Primary Arms SLx 1-6x24 SFP Rifle Scope Gen IV - Illuminated ACSS Nova 5.56/.308 Fiber Wire Reticle

Next-Gen Optics with Enhanced Speed, Clarity, and Precision

The Primary Arms SLx 1-6x24 SFP Rifle Scope Gen IV takes everything you loved about the SLx series and elevates it with a redesigned optical system, faster adjustments, and advanced reticle technology. This refined LPVO is purpose-built for dynamic shooting scenarios, offering crystal-clear glass, quick target acquisition, and rugged reliability—all in a compact and lightweight package.

Engineered for Fast, Accurate Engagements

At the heart of this scope lies the illuminated ACSS NOVA 5.56/.308 reticle, powered by Red Dot Bright fiber wire technology for superior visibility—even in bright daylight. Designed for both 5.56 and .308 platforms, this advanced reticle provides bullet drop compensation, target ranging, and moving target leads, giving shooters a tactical edge at every magnification level. The second focal plane (SFP) construction ensures the reticle remains the same size throughout the zoom range, while the built-in dovetail throw lever makes magnification changes fast and fluid. Whether you're at 1x for close-quarters work or 6x for mid-range shots, the Gen IV scope keeps you on target with precision.

Compact and Reliable for the Field or the Range

With its 10.4-inch length and 17.9 oz weight, this scope fits seamlessly on AR platforms using standard 30mm mounts. It boasts 120 MOA of windage and elevation adjustment, a wide field of view up to 120 feet at 100 yards, and a generous 4-inch eye relief for quick target transitions and comfortable shooting. Whether you're upgrading your carbine, building a DMR, or seeking a dependable LPVO for duty or competition use, the SLx 1-6x24 Gen IV delivers elite-level performance at an unbeatable value—and it’s backed by the Primary Arms Lifetime Warranty.
