Most Helpful Positive Review Rock Solid
As my title suggests, this is a very secure mount, for my PA, 3X, PA magnifier. It’s extremely rugged, with steel construction. I bought an additional 1.93 spacer, to line up with my gen II PA Cyclops, 1x prism micro-dot, which also has a 1.93 mount. The magnifier mount, does come with an absolute co-witness spacer and a 1/3 co-witness spacer. But, I prefer the faster sight acquisition of a taller optics mount. Especially since the Primary Arms micro-optics, have etched glass, and therefore do not need backup iron sights. I do see the use of a taller, Unity optics mount, being problematic, as...

Pay the $20 Extra

by Lucky, Verified Owner from TN, United States Written on May 20, 2025
I went to buy the push button mount, but due to it being $20 cheaper, it was on backorder. After receiving assistance from an OP rep., I was able to pay the difference and get this one shipped out for less than a $20 difference. Im glad I was impatient and went with this one. Taking it in and out of sight position is so satisfying. It is very audible and should never have an issue with going in or out of position unless I hit it hard on something and if i hit it hard enough to move it, at that point im looking over my rig to verify all is well. Spend the little extra to get the better quality. Do yourself that favor.

Works Great

by Keypunch, Verified Owner from CA, United States Written on May 7, 2025
Really strong lockup so it won't be defeated unless you press the button. Ideal for moving quickly during training and not having to worry about your magnifier getting bumped out of the way on accident.

Great mount for magnifier!

by Frosty77, Verified Owner from TX, United States Written on March 1, 2025
This magnifier works great and looks awesome. Easy to manipulate and very good quality. It's a little stiff at first but will get better after use.

910094 2-bolt mount, does it's job

by abe, Verified Owner from MA, United States Written on December 19, 2023
This is a review for the two bolt version, not the thumbscrew+button version.

Upgraded from a Vortex push-button flip mount, and I do prefer this one. In spite of there being no active lock it still holds things in place with negligible free play or movement, and the two bolts hold things nice and flush to the top rail. Makes running the charging handle on my BRN-180 upper a bit easier (I have it switched to the AR180 Parts knurled straight handle but I feel like the stock one may play nice with it). Absolutely nothing remarkable or notable otherwise, which is what you want in mounting hardware.
