ACSS MIL-GRID reticle

The scope is equipped with the ACSS Athena BPR MIL GRID reticle, designed for maximum precision at long range. Instead of a traditional crosshair, it uses an inverted V-shaped chevron that provides an extremely precise aiming point without obscuring the target.

The central portion of the reticle features fine graduations every 0.1 MIL for accurate adjustments. The MIL GRID structure includes reference points every 0.5 MIL, extending 15 MIL downward and 6 MIL to each side. An integrated ranging system allows quick distance estimation from 400 to 1,000 yards, enabling efficient corrections without additional tools.

Durable and reliable construction

The SLX Compact riflescope is built to strict Primary Arms standards using 6061-T6 aircraft-grade aluminum. It is resistant to recoil, impact, water, and internal vapor, and its precision internal components are extensively tested with live-fire use. Supported by a lifetime manufacturer’s warranty, the scope delivers long-term reliability and advanced performance for hunting, sport shooting, and recreational use.
