Product Description

Primary Arms MD-RB-AD Advanced Micro Dot Sight FDE 2 MOA Dot Rotary Knobs Removable Picatinny Mount

Product Overview - MD-RB-AD-FDE

The SLx optics are the heart of our lineup. The trusted optics that have built our reputation through the years. Although many SLx optics will be familiar to Primary Arms fans, we are always pushing forward with new generations and adding even more options in response to the demands of our loyal customers.

The Microdot, Removable Base, Advanced sight (MD-RB-AD) takes everything we learned from our popular 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 multi-coated 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.

This red dot sight is designed to work with heavy recoil and is constructed of 6061 aluminum with a Ceramic flat dark earth 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.

Reticle

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.

  • 2 MOA red dot reticle with 11 brightness settings
  • First 2 brightness settings are night vision compatible
  • Estimated 50,000 hour battery life on a medium brightness setting

What a good dot.
I mounted this on my dash to help my wife drive straight. The dot has many different settings but so far we haven't got it perfect for right hand turns. I think we have it too bright and are still trying. I love this and think it will save us money on our car insurance.

Being a clumsy man, I've dropped my rifle several times with the sight attached onto rocks and concrete, usually landing top-side down. The finish on the optic is scratched and dinged, but it still holds zero. The glass is clear, the dot is round, and there is only a minimal amount of parallax, and that's only at close ranges. What more can you ask from a budget red dot?

Pro: Glass clarity, Battery life, 2 NOD use settings, 2 MOA red dot, versatile mounting options, and on and on. Your getting a 4-5 hundred dollar sight for less than half that. I'll be getting two more of these in the next 6 months.

Con: The optical lens is only 20mm, which is ok, especially on my system and considering the quality your getting at this price point. Very, very pleased with this purchase. Once again Primary Arms delivers.

I mounted this on my AR and went to the range. Every so often the red dot turns off after one of my shots and I have to hit it to get the light back on. Very disappointed in this product.
