Since it's apparent that the 556 SCM comes equipped with either the flip-up, or the hooded sight (Thanks, SIG, for more confusion!), I pose this question: Are both sight types adjustable? The feeble excuse of an owner’s manual (a whole other topic in itself!) that came with the rifle shows ONLY the flip-up sight in their photo examples concerning sight adjustment. All I can say is, “Thank God I found you folks!â€
