Cobratac Vario 45 degree Rapid Transition Iron Sight (RTIS)

See them here!

AR-15 / M16 type, 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. Not anymore. Imagine a set of fixed backup iron sights. Now imagine that those sights are turned about 45 degrees on the axis of the bore. That is the Cobratac Vario Rapid Transition Iron Sights (RTIS) in a nutshell. It is important to note that the Varios are turned 45 degrees on the axis of the bore, not 45 degrees to the rail. This is key. 

The CTS Vario 45 degree backupiron sights are machined from 7075 aluminum and hard anodized black for durability. They sit at the same height above the bore as standard AR-15 iron sights. The CTS Vario has full A2 style rear sight windage adjustment and BDC drum. The front sight elevation adjustment is also identical to the A2 iron sights. The section over the rail is designed to be extremely low profile and the RTISs mount to the rail via slotted screws (easily field improvised).

The CTS Vario Offset iron sights give the shooter the option to have a high powered scope and a set of iron sights simultaneously available and gives them the ability to switch between the two almost instantly without changing the ergonomics of the firearm or altering the trajectory. For those who fancy themselves precision shooters and live for the distance shots yet still want to be able to post a competitive score offset iron sights offer a cheap option that keeps them in their current division but still lets them have that leg up over the other competitors.

The Cobratac Vario 45 degree rapid transition iron sight RTISs, like any new gear, will have a bit of a learning curve. They are not difficult to use at all but a little bit of practice can really hone your technique. They do require a bit of technique to be used to their full potential. Moving them into position is as easy as rolling the carbine slightly. You do not have to break your cheek or shoulder weld. The movement happens in a flash.

CTS Vario 45 degree Rapid transition Iron Sights were initially thought of as "they are just for gamers", to thinking to they are just for use with magnified optics, to wondering why they aren’t used more widely with all types of optics including red dot sights. However, many shooters still wonder where they fit in the toolbox – not because they don’t work but because they still don’t seem like a direct replacement for traditional backup iron sights. Whether or not you need offset iron sights is up to you. Regardless of weather you own a rifle which has no magnified optics where Cobratac Vario 45 degree offset iron sights are considered optional,  or have a scoped rifle, the Cobratac Vario  really does make a lot of sense.

  • No need to break your grasp on the rifle to hit a release button or raise a sight tower
  • Same bore height and sight picture as standard AR A2 sights
  • Rear sight has flip-up long- and short-range apertures, and is adjustable for windage and elevation in ½ MOA clicks
  • No special tools needed
