Details

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.

Features:
  • 2 MOA red dot reticle with 11 brightness settings
  • Nightvision compatible
  • 50,000 hour battery life
  • Aluminum 6061 construction
  • Ceramic flat dark earth 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 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. 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.

Unsure

Just installed and already have a few dislikes.It is a nice solid piece of equipment and seems to be well made, but why the right side knob? You hold your gun with right hand. The 11 settings start with infrared and dimmest and it takes two turns of wrist to get to brightest. Knob is very stiff and I dont think it would turn with gloves on. If you order the riser mount, it is black, not flat dark earth.

A serious contender to Aimpoint, at a quarter the price

by

I have two of these, several Aimpoints, and the previous Primary Arms (PA) micro dot. While the previous PA was excellent, I always had concerns that the buttons could be a failure point. This dot uses the same dial design as Aimpoint, and should be very reliable. It also includes a lifetime no-questions warranty, which Aimpoint does not.

The one downside of this compared to the previous PA is the glass has slightly more red glare and emitter reflection, however it's still better than the Aimpoint H1, which has much worse glare and reflection.

The knob is stiff, but it needs to be so it doesn't accidentally rotate, and it loosens up with use. The Aimpoint dial is also stiff. The dial is on the right, just like an Aimpoint, so it's not blocking your eye sight.

This is, all in all, the best micro dot on the market and my go-to. The battery life is on par with Aimpoint, warranty is better, glass is clearer, and not only is it much cheaper, it's even cheaper than its predecessor.

Great red dot, worth the money.

An amazing little red dot, that is built like a tank and looks incredible. You will need a riser if you want a co-witness. Worth the money

Time will tell...

I own and run both Aimpoint Micro T1 and T2. So far I am very impressed with the Primary Arms SLX Advanced Rotary Knob red dot. The turret knobs are a bit bulky and so is the adjustment knob, but not a deal breaker, just an observation. I don't know why anyone would complain about where the adjustment knob is located because both of my Aimpoints have the knob in the exact same place. A lot of snobs will find fault with any product that does not have a name brand or following. They will talk about blue tint, slight magnification, blah blah blah. If it holds zero, does not crap out, and allows you to get shots on target; that's good enough for me. Like I said, time will tell...

Great Red Dot!

I was looking for an optic to go on my home defense shotgun. It needs excellent battery life so that you can leave it always on (check), low mount for the shotgun (check), and a great track record (check). The FDE finish is flawless and it matches my MAGPUL furniture, which is awesome. I have a Sig Romeo 5 and this is equally high quality. It has everything the Romeo 5 has except for the shake awake, which is a moot point with 50k hours of battery life. I'm glad I didn't have to pay more for a high mount that I didn't need and I can always get it in the future if I need. Highly recommended.

another Primary Arms red dot knocks it out of the park

by

I put this little FDE beauty on a 9mm PCC upper. It's perfect for hitting steel plates and PCC matches. The knob is a bit hard to turn...what's up with that??

Great red dot!

Good clear dot easy to sight in have one that I have had for years felt confident to buy another one would have given 5 stars but brightness adjustment knob is very tight when adjusting brightness.

I have several of these Primary Arms Red Dots on rimfire rifles, AR15's and Handguns. They work great...I've never had a minutes trouble.

Nice

Great red dot for the price. Was very easy to sight in and holds zero. i like the small size on the AR. Not big and bulky like others. Have 2 of them now.

Perfect match!

Love it! Flawless, BUT, it does not come with a raiser mount! Primary arms needs to just add it and incorporate it with the cost. Like sigsauer! Simple minds for simple logic!!
