Collimator Primary Arms SLx MD-25 25mm Micro Dot Gen II AutoLive ACSS CQB Red Dot

Primary Arms SLx MD-25 ACSS-CQB is a lightweight and durable closed-design red dot sight. Thanks to the AutoLive motion sensor, it is practical and energy-efficient. Tested under rigorous conditions, it is suitable for high-recoil firearms and designed to perform reliably in harsh environments, including rain and dusty conditions (IP67 standard). The sight body is made of aluminum and filled with nitrogen to prevent lens fogging. For fast and precise target acquisition in any lighting, it uses a 2 MOA dot with 12 brightness levels. Anti-reflective coatings provide good light transmission and a clear, distortion-free image.

Battery and AutoLive

The Primary SLx MD-25 ACSS-CQB stands out with an impressive battery life of up to 50,000 hours, over 5 years of continuous operation. This energy efficiency is ensured by AutoLive, which turns off the sight when the firearm is stationary and activates it when moved. This convenient and practical system significantly extends battery life and reduces operating costs. The kit includes risers and spacers, allowing easy installation on AR, AK rifles, shotguns, and more.

ACSS-CQB Reticle

The sight features an ACSS-CQB reticle designed for close-quarters shooting. It consists of a chevron and three dots surrounded by a prominent red horseshoe. Allows for bullet drop compensation for 7.62 NATO or 5.56 NATO rounds up to 550 meters.

Primary Arms SLx MD-25 ACSS-CQB — Sight Construction

The body is made of anodized aluminum. The matte finish protects against oxidation and hardens the surface, making it scratch-resistant. The sight is lightweight and durable, measuring 76.2 mm in length and weighing 184 g. It is ideal for shooters aiming to reduce the weight of their firearm and optic setup.
The brightness adjustment knob is located on the right side of the body and is easy to operate. The first two settings are for night vision use, and the last one is for bright sunlight.
The 25 mm lenses are coated with anti-reflective layers for a clear image and allow for both-eyes-open shooting without parallax error.
