Primary Arms Optics has expanded its SLx® lineup with the release of the new SLx Compact 4-16×44mm First Focal Plane rifle scope, a mid-power optic designed to deliver precision capability in a notably compact and lightweight package. Measuring just 10.1 inches in length and weighing 20.5 ounces, the new SLx 4-16×44 is aimed at shooters who want extended-range performance without adding unnecessary bulk to their rifle.

Positioned for use on lightweight hunting rifles, compact DMR-style builds, and practical precision setups, the 4-16× magnification range provides enough top-end power for distance work while remaining usable at lower magnifications for faster engagements. The first focal plane design ensures that reticle subtensions remain accurate throughout the entire magnification range, supporting consistent ranging and holdovers. An adjustable parallax system ranging from 10 yards to infinity further broadens the scope’s versatility, allowing it to be used across rimfire, intermediate, and full-power rifle platforms.

Primary Arms is offering the SLx Compact 4-16×44mm with three ACSS® reticle options. The ACSS DEKA G2 provides a clean MIL-based layout with a fine 0.1 MIL center dot and integrated ranging features. The ACSS Athena BPR MIL reticle offers a more traditional grid-style layout with a precise chevron aiming point and extended hold capability. Shooters preferring a BDC-based system can opt for the ACSS HUD DMR .308 reticle, which incorporates ranging, wind holds, moving target leads, and ballistic compensation out to extended distances.

"Our goal was to build a truly compact, lightweight mid-power scope without sacrificing optical performance," says Stephen Morgan, Director of Product Marketing at Primary Arms Optics. "The SLx 4-16x44 delivers on that promise, and at a price accessible to most enthusiasts. So, whether you're hunting deep country or tightening groups at long range, this optic will give you confidence in every shot."

As with other SLx optics, the new scope is shockproof, waterproof, and fog-resistant, and it is backed by Primary Arms Optics’ Lifetime Warranty. The SLx Compact 4-16×44mm FFP Rifle Scopes are available now with an MSRP of $349.99 through Primary Arms directly or authorized dealers.
