Since SHOT Show the KAC SR-15 E3 Carbine/IWS rifles have been slowly trickling out of the factory. I believe that they are now in full production.

The Stoner Rifle 15 series are semi-automatic rifles featuring a 16″ chrome chamber barrel, a URX free floating barrel system, an ambidextrous control system, a two-stage trigger, an improved multi-lug E3 bolt and integral front sight and sling mounts. This is already a comprehensive package on its own and does not require excessive modular accessories for performance enhancement. The KAC SR-15 is the first rifle model with an Integral Weapons System (IWS) that combines both built-in and modular features.

One of the upcoming guest blog posts is a review of the SR-15 so watch out for it.
