Primary Arms SLx 4.5-27x56mm FFP Rifle Scope - Illuminated ACSS Athena BPR MIL 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® 4.5-27x56mm 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 your zero fast and intuitive. It’s shock-resistant, waterproof, and fog-proof, ready for hard use without compromise.

The ACSS® Athena BPR MIL reticle is a purpose-built MIL-GRID style reticle, designed for extreme precision at extended distances. Unlike traditional crosshairs, it uses a chevron tip at the center aiming point, offering an infinitely precise point of aim that doesn’t obscure the target. The reticle’s center area features fine 0.1 MIL subtensions, while the MIL Grid offers 0.5 MIL dots, extending 15 MIL down and 6 MIL to each side. This reticle also features our built-in target ranging system, which can be used to instantly estimate a target’s distance, by height or width, from 400 to 1000 yards.

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.
