Enlarger Primary Arms SLx 3x Micro FDE

The American brand Primary Arms, renowned for high-quality magnifiers for red dot and prism devices and for shooting accessories, rapidly captured the US market by offering products with an excellent price-to-performance ratio. Most products from the brand come with a lifetime warranty, underscoring confidence in their offerings. Primary Arms is also famous for its proprietary ACSS reticle, which helps novice shooters quickly improve 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 tests, Primary Arms optics were mounted on a SCAR 17 .308 Win and fired over 7,000 rounds without damage to the optics.

Primary Arms SLx 3x is a micro magnifier with 3× magnification that enables immediate 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 the electro-optical device (red dot, holo, or prism), enlarging the target image so it can be better identified and accurately engaged.

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 ranges but also compensates for the main weakness of red dot/holographic devices — difficulty delivering precise fire at extended distances.

The ability to rapidly 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 regularly use true 1× magnification provided by a red dot/holo device but want to magnify a distant target 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 have a fixed 3× magnification and provide a wide field of view of 11.7 m / 100 m. 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 good-quality optics with multi-layer coatings, significantly improving contrast and light transmission for excellent image quality.
