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 Microdot, Removable Base, Advanced sight (MD-RB-AD) takes everything learned from the best selling MD-ADS microdot and refines it a step further. The Primary Arms Advanced Micro Red Dot Sight features an estimated 50,000 hours of battery life from the included CR2032 battery, powering an ultra-sharp 2 MOA dot. Fully multicoated lenses and an ultra-low profile emitter ensure a clean sight picture with minimal lens tint. Eleven brightness settings are controlled by the rotary knob on the right side. The first two settings are compatible with night vision units and cannot be seen by the naked eye. The brightest settings are daylight bright. The illumination knob physically stops at “0” with the red dot turned off.

  • 2 MOA red dot reticle with 11 brightness settings
  • Nightvision compatible
  • 50,000 hour battery life
  • Aluminum 6061 construction
  • Hardcoat anodized matte black finish
  • Waterproof
  • Includes removable picatinny mount
  • Includes CR2032 battery
  • Lifetime warranty

Covered by the Primary Arms lifetime warranty, this red dot sight is designed for use on heavy recoiling firearms such as shotguns and is constructed of 6061 aluminum with a Type II anodized matte black finish. Waterproofing is improved over previous models—for example, the turret caps are now aluminum instead of plastic and tighten down around the O-rings until metal-to-metal contact with the scope body. When removed, the turret caps can be used to adjust windage and elevation. It comes with a removable 1913 MIL STD Picatinny base. With the base removed, the scope body is compatible with industry standard micro mount systems, enabling The Advanced Red Dot to be mounted correctly on a wide variety of firearms.

For the money, great red dot.
<br>Purchase for my nephew, .22 break down semi-auto.
<br>His future Xmas gift.

An obvious upgrade


I wanted to upgrade from my Bushnell TRS-25 specifically for battery-life purposes and didn't feel dropping 1k on an Aimpoint. I picked this up along with the discounted American Defense Quick Detach T1 Micro Mount - Absolute.
<br>Zeroed it at the range and took the optic off the rail to see if it would hold zero and sure enough , it was spot on when I reattached it. Did this about 10 times and every time it was on the bulls eye. Never lost zero.
