Prism Device Primary Arms SLx 3x Micro Prism iR Green ACSS Raptor 7.62x39/.300 AAC Yard

SLx prism devices combine the quick target acquisition of a red dot sight, the precision of an optical scope, and a compact design. Therefore, they are popular not only among users with astigmatism but also among shooters seeking a versatile device for short- and mid-range shooting.

The American brand Primary Arms, known for its high-quality optics, red dot sights, prism devices, and shooting accessories, has rapidly conquered the U.S. market by offering products with an excellent price-to-performance ratio. Most items come with a lifetime warranty, underscoring the manufacturer’s confidence in its products. Primary Arms is also famous for its proprietary ACSS reticle, which helps beginner shooters quickly improve their shooting skills.

Primary Arms SLx 3X MicroPrism is a compact 3× magnification prism device from the renowned SLx series, celebrated for its reliability, innovation, and outstanding value. During field tests, Primary Arms optics were tested on a SCAR 17 .308 Win rifle, firing over 7000 rounds without damage. The SLx 3x model features an improved ACSS Raptor 5.56/.308 reticle etched on premium low-dispersion glass and a reinforced mounting base for rigidity and durability.

Primary Arms SLx 3x offers easy target identification at medium range and fast both-eyes-open shooting at close range. Many shooters struggle with astigmatism, a vision defect that causes the aiming point in red dot sights to appear blurred or distorted. This makes precision shooting difficult, especially at long distances. The problem can be solved with an expensive holographic sight, a variable-power scope, or an increasingly popular prism device. Unlike red dots, prism devices with magnification have a BDC reticle, a sharper image free from parallax error, and better long-range precision, while still allowing both-eyes-open shooting.

The device features a sealed aluminum housing with IP67 protection, ensuring resistance to fog, moisture, rain, and shock. A large exit pupil and spacious eyebox (69 mm) enable rapid target acquisition without perfect eye alignment. This makes it ideal for dynamic shooting at moving targets. The proprietary ACSS 7.62/.300BLK reticle is etched on glass and visible even without illumination. Below the main aiming point is a metric scale for range estimation and ballistic holdovers. The illuminated elements (horseshoe and chevron) offer 13 daylight and 3 night-vision levels. The AutoLive motion sensor extends battery life — up to 29 000 hours on medium brightness. After inactivity, illumination turns off automatically and reactivates instantly when the weapon moves.

The ACSS Raptor is a proprietary Primary Arms reticle calibrated for 7.62/.300BLK ballistics. It features a thin central chevron (inverted V) surrounded by a horseshoe, with range and holdover markings below. This intuitive reticle excels in close-range dynamic and medium-range precision shooting. ACSS is a simple yet versatile aiming system valued by shooters worldwide. The markings are in meters for ease of use.

The Primary Arms SLx 3X MicroPrism includes a robust aluminum mount with key steel components for secure zero retention. Optional risers allow up to 8 mounting height configurations.
