Most Helpful Positive Review YHM-227A .5" tall 5.25" scope riser
This scope riser is solid. It is a slide on style with thru bolts for clamping. It has a good range of positioning on an AR-15/10. YHM does a good job of anodizing their products. The rail does not interfere with iron sights. The rail is not QD, so QD rings/ mount could be used the get optic removed...

Most Helpful Negative Review A TIGHT fit
It is a TIGHT fit on a mil-spec picatinny AR flat-top. I literally had to beat it on with a screwdriver handle to get it into place. On the plus side, fitting that tight pretty much ensures it's not going to move.

Solid riser

by Bon, Verified Owner from PA, United States Written on January 15, 2026
It was a tight fit getting on but seems to hold well. I bought this as a cheaper solution to rise a red dot and magnifer versus the Unity risers. Solid option.

This is second scope riser ive owned. I can say it is one of the best Ive used thus far. I k ow to each is their own, but this product is absolutely great for your AR needs. And also, thanks OP for tremendous pricing, and outstanding customer service.

Great riser

by Jacob, from UT, United States Written on March 21, 2025
This mount is rock solid. If you want to bring an absolute height optic up to 1.93" height, this is the best option. It has old-school cool aesthetics as well. FYI, I emailed YHM and they said that the screws should be torqued to 25 inch pounds.
Would recommend: Yes

picatinny raised mount

by lee, Verified Owner from PA, United States Written on February 11, 2025
Lifts my scope just enough and looks pleasing. Looks low profile and doesnt add much weight.

Not what I expected

by Rogue Penguin, Verified Owner from CA, United States Written on June 20, 2024
This riser slides onto the upper receiver rail. The charging handle had to be removed before it will attach to the receiver. Both tension screws must also be removed. I have other YHM risers that have actual clamps that can be off set to place the riser for easy on/off application. I can still use it, but had I known what I know now, another item would be in my possession instead of this one.
Pros:
  • None
Cons:
  • Cannot be remove quickly if that need arises.
Would recommend: No

YHM Fan but this isn’t practical

by blake, from TX, United States Written on April 23, 2024
Solid rail, long term I don’t know if it will keep tension. Most if not all have a separate rail connector so you can get proper torque. This is just a snug fit with screws.
Would recommend: No

perfect riser

by RyHy, Verified Owner from MI, United States Written on April 13, 2024
I got this to raise my optic set up and bring my Vortex VMX-3T a little further back for better eye relief (cantilever section rearward). This fits the VMX-3T and 512c perfectly! Dont let reddit fool you, you dont need to spend $300+ for a riser. This works perfectly.
Pros:
  • Price
  • easy to install
Cons:
  • None
Best Used for:
  • red dot and magnifier
Would recommend: Yes

Works great

by Paul Rueda, from CA, United States Written on March 4, 2024
Fit Holosun 512c and HM3x magnifier perfectly. Mounts to picatinny rail and has a secure feel with no wobble or wiggle room.

Works well for the price

by Chang, from NC, United States Written on December 26, 2023
Not perfect but pretty close to it. I would recommend it. There is a gap between the riser and the receiver.
