Easy Install, Knights Quality by Owen, Verified Owner, April 22, 2024
Perfect low profile sight for my DDM4A1. Installs in a second and feels extremely sturdy and well built. Flips up easy and will not budge unless you want it to.

If you choose to spend this kind of money on you build than it's 100% worth it! If you are doing a budget build than this isn't the sight/brand for you.

Completed my correct MK18 Mod 1 clone by Michael Root II, Verified Owner, December 24, 2023
A rock solid sight that does what it's supposed to, but it isn't worth the greatly inflated price just because of the name. It isn't any better than the competition costing nearly half the price.

It's not cheap. But well worth it. by TYLER WILLIAMS, Verified Owner, February 18, 2020
This front sight is perfect for your block II Builds/ MK18s. Stows easily when running optics, and flips up when your not. Have not had the chance to zero with this front sight but I'll update once I do.

Solid and robust by Erich, Verified Owner, January 8, 2026
This sight is great for clone builds due to the price as a back up iron sight. It's very well made and sturdy.
