Primary Arms Optics is rolling out a new reticle option for long-range marksmanship, the ACSS Apollo .308/6.5 Grendel (GRN) reticle that is now available for the SLx 3-18x50 mm first-focal-plane (FFP) riflescope. The scope combines optical quality with an intuitive reticle design, allows a capable marksman to achieve hits out to 1,000 yards with ease.

“The ACSS Apollo .308/6.5 GRN reticle is a crossover DMR/precision reticle with a fast auto-ranging BDC and integrated wind holds,” says Dimitri Mikroulis, creator of the ACSS reticle system. “This reticle uses exact MIL/MIL firing solutions to match .308 Win. and 6.5 Grendel cartridges.”

The ACSS Apollo .308/6.5GRN is a brand-new reticle which features an advanced holdover system that is calibrated to match both the .308 Winchester and 6.5 Grendel cartridges. The ACSS Apollo .308/6.5GRN blends fine mil stadia and an infinitely precise center chevron with bullet drop compensator (BDC) holdovers from 300 to 1,000 yards. These holdovers include wind corrections for 5, 10, 15, and 20 mph crosswinds, allowing the user to predict impact even in an ever-changing environment. The reticle also includes a build-in ranging ladder, which can be used to estimate distance-to-target by both height and width. Combined with the scope’s excellent glass quality, users are able to leverage this reticle to its fullest potential, achieving first shot hits with improved consistency and speed.

The ACSS Apollo .308/6.5 GRN reticle is available first on the SLx 3-18x50 mm FFP riflescope, which is part of the Primary Arms SLx optics line. All SLx optics undergo rigorous field-testing during development to best serve the user in any environment. Every SLx 3-18x50 mm FFP riflescope is 100-percent hand-inspected in Houston, TX, to ensure reliable function and optical clarity.

The other features of the SLx 3-18x50 mm include daylight bright illumination, locking resettable turrets, and an extra-smooth magnification ring with removable power fin. These features, combined with an affordable price point and high quality glass, allow the SLx line to compete with scopes that have a much higher price point. 

MSRP for the SLx 3-18x50 mm FFP with ACSS Apollo .308/6.5 GRN Reticle is $479.99, and for more information on this item or other gear from  Primary Arms, please visit

Mental Focus vs. Mental Awareness

Shooting at the very edge of your skills envelope requires tremendous mental focus and well-developed shooting awareness. However, some shooters believe that shooting awareness and mental focus are one in the same. They are not. Using pistol shooting (combat or competition) as an example, what is the difference between the two and how can it help you hone your shooting skills to a razor’s edge?
