Overall, it is a set of good BUIS. My only complaint is that the rear sight won't fold while it's in small aperture. You'll have to switch to large aperture in order for the rear sight to fold completely. Other than that great quality for the price.
Pros: Easily accessible, good coating, durable
Cons: Rear sight can't be folded down while in small apecture
