ACSS Deka G2 reticle

The ACSS Deka G2 reticle is designed for shooters who demand precision without compromise. At its center is an exceptionally fine 0.1 MIL aiming point, allowing a clear and unobstructed view of the target even at maximum magnification.

The reticle features a clean, easy-to-read scale with dense markings at 0.1 and 0.2 MIL intervals, combined with an integrated ranging system. This allows rapid distance estimation from 300 to 1,000 meters and immediate application of corrections without taking your eyes off the target. The design simplifies complex ballistic calculations into a fast and intuitive shooting process.

Durability and reliability

The SLX Compact riflescope is built to strict Primary Arms standards, using 6061-T6 aircraft-grade aluminum for the housing. It is resistant to recoil, impact, water, and internal vapor, and its precision internal components are thoroughly 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.
