The SLx 4-16x44mm FFP Rifle Scope extends the trusted SLx optic line into the mid-power precision space, delivering a versatile magnification range in a surprisingly compact footprint.At just 10.1 inches in length, this scope is purpose-built for agile, low-profile setups—ideal for designated marksman rifles, hunting carbines, or compact bolt guns.

Its streamlined form factor doesn’t come at the cost of performance, making it an excellent option for shooters who demand long-range capability without adding bulk.At the heart of this optic is a First Focal Plane (FFP) optical system, ensuring consistent subtensions and accurate holdovers at any magnification.

Paired with high-performance optical glass, the 44mm objective lens delivers excellent light transmission and clarity across a wide field of view.The eye box is forgiving and comfortable, allowing for quick target acquisition and positive engagement in both fast-paced and precision-focused shooting scenarios.

An adjustable parallax (from 10 yards to infinity) further refines clarity and accuracy at all distances.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 our 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.Built to Primary Arms' rigorous SLx standards, this scope is shockproof, waterproof, and fog-resistant, with internals tested through extensive live-fire use.

Backed by an industry-leading Lifetime Warranty, the SLx 4-16x44mm FFP gives dependable performance and refined capabilities, whether for hunting, competition, or basic marksmanship.
