Urban Survival Firearms - Back Up Iron Sights received a new comment on the post, Urban Survival Gear - My Basic Kit: Load Bearing ...: “Anonymous said,…..Remember to know how to use ALL that fancy scopes and what not on your AR-15/ M-4 rifles. Good old fashion iron sights are the way to go! If you can’t see at night, hide well!”

UrbanMan Replies: I absolutely am a fan of iron sights,….given a choice between iron sights or a scope, I would choose iron sights. I carried an M-16 then an M-4 for over two decades using only iron sights, when I wasn’t assigned a scoped bolt gun. I started using various scopes, first the old Bushnell-EO Tech precursor when I was teaching shooters to use the same. I have used many scopes over the years,…primarily the Bushnell, EO Tech, Aimpoint Comp ML-2, Trijicon TA-42 and TA-11’s and Leupold CQT. If I had to pick a scope from the aforementioned list, it would probably be the Trijicon TA-42, but they are pricey so I don’t have one on any of my M’4’s. My work gun has an EO Tech.

If you mount a scope on your M-4 you should also have BUIS (Back Up Iron Sights). Lots of good types out there. I happen to use the old A2 version BUIS from GG&G, although there are many makes and models of M-4 rear sights out there, presuming you have an M-16/M-4 with the OEM front sight.

Troy Industries, MA Tech and A.R.M.S. all make BUIS that I have used and are familiar with. I really light the MA Tech BUIS except for the fact that the spring loaded aperture often loses or breaks the spring under repeated use. In my opinion, the GG&G is a robust BUIS and as good as any, better than most.

  1. Exactly the information I was looking for. I bought what they call an Optics Ready Carbine from a friend of mine, but there are no sights. I want to put a scope on it,..was thinking about a 2x9 rifle scope, but will wait until I get iron sights as I agree they are most important. Any chance of you doing an article on lights for handguns and rifles? Do I need one of those lights that attaches to my pistol? How about my carbine ?

  2. Excellent information to sharing increase the scope.

  3. How to Make Pemmican The Ultimate Survival Food

    Invented by the natives of North America.

    Pemmican was used by Indian scouts as well as early western explorers.
    These people spent a great deal of time on the go and depended on having portable, high-energy, highly nutritious, and filling foods that would last for long periods of time without refrigeration.
