Primary Arms SLx Compact 4-16X44mm FFP Rifle Scope - Illuminated ACSS-HUD-DMR-308/223 Reticle

This rifle scope is part of the Primary Arms Optics SLx® line. 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® 4-16x44mm 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® HUD DMR .308 reticle is a purpose-built DMR-style reticle, optimized for rapid and intuitive shooting with .308 Winchester and similar ballistic profiles. At the center is a precise chevron aiming point, surrounded by a bold horseshoe that enables fast target acquisition in close- to mid-range engagements. This reticle goes beyond traditional crosshairs by integrating an advanced ballistic drop compensation system, calibrated for ranges out to 1,000 yards. It features a built-in ranging ladder, moving target leads, and wind hold indicators—giving shooters the tools to engage confidently without needing to dial or reference external data. Designed for real-world utility, the HUD DMR delivers a complete firing solution in a single, easy-to-use sight aiming system.

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.
