Here is the take of the Evike.com on the EMG Helios PDW M2 Sportsline G2 Review which is available in black and tan at their store... "The G2 gearbox developed under collaboration between Matrix and S&T offers features such as a microswitch trigger, improved steel gears, full steel teeth piston, and aluminum cylinder. The inline MOSFET features over discharge protection and the electric trigger features a magnetic sensor for improved responsiveness.

Based loosely on the layout of the M16 service rifle, the Knights PDW offers similar controls making familiarization with the weapon system a non-issue. With ambidextrous features, the Knights PDW platform gives shooters the maximum amount of options with weapons manipulation and deployment. The short barrel and folding stock make for a very compact profile, ideal for close quarters combat and for arming vehicle crews."
