Product Description

Primary Arms SLx Advanced Push Button Micro Red Dot Sight - Gen II Infographic

This Primary Arms red dot sight is part of the SLx optics line. SLx optics built their reputation for innovation, reliability, and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.

The Primary Arms SLx MD-20 Micro Red Dot Sight is the perfect blend of the advanced technology and features of the SLx MD-25 red dot and the form factor of the wildly popular MD-ADS! The newly designed body is aggressively styled and features low-profile, shielded adjustment turrets to minimize the risk of snagging in rifle cases or the bush. The new high-power emitter provides true Daylight Bright settings on the highest setting. To further boost that battery life, the SLx MD-20 is equipped with AUTOLIVE motion activation. This feature turns off the optic when not in use and immediately comes back to life when it is moved, extending both the battery life and the life of the emitter. Compact, durable, and powerful, the SLx MD-20 is the perfect optic for your next build!

Primary Arms SLx Advanced Push Button Micro Red Dot Sight - Gen II

2 MOA Dot

MD-RB-AD features a 2 MOA dot, meaning the dot itself appears to cover roughly 2 inches of target at 100 yards. The 2 MOA dot offers an excellent compromise of both speed and accuracy.

Magnifiers placed behind the microdot unit will result in a sight picture comparable to a traditional magnified scope. When looking through the magnifier, the dot will appear to “grow” in size. The dot always stays the same size relative to the target; magnification makes it appear larger.

  • AUTOLIVE Motion activation
  • Ultra-sharp 2 MOA dot
  • Fully multi-coated anti-reflective lenses
  • High-powered emitter for Daylight Bright illumination
  • Fits any industry standard micro mount and gives stated cowitness
  • Ambidextrous top-mounted push button controls
  • Waterproof to 6ft. with turret caps on, water-resistant with turret caps off, and fog resistant
  • Estimated 50,000 hour battery life on a medium brightness setting

Customers like the compatibility of the aiming scope sight. They mention that it is durable, waterproof, has a wildly long battery life, and is NV compatible. The red dot is well built and looks great, but the dot itself is not crisp looking. Some appreciate the quality, reliability, and price of the product. The one mounted on their AK is rock solid.
