Red Army Airsoft goes over the fine details of the ICS Airsoft CXP-MARS PDW9 which is one of the preferred CQB AEGs for those looking for alternatives to the G&G ARP9 AEG with ETU. For Russian airsofters, this is available at the Airsoft-RUS store and this comes with a built-in MOSFET and a 9mm-stule AEG magazine.
