Canted Back-up Sights

Post by Ryan » Tue Oct 02, 2012 4:14 am

So we all know the emergency or back-up sights are normally fixed onto your more advantageous scope: normally directly on top of it. For example you've got 6x, that's all great for reaching out there and getting eyes on and accurate rounds down range but it's useless when you get into a close quarters environment. You can't clear houses with it, and looking over it may be too inaccurate in circumstances, i.e. HR in Afghanistan or operating with strict ROE around known civilian areas, and may even cost you your life if you miss. You can use a point of reference to engage, i.e. this hold and angle has me hit rounds here, but that can be easily fumbled and a point of variance can rapidly degrade your shooting accuracy for example angled shooting.

Example: Docter sight.

"...Provide shooters with the quickest possible transition between longer- and closer-range target acquisition, greatly increasing their efficiency and effectiveness in battle and competition."

Now more and more we start to see the use of "canted" back-up iron and docter sights on a 45 degree cant to a left or right of the rifle (which can depend on which hand you shoot with and/or your dominant eye side). Surefire Rapid Transition sights are one example of this. And don't just think this is for your primary rifle on an assaulter, I've seen them used on sniper rifles, which isn't too bad because a direct top back-up may get in the way of adjusting elevation, yet again a 45 degree will get in the way of either windage or focus and the likelihood of use is probably very slight. I could imagine it used more and more with NVG/Thermal kit for CQ work.

"For AR-15 / M16 type rifles, optical sights provide superior performance at longer ranges, but iron sights can be more effective for close-range engagements. However, attaching an optical sight either prevents the use of iron sights or results in a setup that produces a front sight "shadow" on the optical image, and/or results in problematic transitions from optical to backup iron sights."

"This unique offset position makes transitioning from optical to iron sights simply a matter of quickly canting the weapon with your wrists and locking on to the target. There's no removing a hand from the weapon or making a manual adjustment, and no cluttered field of vision or iron sights blocking the optical sight. Just smooth, quick transitions that could mean the difference between winning or losing a competition, or more importantly—a gunfight."

"This sight is designed for 2 purposes according to Barry Dueck:

1) As a close range sight for 3-Gun shooters to more quickly engage targets when using a magnified optic to be a faster alternative than adjusting the scope and when at close range a magnified optic reduces FOV to an impractical range.

2) As a fast transition for tactical units if the primary optic goes down. Dueck uses the example of a hostage situation when the primary battery fails.

The reason that this is not a ‘flip up’ sight is that this sight is a transitional back up. If it was a flip up then the speed advantage of transitioning would be nullified."

Also there are canted micro optic sights that serve the same sort of purpose.
