Leapers UTG is just one of those cheap brands that you buy and don't expect much from but they always seem to deliver. This RMR mount is just one of many products that has gone above and beyond my expectations. I bought a cheap mini red dot with the RMR footprint to see how well I would like it on my AR pistol and needed a mount. Not wanting to spend a bunch of money I picked this up because of my experience with Leapers from past products. This attached very securely to the rail and the sight. I will definitely be upgrading the sight but I will continue to use this mount as long as it holds u...

Give it a chance

by Jonny, Verified Owner from IL, United States Written on December 1, 2024
I normally keep scrolling when I see this brand, but this thing excels at the simple job it needs to do, looks better than expected, and costs about 1/5 the price of other RMR footprint mounts. It even included some pretty solid screws to mount the optic.

In service for 8, maybe 9 years…

by Wendell Sawyer, from OH, United States Written on August 8, 2023
The least expensive, longest running mount you will ever buy. Sure it isn’t quick disconnect and is basic as it gets, but it does what you expect, better than you expect. Get it, Set it and forget it. It’s solid.
Pros:
  • solid
  • Ligh weight
  • Inexpencive
Cons:
  • None
Best Used for:
  • rifes
  • PCC
Would recommend: Yes

Pretty Darned Good

by OhYeah, from TN, United States Written on December 4, 2022
I wanted to put a Holosun 507C on my AR and was shocked at how much risers are... that is, except for this one from UTG. It fit perfectly and is reasonably lightweight.

I can't see any reason to spend more.
Pros:
  • Excellent value
  • fit perfectly
Cons:
  • None
Best Used for:
  • Anyone needing an RMR AR Lower 1/3 riser.
Would recommend: Yes

UTG gets it right more often than not

by Dan, from FL, United States Written on September 8, 2022
This is one of those times. This mount has a Solid lockup and is lightweight alternative to many other more expensive alternatives. Not sure what else there is to say about this.

I used this with a holosun 507c

Fits well with RMR

by pabluras, Verified Owner from WI, United States Written on June 7, 2020
1/3 co-witness supports a Trijicon rmr(type 2) to align with the magpul mbus flip up sights. When the pop-up sights are down the channel through the mount is wide enough to allow a sight picture which is nice compared to some that are solid/have no channel. The hold is solid and fits perfectly for the RMR.
Would recommend: Yes
