Google translate of this: http://www.military-informant.com/index.php/army/3455-1.html, very little concrete info in it. Here are the highlights
"For the very first time, the new special purpose assault rifle AS-1, was publicly shown. The Kalashnikov Corp demonstrated these weapons, which were initially developed at the request of the FSB for special operations, to the professional community at the “Innovation Day” expo – AS-1 in 5.45x39 mm and AS-2 in 7.62x39 mm.
Later on, the AS assault rifle may be included as an armament competent of the indigenously developed Ratnik “future soldier” system.
The main characteristic of the new assault rifle is the so-called “bull-pup” configuration. According to an announcement by a representative of Kalashnikov Corp, in addition to the more traditional rifle configurations, the company will develop and mass-produce such “bull-pup” designs, where the hammer part of the fire control group and magazine are located behind the trigger."
The article goes on to describe the history and benefits of the bull-pup weapons, focusing on the Steyr AUG.
It ends with: "Unfortunately, at the moment, we lack any details on the design and specific functionality of the AS-1 and AS-2 assault rifles, but hope that more information will be disclosed and available soon."
