So far it has worked well and installed like most sights (not easy), but that was expected. The only comment I have is the 2 adjustment screws that are supposed to be locked down after you adjust the sight don't seem to work. The allen wrench that came with the rear sight doesn't seem to fit. I tried different allen wrenches, but they also don't seem to fit. I posted a comment asking for guidance, but I have received a response yet. This is the reason I only gave the product 4 stars. If the lock down screws worked it would have been a 5.
