Primary Arms SLX 3X MicroPrism: A Comprehensive Review
The Primary Arms SLX 3X MicroPrism stands out in the realm of optical sights, particularly for its combination of compact size and effective magnification. This review delves into its features, performance, and usability, providing essential insights for potential users.
Overview of the MicroPrism
At first glance, the MicroPrism resembles conventional compact red dot sights, such as the Aimpoint T-2, but with added capabilities. Weighing only eight ounces, it’s remarkably lightweight given its 3X magnification, making it a practical choice for a variety of firearms, including AR-platform rifles.
Optical Features and Design
The design boasts versatility with various reticle options, including ballistic drop compensation (BDC) reticles suited for calibers such as 5.56 and .308. Users can choose between illuminated reticles in red or green, enhancing low-light visibility. Notably, the MicroPrism employs a shake-awake technology dubbed AutoLive, automatically activating the illuminated reticle upon motion while conserving battery life.
Field of View and Eye Relief
With a field of view of 38 feet at 100 yards, the MicroPrism provides adequate visibility for most engagements. Eye relief is measured at 2.7 inches, a standard range for prism optics, although it can feel somewhat limiting compared to other sight options.
Mounting and Zeroing
Utilizing the mini ACOG footprint, the MicroPrism features an adjustable mount, allowing for customizable positioning on the rail to accommodate user preference and comfort. During testing, zeroing the optic was methodical but straightforward, requiring adjustments primarily at 100 yards to optimize performance with the chosen ammunition.
Precision and Adjustability
The elevation and windage turrets are designed for intuitive adjustments, offering .25 MOA per click. Users praised the tactile feedback of the turrets, which provide distinct clicks without overlap, facilitating accurate sighting adjustments.
Testing on the Range
Field tests revealed the MicroPrism’s ability to perform effectively at varying distances. It provided clear visuals at 200 yards, with satisfactory clarity for target identification, although some minor chromatic aberration was observed.
Close-Quarter Engagement
While fixed magnification optics can present challenges for close-range engagements, the MicroPrism managed adequately at distances as close as three yards. Although the illumination required higher brightness, it remained functional during drills.
Performance Summary
In performance assessments, the MicroPrism demonstrated versatility for various shooting applications, particularly within the 50-200 yard range. Users successfully executed multiple drills, showcasing the optic’s ability to deliver precision with a simplified aiming process.
Conclusion
The Primary Arms SLX 3X MicroPrism is positioned as a highly practical choice for shooters seeking an affordable option without compromising on quality. Retailing for under 400 dollars, it caters to a broad spectrum of firearm enthusiasts looking for reliable performance in a compact form. Overall, while some aspects may not excel in every scenario, the balance of functionality and size makes it a noteworthy option for general-purpose use.
