### ⭐⭐⭐⭐⭐ Fits perfect on my ATI

Fits like it should

### ⭐⭐⭐⭐ Works
*by Z***Y on February 2, 2026*

Works great. The hardware, which is 2 small threaded allen pins, feels like it could slip. I used some thread locker and it's fine. Other than that it hold well and doesn't wiggle. I actually have one stacked on the other so it brings the mount from where it connects to the 12 oclock rail on my rifle to the 9 o'clock where I have a IR illuminator.
