Primary Arms 3x MicroPrism Review

Introduction & Price

The Primary Arms SLx 3X MicroPrism Scope with Green Illuminated ACSS Raptor Reticle is a compact, durable optic designed for precise shooting. This prism scope combines the size of a microdot with the clarity and magnification of a 3x optic. It features 13 illumination settings, including three night vision-compatible options, and uses AutoLive motion-sensing technology to conserve battery life. The etched reticle is ideal for those with astigmatism, and the optic provides a wide field of view and forgiving eye relief. It includes multiple mounting options and is optimized for 5.56 and .308 cartridges​ (Primary Arms)​.

This optic sells for $319.99, which is much less than an EOTech HWS or an LPVO from a top tier manufacturer. We compared it to a cheap Burris red dot, an EOTech and a Trijicon Credo LPVO.

The PA SLx 3X MicroPrism takes a little more effort to acquire the reticle compared to an EOTech HWS when raising your rifle from the ready position. However, anybody with an astigmatism will attest to the “blooming” reticles on EOTech HWS optics. There is no such problem with the PA MP.

With regards to an LPVO, the PA MP drops significant weight and is a fraction of the cost of a top tier LPVO such as a Trijicon.

Design & Build Quality

The SLx 3X MicroPrism is compact, weighing under 8 ounces and measuring just 2.95 inches in length. Despite its small size, it is built to withstand heavy use and adverse conditions, featuring a ruggedized mounting system with multiple height configurations. The construction of the optic is sleek and durable, ensuring it can endure the rigors of field use.

Optical Performance

The SLx 3X MicroPrism delivers exceptional clarity with its crystal-clear glass, providing a 3x magnification that enhances target acquisition and precision at a distance. The wide field of view (38 feet at 100 yards) and forgiving eye relief (2.7 inches claimed, it’s more like 4″ to 5″) make it suitable for both close-quarters and long-range engagements. The etched reticle, illuminated in green, remains crisp and clear without illumination, making it an excellent choice for users with astigmatism.

Reticle & Illumination

The ACSS Raptor reticle is the highlight of this optic. It features a green illuminated reticle with 13 brightness settings, including three night vision-compatible levels. The outer horseshoe enhances target acquisition speed for close-quarters shooting, while the center chevron provides a precise aiming point for longer shots.

The reticle also includes ballistic holdovers for 5.56 and .308 cartridges in 100-yard increments, along with wind holds for 5 and 10 mph crosswinds.

Battery Life and Technology

One of the standout features of the SLx 3X MicroPrism is its AutoLive motion-sensing technology, which helps conserve battery life by turning off the illumination when no motion is detected and reactivating it when movement is sensed. The optic is powered by a single CR2032 battery, providing up to 29,000 hours of runtime on medium settings, ensuring that it is always ready when needed.

Mounting and Compatibility

The optic comes with a versatile mounting system that allows for eight different height configurations, ensuring compatibility with a wide range of rifle setups. The industry-standard mini-prism mount footprint guarantees that the SLx 3X MicroPrism can be securely attached to most rifle platforms, providing a stable and reliable shooting experience.
User Experience

The optic’s small size and weight make it a great choice if you’re looking to reduce the overall weight of your rifle without sacrificing performance. The clarity of the glass and the sharpness of the reticle, even in bright daylight conditions, is outstanding.

Conclusion

The Primary Arms SLx 3X MicroPrism Scope with Green Illuminated ACSS Raptor Reticle is an excellent choice for shooters looking for a compact, durable, and precise optic.

Its combination of innovative features, such as the AutoLive motion-sensing technology, etched reticle, and versatile mounting options, make it a versatile and reliable addition to any rifle setup.

Whether you are engaging targets at close range or at a distance, this optic delivers exceptional performance and value. At $319.99.
