Questions & Answers
will this work with Pa acss cyclops? Manufacturer Answer

Greetings and thank you for your interest in Primary Arms products. Yes, this item will work with the Cyclops optic.

by Primary Arms Optics, Manufacturer, September 10, 2020
Will this work with the Slx micro prizm (spacers)? Expert Answer

No. This Primary Arms Lower 1/3 Cowitness Micro Dot Riser is designed to fit optics that use the Aimpoint T1/T2 optic footprint. The Primary Arms MicroPrism does not use the T1/T2 footprint.

Very nicely made product by Tonester, May 19, 2018
A friend recommended this riser mount to me and I’m glad I chose this. It’s a very nicely constructed product. It fits my primary arms red dot perfectly. This will work nicely with the iron sights on my 15-22 rifle.

Great for a 1/3 co-witnes and light weight by TripleM, Verified Owner, February 3, 2018
I bought for a Sig Romeo 5, but too hiigh for a 1/3 co-witness with burris or vortex 1/3 co-witness magnifier mounts. Also it would have been great if mounting screws would had been included for the price. Great for a Holosun, and my other T1 clone ...

Awesome mount for a little price by Bigblok396, January 6, 2018
Came just as described. Mount well to holosun red dots and primary red dots. The lite frame adds no weights and sits perfect for that 1/3 co witness. Easy to mount both in the rail and to the red dot itself. Would recommend this if you’re on a budget...

Good for S&W M&P 15-22 by Nick Nomen, August 30, 2016
I used this to mount a Primary Arms Micro Dot on a S&W M&P 15-22. The setup does a good job of simulating an Aimpoint Micro with a lower 1/3 cowitness. It's a little primitive but seems to be holding up fine.

PA 1/3 cowitness by AW, March 23, 2016
When mounting the PA md ads sight with this 1/3 cowitness riser mount it was just as it says. It's worth the minimal cost and in my opinion is better then having your MBUS sights in the middle of your optic. I would Recommended...

Simple piece. Mounts well. by Chuck Daddy, June 28, 2019
Attached this to a romeo5 and mounted on a Mossberg MMR. Creates a perfect height for lower 1/3 cowitness. So far I’ve put over 300 rounds down range and it’s holding steady. Only major concern is the screw holding the mount to the gun looks/feels br...

Product Info for Primary Arms Classic Lower 1/3 Cowitness Micro Dot Riser Mount

The Primary Arms Lower 1/3 Cowitness Micro Dot Riser allows for a lower 1/3rd cowitness on AR15 and similar platforms when combined with any Primary Arms Micro Dot, as well as many other standard Micro dot designs. When looking down the iron sights, the red dot will be placed in the bottom part of the Micro dot's scope tube. The lower 1/3rd cowitness setup allows a less obstructed view of the entire scope tube when using the red dot instead of the iron sights. The light weight design, constructed of anodized aluminum, is easy to install. The riser Features a lifetime warranty.image
