For back up irons they are decent. Just some things to note, the rear sight doesn't fold down completely with the large aperture but will fold down on the small aperture. My front sight post has the slightest cant and fiber optic not perfectly center. The wear on the rear sight locking pin was from just 1 outing.

Reviewed in Canada on April 10, 2023
The good thing about it is the price and that aluminium. The problem is you can't adjust the front sight easily as the "tool [is] not included"
So I figured out that there is a spring keeping the sight locked and that pressing it in released the hold. Unfortunately trying to rotate the sight for elevation does not work well bare hand and using pliers risk slipping into the sight like I did. Most alternative sights have a horizontal turning dial, I'm not sure why Feyachi couldn't include a tool. 2023/04/16 - Feyachi reached out and replaced it. Good as new. My advise, but a sight adjustment tool on Amazon. This sight needs a 4 pronged one.
