Picture of My K'nex A.R.M. Gun (Awesome Removable Magazine)

This is my Foldable K'nex A.R.M. Gun (Awesome Removable Magazine).
It's my second K'nex gun instructable, but the first one sucked and was a complete disaster, so i took it down.
This gun is much MUCH better than the last one, it's amazing, to my opinion. I love this gun so freak'in much !!!
I hope you enjoy this gun as much as i do.

removable mag
powerful, got it to shoot 73 ft
easy-to-use ram
comfy handle
sturdy mag house
sights, pretty accurate
non-breaking, comfortable trigger
nicely shaped magazine
looks good, shaped like a pistol (if you ignore magazine)
small, easy to store and transport, comes in handy in a k'nex war, doesn't use many pieces
mag ram never breaks because it stops just before where the ram goes

long time to load magazine
handle isn't very sturdy
takes a long process to fold

I would give this gun a 7.5/10

can i review this

you're a bit late, and this gun is a bit (a lot) outdated, but if you want to, sure, knock yourself out.

mulletman6 (author)2012-06-26

Kool - i shal build this tomorrow and let you know what i think. I still wanna build the ZKAR if you have any internal pictures of it?

Sharir1701 (author)mulletman62012-06-26

word of advice - don't build this gun. sure, at the time i thought it was cool, but it really wasn't back then, and it definitely isn't now. just spare yourself this crappy gun. it's the type where you have to cock the mag pusher and let go in the gun, and if you take the mag out after you've released it in the gun, it will explode in your face. forget about it. if you want a compact gun you'd be better off with the S2. i think it uses less pieces too.

how does it fold???????????

Back at the time i considered that as foldable. Basically, the handle detached at one place and reattached at another, but it was really bad, so i took the pics and vid off. Ignore the place it says foldable...

ok cool gun anyway its awesome

SomeAsianKid (author)2011-10-11

do the orange/black connectors need to be broken?

Sharir1701 (author)SomeAsianKid2011-10-11

no... i just used broken ones cause i didn't need their other end, and it's nice to use broken ones i already have and don't need instead of full parts.
did you or are you building it ? if so, i'd love to hear how it works for you...

soldeir 9 (author)2011-10-10

looks really kewl, the mag is awesome!, and since it is remouvable, its just that much more optional! :D

bullet tooth chris (author)2011-04-20

was that a camera mount that you made out of knex in the second video?

yeah, but it's kinda lame. nice spotting though !

DJ Radio (author)2011-04-15

This is pretty sweet, although I think the folding is overkill. Nice mag storage idea.

Sharir1701 (author)DJ Radio2011-04-17

i actually agree... the folding is a little over-doing it, but i think that some people out there might need it... ;)

agent harmsy (author)2011-04-15

It's almost like an FMG-9 pistol! Nice work.

~KGB~ (author)2011-04-15

beanieostrich (author)2011-04-15

Looks cool, but looks more like a messed up TEC9 =D 5*
