K'nex SMG II Submachine Gun

This K'nex gun is modeled after the Heckler & Koch SMG II, which was designed in 1984. They are custom-made and only about 60 of them are in existence today.

Features:

working slide (makes it much easier to cock and doubles rate of fire)
true trigger
removeable magazine (thanks to Oblivitus)
detachable stock

Drawbacks:

no foregrip
trigger guard needs some work (but I fixed it, look at the 4th picture)
no sights or scope
only  shoots about 20 feet

I will try to fix these problems if  I post it.
