Primary Arms SLx 3X MicroPrism is a compact 3× magnification prism sight from the renowned SLx line, celebrated for reliability, innovation, and excellent value. Field tests on a SCAR 17 .308 Win fired over 7,000 rounds without damage to the sight. The SLx 3x features an improved ACSS Raptor 5.56/.308 reticle etched on premium low-dispersion glass and a reinforced mounting base ensuring rigidity and reliable weapon attachment.

The SLx 3x prism sight allows easy target identification at medium distances and fast both-eyes-open shooting at close range. Astigmatic shooters often struggle with red dot sights, where the aiming point appears blurred or distorted, especially on small or distant targets. This can be solved by using a prism sight, holographic sight, or riflescope, which are gaining popularity abroad. Unlike red dots, prism sights with magnification feature BDC reticles and provide a much clearer parallax-free image. They also improve accuracy at longer ranges while enabling both-eyes-open aiming for full situational awareness.

The sight has a sealed aluminum body with an IP67 rating, making it resistant to fog, rain, and shock. Its large exit pupil and wide 69 mm eyebox allow quick target acquisition without precise alignment. This provides a wide field of view, ideal for dynamic shooting at moving targets. The proprietary ACSS Raptor 5.56/.308 reticle is etched on glass and visible at any time of day without illumination. Below the reticle is a metric scale for range estimation and shooting at varying distances. The green-illuminated reticle (horseshoe and chevron) has 13 daytime brightness levels and 3 night vision-compatible settings. The AutoLive motion sensor extends battery life — up to 29,000 hours at medium brightness. After prolonged inactivity, AutoLive automatically turns off the illumination, instantly restoring it when the weapon is moved.

The ACSS Raptor is calibrated for 5.56/.308 ballistics. The central reticle features a thin chevron (inverted V) surrounded by a thicker horseshoe, with a range-estimation scale below the chevron for precise targeting at various distances. This intuitive reticle is perfect for dynamic short-range shooting and precise medium-range engagements. ACSS is a simple yet functional aiming system appreciated by both novice and experienced shooters worldwide. Measurements are in meters, making the reticle easier to use.

The Primary Arms SLx 3X MicroPrism has a robust aluminum mount with key steel components, ensuring stable zero retention. Additional risers are available to mount the sight at the desired height in up to 8 configurations.
