Just got these in today. Gotta say I love them so far. Can't wait to take em to the range and try them out.

I looked and didn't see anything, but how tall are these. Looking for some for the pistol that will take the heat from being suppressed, that will not affect the red dot.

They work on the ACR but guys say that they are too short for the standard AR since the rails aren't tall enough. I also have high cheek bones being part cherokee that helps me as well. So, not very tall but on the HK 416 and the ACR they work just fine. If you really want them on a standard AR you may have to get some mini risers to increase the height.
