SLx 3–18x50mm FFP Gen 2 ACSS Apollo .308/6.5 Grendel Reticle

The SLx 3–18x50mm FFP Gen II Rifle Scope is the latest evolution in Primary Arms’ SLx optics line — a series renowned for innovation, reliability, and field-tested performance. Every SLx optic is rigorously evaluated to ensure consistent results across the toughest shooting environments.

This Gen 2 model has been rebuilt from the ground up, introducing major upgrades in optical clarity, turret feel, mechanical durability, and adjustment range. You still get the wide 35-foot field of view at 3x, ideal for close engagements, and the ability to dial up to 18x for confident shots out to 1,000 yards. The redesigned magnification ring now accepts dovetail levers, including the Primary Arms Slide Mount Flip Lever for quick transitions.

With a large 50mm objective lens and generous eyebox, the scope provides excellent light transmission and clarity. And because the ACSS Apollo reticle sits in the first focal plane, all ballistic holds and ranging marks remain consistent throughout the magnification range — making it ideal for long-range shooting, hunting, and target precision. The SLx 3–18x50 Gen II blends practical features with refined optical engineering, earning its place on any serious shooter’s rifle.

This SLx 3–18x50mm Gen II FFP scope is equipped with the ACSS Apollo .308/6.5 Grendel reticle, purpose-built for precision marksmen running .308 Winchester or 6.5 Grendel. Once zeroed at 100 yards, the reticle offers holdovers and wind holds that allow you to engage targets out to 1,000 yards, even in crosswinds up to 20mph — all without touching a turret or doing manual calculations.

The chevron tip delivers an ultra-precise point of aim, while the .2 MIL crosshair subtensions provide fine control for elevation, windage, and ranging. With integrated range estimation, intuitive holdovers, and a layout that eliminates guesswork, this reticle is a complete firing solution for long-range shooting.

Combined with the Gen II’s improved eyebox, upgraded turret design, and rugged construction, this scope gives you reliable, repeatable performance — and it’s all backed by the Primary Arms Lifetime Warranty.
