Magnifier Primary Arms SLx 3x Micro w/ACSS Pegasus Ranging Reticle FDE

The American brand Primary Arms, renowned for its high-quality magnifiers for collimator and prismatic devices as well as shooting accessories, has rapidly conquered the U.S. market by offering products with an exceptional price-to-quality ratio. Most of its products come with a lifetime warranty, emphasizing the manufacturer’s confidence in their reliability. Primary Arms is also known for its proprietary ACSS reticle, which helps beginner shooters quickly improve their marksmanship skills.

The SLx FS 3x Micro ACSS Pegasus magnifier belongs to the Primary Arms SLx optics line, whose outstanding reputation is built on three core principles: reliability, innovation, and unbeatable value for money. During field testing, Primary Arms optics were mounted on a SCAR 17 (.308 Win) rifle and successfully withstood over 7000 rounds without damage.

The Primary Arms SLx 3x ACSS Pegasus is a micro magnifier with 3× magnification that allows the rifle to be instantly prepared for long-distance shooting. It features extended eye relief, a wider field of view, improved light transmission, and the innovative ACSS Pegasus reticle, which serves as an analog rangefinder.

The magnifier is compatible with collimator, prismatic, and holographic devices. Mounted behind an electro-optical device (such as a collimator, holographic, or prismatic sight), it enlarges the target image, allowing for better identification and more precise engagement.

Primary Arms SLx 3x Micro ACSS Pegasus — magnifier with analog rangefinder function

SLx 3x Micro is the first magnifier featuring the ACSS Pegasus reticle designed specifically for shooting magnifiers.

While most magnifiers merely enlarge the reticle of the main optic, the ACSS Pegasus is an etched-glass reticle that serves as a highly functional aiming tool, enabling rapid range estimation of silhouette targets and larger objects such as vehicles, using a milradian-based scale.

The ACSS Pegasus allows shooters to estimate range based on the average human height (177 cm), shoulder width (71 cm), or mil-based markings (requiring conversion). Its subtle design integrates seamlessly with optical reticles, and the intuitive layout enables precise distance assessment within seconds.

Primary Arms SLx 3x not only enhances accuracy at longer distances but also compensates for the main limitation of collimator or holographic devices — difficulty in maintaining precision at extended ranges.

The ability to instantly adapt the rifle for long-range targets, combined with the relatively low cost (compared to full rifle scopes), makes magnifiers increasingly popular among sport shooters, soldiers, and hunters. This is a convenient and efficient solution for those who use 1× collimators or holographic devices but want the option to quickly zoom in on distant targets.

The housing is made of anodized aircraft-grade aluminum, providing excellent resistance to impact and corrosion. The tube is nitrogen-purged and fully sealed, protecting the optics from fogging, weather, and recoil. A rubber armor further increases resistance to mechanical damage.

The optics offer fixed 3× magnification with a wide 11.7/100 m field of view. The image can be adjusted vertically and horizontally and finely focused via a diopter. The adjustment screws are recessed into the body, keeping the view unobstructed. High-quality multilayer-coated lenses provide enhanced contrast and light transmission for a bright and clear image.
