Most Helpful Positive Review A little steep in price but worth it.
After purchasing a new Eotech G23 that was missing a mount at a ridiculously low price I searched for the mount and came across opticsplanet.com, it seemed a lil pricey for just the mount alone but honestly since both the G23 and mount were well under $300 total it was worth the purchase. Absolutely...

Most Helpful Negative Review unimpressed for this price
The one I received over rotates and does not line up perfectly and squarely with the optic in front of it. It’s still usable, but for the price I would expect better.

Mount does not line up correctly.

by Stropp, from TX, United States Written on July 30, 2025
Had high hopes for this but it is canted about 2 degrees and is not centered on the rail. So much for qc. Everything else I have by other manufacturers lined up perfectly. Would not buy this and in light of them selling this, crossing them off the list for anything.
Pros:
  • Supposed quality history
Cons:
  • Questionable machining
Would recommend: No

Optic not level

by Arby, Verified Owner from OK, United States Written on December 25, 2024
This mount is well built, but it over rotates and leaves the optic tilted and not centered on the red dot. I don’t think it affects shooting performance, but for a mount that costs $200, I would expect the optic to be level and perfectly centered. Disappointed with the purchace.

Works with Primary Arms GLx 6X Magnifier

by average joe shooting, Verified Owner from CA, United States Written on April 9, 2024
Got this QD flip to side for my Primary Arms GLx 6X Magnifier. Wasn’t much info if it mounts the same or not but looking at the stock photos gave me a good idea. And once in hand I can definitely confirm it fits. The spacers that come with the mount vs what the PA magnifier came with are different heights. So if you get this you will have to stock the spacers without the screws to see which ones will work for you. I use 1 magnifier across 4 rifles. So needed something that quickly can move rifle to rifle. There was nothing wrong with what PA came with. Just that mounts with a 2 bolt system and I don’t always carry the needed star wrench on me.

mounting issues

by Joe, Verified Owner from KS, United States Written on August 21, 2023
It works now but it was a pain to mount. To get it correctly on the rail you have to take it all apart to get it to mount correctly. Can't loosen the screw out out all the way either. It has the making for a good mount but needs to be engineered better. When I took the mount apart there were 2 springs that went flying took a day and a half to find them. There wasn't anything in the instructions that say that all had to be done.
Pros:
  • it works
Cons:
  • mounting issues
Would recommend: Yes
