Magnifier Primary Arms SLx 3x Micro

The American brand Primary Arms, renowned for high-quality magnifiers for red dot and prism devices as well as shooting accessories, rapidly gained traction in the U.S. market by offering products with an excellent price-to-performance ratio. Most products from the brand are covered by a lifetime warranty, which underscores confidence in their quality. Primary Arms is also famous for its proprietary ACSS reticle, which helps beginner shooters quickly improve their marksmanship.

The SLx FS 3x Micro magnifier belongs to the Primary Arms SLx optics line, whose strong reputation is built on three pillars: reliability, innovation, and unbeatable value. In field testing, Primary Arms optics were mounted on a SCAR 17 (.308 Win) and withstood over 7,000 rounds without damage to the optics.

Primary Arms SLx 3x is a micro magnifier with 3× magnification that enables instant preparation of a rifle for longer-range shooting. The magnifier features increased eye relief (Long Relief), a wider field of view, improved light transmission, and a robust aluminum body resistant to recoil and harsh environmental conditions.

The magnifier is compatible with red dot devices, prism devices, and holographic devices. It is mounted behind an electro-optical device (red dot, holo, or prism), enlarging the target image so it can be better identified and engaged accurately.

Primary Arms SLx 3x Micro — high-quality magnifiers for red dot and prism devices

The Primary Arms SLx 3x not only increases shot accuracy at longer distances but also compensates for the main limitation of red dot/holographic devices — difficulty delivering precise fire at extended ranges.

The ability to quickly adapt a rifle for distant targets, combined with the relatively low cost of a magnifier (compared to a rifle scope), has made magnifiers increasingly popular among sport shooters, soldiers, and hunters. A magnifier is a convenient and effective solution for shooters who rely on true 1× magnification from a red dot/holo device but want to zoom in on distant targets on demand.

The device body is made from aviation-grade anodized aluminum with high resistance to shocks and corrosion. The tube is nitrogen-filled and thoroughly sealed, making the optics resistant to fogging (internal condensation), weather, and recoil. A rubberized armor protects the magnifier body, increasing its resistance to mechanical damage.

The optics provide fixed 3× magnification and a wide 11.7 m / 100 m field of view. The image can be adjusted vertically and horizontally and finely focused using the diopter. Adjustment screws are discreetly recessed into the tube so they do not obstruct the view. The device uses high-quality multi-coated optics, significantly improving contrast and light transmission for excellent image quality.
