Heckler and Koch MP5 rbg with semi- and full- auto (and safe), and other functions
About this creation
The most popular family of sub machine guns in the world in production today*, the Heckler and Koch MP5 has a new member! the MP5 rbg!

*production of the Uzi has stopped

this new model features:
extendable/retractable stock with lock
p90 style trigger for full-/semi- auto switching (look it up)
detachable magazine
folding rear sight for quick and easy loading of rbs
working safety catch
working charging/cocking handle
rotating barrel for easy turning of rb cog (i'll explain later)
durable design
good looks
99.9% black finish

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.

Pics:








Stock extended








magazine detached








front sight








rear sight








rear sight flipped back to acess rubber band cog (basically, for loading)








Safety catch (on)









and off








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








pistol grip








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!

nice! I made a 15-cap. ingram mac 10. I shot it once, the primitive bar-lock mechanism jammed on the semi-auto stopper, the gun split in half, the rubberbands ripped the mechanism in half, breaking some snap connectors, and some of the pieces flew around 50-feet from where I was standing, about 10x the max range of the gun itself! I bring a new meaning to single-shot!

i got it! well, for full auto, he uses a gear where u can put in technic pieces, he made that, and in full auto, the gears turn slowlier because the wheel pieces hit a piece, wich causess a shock, and the gear stops moving for a little time, ok, still complicated, but just looka t the pictures, but this is clever and really drained trough hes brain i guess

You sad that you geared it up to 40:1. Is that the same configuration as your MAC-10?

ok, I understand that is impossible to explain how the mechanism works (with a look at your other guns who were ONLY semi-auto). But how does the stock lock in place? cause I couldn't find anything about the stock in your pictures. Overall, GREAT JOB!!!

Quoting Austen Cordero i am confused, so: the combination piece is moved back for full auto by the selector, but somehow when you pull the trigger it pushes the combination piece back and forward again for 1 rotation? I am confused on how the trigger and fire selector are connected so the selector moves. ?????
no, the combination piece moves with the trigger, and fire selection just depends on how far you pull it back, and the safety just stops you pulling the trigger

Nice, although i might add that RBG already stands for Red Blue Green, after the color coding sequence, nice job btw, you ought to see Mjr.Disaster's as well as mine, although i still need to update my new one with pics, still photoshopping the off color parts haha

There is an exception to your description of an SMG. The P90 fires a standard NATO assault rifle round.

Sweet design, looks a lot like an MP5 and is very functional. I would love to see a video of this in action.
