The Primary Arms SLx 3x MicroPrism.

Although microdots are great for close quarters, typically a separate magnifier is needed to reach out at distance. However, the new SLx 3x Microprism from Primary Arms shows that doesn’t have to be the case. And it does it at a budget friendly price.

Housed in a lightweight 7.95-ounce housing, the SLx 3x is smaller than many red dot sights. However, the crystal-clear glass and 3x magnification are ready for improved accuracy at any distance. The optic’s wide field-of-view and forgiving eye relief also make it easy to snap on target in close-quarters.

Utilizing an etched reticle with adjustable diopter, the SLx 3x provides a clear, crisp image, even if the user has a sever astigmatism. With 13 illumination settings, the optic provides full daylight brightness when set to max illumination. Likewise, 3 different night-vision-compatible settings accommodate any ambient light level.

Powered by a CR2032 3V Lithium Coin battery, the SLx 3x uses AutoLive motion-sensing on/off technology to preserve battery life. Similarly, a low power sleep mode extends runtime for “always-on” storage.

The SLx 3x ships with Primary Arms’ new ruggedized mounting system, with industry standard mini-prism footprint. As a result, the sight promises reliability and zero retention under heavy use and adverse conditions. There are 8 different possible mounting heights and configurations with the mount, right out of the box.

“The SLx 3x MicroPrism is one of our most exciting new optics of 2022, bringing the precision of a 3x prism with the form factor of our proven microprism design,” says Stephen Morgan, Primary Arms Optics’ Director of Product Marketing. “At only 8 oz overall weight, this optic is no heavier than your average red dot, yet it offers the enhanced range and accuracy potential of a magnified optic. It’s the perfect choice for any general-purpose carbine.”


The Primary Arms SLx 3x MicroPrism is available for pre-order with an MSRP of $299.99. For more info, please visit
