to a scope, "folding' sights, be my guest.I want a PROTECTED set of luminous iron sights, and a QD,return to zero scope base. You can HAVE your battery dependent,fragile electronic sights and scopes for shtf. A scope, as an auxiliary, specialized sighting system, ok, but as the MAIN sight, never. A fragile, exposed iron rear sight, on a flip up mechanism,not me, thanks just the same. For a specific "mission", TODAY, sure,maybe the electronic sight would get the nod, as long as the removable carrying handle, and its sight, are ALONG as back up. I aint bothering with such for shtf, tho.
