SLx optics built Primary Arms’ reputation for innovation, reliability, and value.All SLx optics undergo rigorous field-testing during development to best serve the marksman in any environment.

The SLx 4.5-27x56mm FFP Rifle Scope brings high-magnification capability to the SLx lineup, offering excellent clarity and resolution at extended ranges.Its upgraded optical glass and multi-coated 56mm objective lens deliver bright, sharp images across the magnification range, making target identification and precision easier, even at distance.

With a first focal plane reticle, holdovers and ranging remain consistent at all zoom levels.Built to perform in the harshest environments, this scope features a rugged 34mm main tube and 32 MIL of elevation travel—ideal for long-range shooting.

The MIL turrets provide precise, tactile adjustments with excellent tracking, while the Easy Stop zero return makes dialing back to zero fast and intuitive.It’s shock-resistant, waterproof, and fog-proof, ready for hard use without compromise.

The ACSS DEKA G2 reticle is a MIL-based, precision crosshair design built for intuitive shooting across a wide range of distances.At its center is a fine 0.1 MIL dot, offering a clear, unobstructed point of aim ideal for precision shots at high magnification.

The reticle features clean MIL stadia with alternating hash marks in 0.1 and 0.2 MIL increments, extending out to 10 MILs in all directions.Integrated into the reticle is the target ranging system, allowing users to quickly estimate target distance using known height or width—from 300 to 1000 meters—without breaking position or shifting focus.

Designed for serious enthusiasts but priced within reach, the SLx 4.5-27x56mm blends premium features with rugged reliability.Every control is purposeful, every detail tested, and it’s backed by Primary Arms’ Lifetime Warranty—a testament to the confidence built into every optic they produce.
