No you are on the right track just think it through a little, and decide what is best for You and Your apllications, I personally use both clamps and pins. Clamps on target/match rifles and pins on "work" rifles even tho I have never had a clamp work its way of. And for sights I prefer to have them on the gas block so My sight radius is as long as posable It makes the front post easier for me to focus on, flip up, Clamp on, or standard "triangle" depends on my personal aplications. I tend to go with the standard as there is no chance of the front sight moving when I flip it up and down or get it hung on a tree branch or rock and having it fold down on me.

Have fun and welcome.
