Primary Arms Optics SLx GEN III Prism Scopes

Primary Arms’ Gen 3 SLx prism scope line has a new mount and an updated reticle.

But before we go there, let’s talk about the ACSS reticle. In case you didn’t already know, the ACSS reticle designed by Dimitri Mikroulis is held in high esteem.

Here’s a video in which Dimitri explains how to use the reticle. If you haven’t seen it before, well…..we think you’ll be mighty impressed!

…the ACSS reticle seamlessly integrates bullet drop compensation, wind holds, moving target leads, and range estimation “…into an easy to use, instinctive sighting system that is very fast from 0-300 yards and very accurate from 300-800 yards.”

… They are prized because they are engineered to account for wind speed and distance, providing shooters with moving-target leads, range estimation, and bullet drop compensation.

Primary Arms, It’s Primary Optics, Primarily

And now the company is offering scopes with upgraded ACSS reticles!

Upgrades to Previous SLx 3x and 5x Prism Optics

The SLx Gen III 3x and 5x Prisms host a number of significant upgrades over the previous generation, touting even greater value at their budget-friendly pricing. These upgrades include an all-new factory mount design and a number of ACSS reticle updates.

The SLx 3x32mm Gen III Prism Scope is a general-purpose, mid-range prism optic with exceptional durability and value. Priced at $289.99, this scope is suitable for most budgets, while its impressive optical clarity has made it one of the best-selling prism optics in America. With a forgiving eyebox, brightly illuminated reticle, and proven durability, the SLx 3x Prism is highly regarded by both enthusiasts and professionals.

The third-generation update brings a fully-reengineered factory mount that greatly improves the optic’s shock resistance and zero retention. In addition, this optic has two new ACSS reticle designs, including the ACSS-5.56-CQB-M2 and ACSS-CQB-300BLK/7.62X39. After extensive testing in the field, this optic has been recommended for duty use by the National Training Officers Association.

The SLx 5x36mm Gen III Prism Scope is a precision-oriented, long-range prism optic that offers exceptional accuracy at any distance. At 18.4oz, this optic weighs less than comparable mounted LPVOs, and the integrated picatinny rail section allows for a vertically offset red dot.

Includes New Reticles such as the ACSS Aurora

In addition to the mount upgrade, the SLx Gen III 5x is also Primary Arms’ first prism optic to feature the ACSS Aurora reticle, a metric-based BDC that allows for precision holds out to 800 meters.
