Knight’s Armament SR-15 E3 Carbine/IWS

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.

    What I really like about Knight’s AR lowers is the integrated quick detectable swivel mount. You can see it on the second picture right behind the safety/fire switch (already have a quick detectable swivel attached to it). You don’t have to replace the back plate for single point sling.

    This is a quick detectable swivel for those that is new. The mount is a hole to put the swivel in.

    I’ll bet you this, for the same price you can buy two Colts AR. KAC products aren’t cheap, they are very overpriced and not affordable to the general public at large.
