WolfBodyArmor shows the second version of the K-SMG-1 Airsoft GPCQB, the "Ferret" MK2... "This is the Mk2 version of the Ferret smg, with many improvements over the original. Still using kwa mac11 magazines, but now with a lower firing rate of 800 rounds per minute, and an under mount shotgun which takes APS cam870 shells. The shotgun is fired using a forward mounted button.

The mark 2 design also now sports a full length top rail for optics, a polymer lower receiver to reduce weight, and a redesigned wire stock to reduce size when collapsed.  The charging handle has also been redesigned entirely to eliminate noise from rattling, and be easier to grab in general.

Its compact size and high firepower make it a true general purpose cqb weapon for nearly any game scenario."
