Replacing the front sight was easy. Rare sight has many components which a person needs to be careful not to lose items such as wind age pin and flat spring which is located under the rear sight. I lost both and had to order. To me the rear sight has been little over engineered for what it was intended for. :)
Pros: Excellent sighting tool
Cons: None at this time
