Primary Arms SLx 3X MicroPrism is a compact 3× prismatic device in the renowned SLx line, valued for reliability, innovation, and affordability. During field testing, Primary Arms optics withstood over 7,000 rounds fired from SCAR 17 (.308 Win) with no issues. The SLx 3x model features an enhanced ACSS Raptor 7.62/.300 reticle etched on low-dispersion glass and a reinforced mounting base ensuring rigidity and durability.

The SLx 3x device allows easy target identification at mid-range and fast both-eyes-open shooting at close range. Many shooters with astigmatism experience blurred or distorted red dots; this can be solved by using a prismatic device that delivers a sharp, parallax-free image with a BDC reticle for precision. Such devices allow situational awareness while maintaining accuracy.

The device has a sealed aluminum body with IP67 protection, making it resistant to fog, moisture, and impact. Its large 69 mm eye relief allows rapid aiming without perfect optical alignment. The ACSS 7.62/.300BLK reticle is etched in glass and remains visible even without illumination. The red illumination (horseshoe + chevron) offers 13 daylight and 3 NV settings. The AutoLive motion sensor extends battery life to up to 29,000 hours by shutting off illumination during inactivity and instantly reactivating it upon movement.

The ACSS Raptor reticle is designed for 7.62/.300BLK ballistics. Its thin central chevron (inverted “V”) is surrounded by a horseshoe, with a range-finding scale below — intuitive for dynamic short-range and precision mid-range shooting. The scale is metric for user convenience.

The Primary Arms SLx 3X MicroPrism features a durable aluminum mount with steel reinforcements for stable zero retention. Optional risers are available, allowing height adjustment in up to 8 configurations.
