Most Helpful Negative Review Overpriced, non-spec
The rear aperture was nearly out of adjustment all the way on the left hand side. I have had Yankee Hill BUIS on the same gun with no problems. The other thing is the rear aperture is not mil-spec.

best in class

by vltorfan, Verified Owner from GA, United States Written on March 6, 2024
If you’re putting BUIS on a gun, then you want them to WORK. Locks up, tactile dials, clear sight picture, and doesn’t impede charging handle use. Arguably better than the lauded KAC BUIS. I have the Magpul Pros and their regular polymer sights as well. This is honestly best in class. Buy it.
Pros:
  • Best
Cons:
  • None
Best Used for:
  • Reliability
