Ever since tactical and practical shooters began putting glass on rifles to serve as the primary sighting system, they began to search for better ways to back up the optics with iron sights.
In the tactical community, and in 3-gun events, flip-up iron sights became en vogue—out of the way when you didn’t need them, there in a flash when you did.
As Open shooters have known for some time, putting the secondary sighting system in a usable position is much more advantageous to the shooter. Today there are several different makes and models of sights hanging on seemingly every position in which one can be hung on an AR-15.
Dueck Defense RTS
Barry Dueck’s Rapid Transition Sight (RTS) has become one of the more popular secondary iron sight systems in 3-gun. Dueck, a veteran of the Marine Corps and top 3-gun competitor, used his combined experience and took the old A2-stype sight from the M16 family, developed a mount to handle it at 45 degrees—just as Open shooters do with optics—and the RTS was born.

Because he used a military aperture and front sight post, the RTS is capable of accurate fire to surprisingly extended ranges.
So, while the RTS is intended for use hosing closing-range targets, should the primary optic go down over any distance, shooters are still in the game with the RTS.
“A must-have for 3-gun shooting,” said Practical Shooting Academy’s Keith Garcia, a law enforcement officer and two-time 3-Gun Nation Shoot-Off winner. “The best back-up sight available anywhere. These sights are so sturdy I put a second set on my SWAT entry rifle.”
