The Primary Arms SLx 3-18x50mm FFP riflescope features the new ACSS Apollo Reticle.

The SLx line of optics from Primary Arms has built a reputation for innovation, reliability and value. With constant upgrades and additions, like the ACSS Apollo .308/6.5GRN reticle, Primary Arms steps up their long-range game. As a result, the newly updated SLx 3-18x50mm riflescope helps capable marksmen achieve hits out to 1,000 yards, without issue.

The addition of the ACSS Apollo .308/6.5GRN reticle will be available on the SLx 3-18x50mm FFP riflescope first. With high quality glass, locking zero resettable turrets, extra smooth magnification ring with removable power fin and 0.1 MIL click turrets, the SLx is competitive with higher priced scopes. Likewise, a smooth parallax adjustment and fast focus eye piece provide a top-tier crisp image of both target and reticle.

The ACSS Apollo reticle features an advanced holdover system that is calibrated to match .308 Winchester and 6.5 Grendel cartridges. Additionally, the Apollo displays BDC holdovers from 300 to 1,000 yards, via a blend of fine MIL stadia, an infinitely precise center chevron and .2 MIL crosshair subtensions. Also, with wind corrections for 5, 10, 15 and 20mph crosswinds, the user can predict impact during changing conditions.

The ACSS Apollo includes a built-in ranging ladder for estimating distance-to-target by both height and width. The illuminated reticle features daylight bright illumination, coupled with an illumination turret with six brightness adjustments. Furthermore, with the placement of the reticle on the FFP (first focal plane), it will remain ‘true’ at every magnification.

“The ACSS Apollo .308/6.5GRN 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 Winchester and 6.5 Grendel cartridges.”
