighting System (ACSS®) is a high-performance reticle solution to the challenges of modern marksmanship, distilling complex mathematics into intuitive holdovers that enhance your speed and precision. Each ACSS reticle is specially designed to outperform in real-world applications, incorporating a mix of tools to deliver instant firing solutions. These tools may include ballistic drop compensation, auto-ranging stadia, wind holds, moving target leads, or an infinitely-precise center chevron.

ACSS-Raptor-5.56/.308-YP Reticle
Optimized for our SLx MicroPrism, the ACSS-Raptor5.56/.308-YP reticle adopts the features of our beloved ACSS Raptor reticle to a prismatic optic design. The brightly illuminated outer horseshoe improves acquisition speed for close-quarters shooting, while the center chevron acts as an infinitely precise aiming point for enhanced accuracy. This reticle also includes auto-ranging ballistic holdovers for 5.56, .308, and similar cartridges in 100-yard increments with included 5-mph and 10-mph crosswind holds.

ACSS-RAPTOR-7.62x39/300BO-YP Reticle
The ACSS-RAPTOR-7.62x39/300BO-YP brings the same features as our 5.56/.308 reticle, except the holdovers match 7.62x39 and .300 AAC Blackout ballistics. At close range, users can rely on the bold outer horseshoe and infinitely precise center chevron for fast and accurate target acquisition. As range increases, users can use the auto-ranging ballistic holdovers and accompanying 5-mph and 10-mph wind holds, which are set in 100-yard increments.
