extendable/retractable stock with lock
p90 style trigger for full-/semi- auto switching (look it up)
folding rear sight for quick and easy loading of rbs

as you have probably guessed, this variant of the mp5 family is a non-lethal member (rbg=Rubber Band Gun
This gun is one of the few guns that i have built that uses more studded beams than un-studded, although i may start to even out the ratio in further guns. the main reason for using stude is for a solid build without lots of gaps in.
this gun has to be my favourite sub-machine gun, although it is a close contest between it and the standard Uzi. The Mp5 family is used by almost all hi-tech military branches in the UK and US - the SAS, SBS (special boat service), FBI, Navy Seals, etc. this is because, although a very complicated and expensive gun, if well maintained, will be far more accurate and reliable than any other sub-machine gun on the planet (definition of Sub machine gun= any rifled gun that uses pistol rounds (eg 9mm) and incorporates a full auto mechanism, or something like that).
my version has a complicated mechanism of its own: a 40 tooth gear is geared up to some other gears at a ratio of 40:1, so every time the other end does a revolution, the 40 tooth gear (with elastic bands hooked on) moves along 1 tooth.
this means that you can have a working semi/ full auto mechanism:
The combination piece is the one shaped like a U in its side. this is connected to the trigger. when the safety catch is on, a ratchet is engaged to one o the gear wheels, stopping any movement in the wrong direction.
The mechanism is far more complicated than in the picture, i have just simplified it. (A LOT!)
One more thing: Sorry, but I won't be able to post instructions for this- its just too complicated. Please dont ask.
rear sight flipped back to acess rubber band cog (basically, for loading)
Safety catch (on)
magazine release lever (flip it back to release)
The barrel - press it in and turn it clockwise to rotate the rb cog at the back, this is needed because it can be difficult to turn the back cog when it is nearly fully loaded, and thenthere is a ratchet engaged for extra friction (always load with safeth on)
the barrel pressed in
the charging/cocking handle (sorry, not a great picture). it is on a spring so when you pull it back and let go it snaps back
stock butt (extended)
magazine - detached, obviously ;)
1st person view (loaded, you can see the bands on top (theyre yellow))
bands coming out from under the rear sight
rb cog (loaded). this is situated under the rear sight, which can be flipped back, if you didn't already know
this is what the lump between the rear and front sights is used for, you might have noticed it (if you havent, look again)
this is how far you pull the trigger for semi auto action (i dont know why the pic went red)
trigger in full auto position (again, the strange red picture)
Well, thanks for looking!
if you have any comments/constructive criticism, dont hesitate to post them!
