After rigorous field testing, this optic has earned a gold-tier rating from the National Tactical Officers Association.
This Primary Arms red dot sight is part of the proven SLx optics line—respected for its innovation, reliability, and value. All SLx optics undergo extensive field testing during development to ensure consistent performance across a wide range of environments.
The SLx MD-25 Gen 2 with ACSS CQB reticle now includes AutoLive® motion-sensing technology to further extend its already impressive battery life. AutoLive® automatically powers down the optic when idle and reactivates the reticle the moment motion is detected—ensuring the optic is always ready. With the same compact footprint, lightweight 25mm profile, and a field of view that rivals many 30mm red dots, this next-generation model continues the SLx tradition of practical enhancements without added bulk.
The ACSS CQB reticle incorporates a central chevron with bullet drop compensation dots for engaging targets out to 600 yards with 5.56 NATO or 7.62 NATO. The auto-ranging and wind hold elements provide additional precision, while the outer CQB horseshoe aids rapid acquisition at close range and approximates 00 buckshot spread at 25 yards.
Features:
The Gen 2 SLx 25mm red dot sight includes the next-generation ruggedised mount, upgraded in material, design, and durability. Integrated recoil lugs and enlarged crossbolts provide improved clamping strength, ensuring the optic remains securely mounted under recoil. The included riser is suitable for AR-15 and AR-10 platforms but can be removed for use of shotguns or other firearm types.
Each optic ships with a low base, standard riser, and two height spacers, offering mounting heights of 0.96”, 1.41”, 1.54”, and 1.64”. These options allow users to configure their setup for perfect alignment with their firearm and shooting preferences.
