K'nex SMG.

This time, it shoots. Also, added stock for performance. Pretty simple design, and you want to use as many bands as you can on the ram rod. If anyone wants me to post, (even though I bet you could build it from the pictures,) let me know and I will. Shoots gray connectors.

Pros:
 easyto build
pretty sturdy
easy to use

Cons:
SOMETIMES fires two at once
occasionally ammo gets stuck in the barrel, but more bands will fix this.
Not so amazing design, you probably have seen something similar to this before.

 none of the PROS are actually Pros. you put in what it doesnt do. you need to refrase that, or else people (like me) will get annoyed.
eg. not hard to build=easy to build
not extra likeyly to break= relatively sturdy
not difficult to operate=easy to operate.
and also, those are not even Pros themselves. they are STANDARDS. like having a true trigger is a standard, shooting is a standard, not falling apart is a standard. not difficult to operate? if it is worth posting a slide show, then it needs to work without any problems, unless they are going to be fixed.
