Every gun smith is scared to touch my fn because no one has experience working with them. There are no videos on YouTube to help with installation and the instructions given were weak. Any suggestions.

Are you just using a mount that replaces rear sight? What model 5.7?

The mk2. I have to removed the rear sights and install the mount while slide cover is removed.
