Can any Nerf gun use a scope?

you can put a scope on most new Nerf guns, using the tactical rail (i think that's wut its called) and putting a scope (its technically not a scope because it doesnt magnify anything) on it from a longstrike or longshot. if it doesnt have one you can tape one on, or if you mean a real scope you might be able to tape it on or put on a rail from an airsoft gun or a real gun. not many Nerf guns will accualy be accurate with the scope because they are so week, unless its modded and has alot of power.
