I was trying to avoid that as i dont really have trust in accuracy in a front sight not mounted on the barrel. Seeing as how pressure on handgaurds effects accuracy at range i can only think that pressure on a FF handguard would have more of an effect on POA/POI. Beginning to think i i just dreamed up this type of a sight.

Possibly best case scenario is the YHM sight pictured. Any one know if a FF hand guard will slide over that sight when its collapsed?
