BTW - A front sight hood isn't necessary for peep sight use.
In fact, I find a hood detrimental, since it detracts from the available illumination on the front sight's bead/face.
I have a scrounge box in my workshop, filled with sight hoods, some dating back to the first rifles I acquired with them, in the late 1950's. .
I re-install them on rifles I sell - just to satisfy those folks who can't seem to be satisfied w/o one. .
