RMC V.1 (Red's Magazine Case Gun)

About: K'NEX gun builder here at Instructables. More or less retired from the community, but I still pop in now and again.

Well, the RMC came out of a at least two weeks of having the "K'NEX blues." I could not come up with ANYTHING to build...and it was VERY frustrating. This gun is a FANTASTIC gun, and was great fun to build and to play with. It is rather big, but since some people on 'ibles seem to LOVE over sized guns, that should not be a deterrent. Lets look at some pros and cons, shall we?

Epic looks (IMO)
Great range: 45 to 50 ft.
Two extra mag "cases"
No sights
Mag goes in the top
Simple mech
comfy handle
Medium accuracy
Only requires 4 broken pieces (that is, if you only are gonna make one mag)
A ton of fun to shoot

A bit bulky
Can misfire (but this HARDLY ever happens)
Not a model
Only a 6 rd. "mini-mag"

So, what do you guys think? Oh, do you have any model ideas for me...? XM8 perhaps, the other ones on this sight stink.

    I really like this idea. I don't care for a shooting Knex gun, but for someone who does this is probably very cool and would be great for a war!

    Good, I'm glad you like it. Oh? You are not into shooting K'NEX guns? Funny, I don't know how many of us here on 'ibles "is not into" shooting K'NEX guns. But, it does not really matter in the scheme of life.

    Yeah, it's just that I don't think they get enough solid range to actually be fun to shoot, whereas airsoft guns can get pretty good range before the rounds frop off.

    There are plenty of options:
    Bendy rods
    Some guy made louis xiv's semi auto into a small internal mag pusher mag.
    Try a BAW like mag
    Desperado mag

    Dude...its a concept gun. Its not supposed to look epic. As to the mag pusher...what would you suggest? I have never seen a better one that the one I used for that size of mag.


    It's very cool. I can't say much more than TheAwesomestDude said. However, aiming will be a bit hard with the mag on top, though I think that can be solved by adding sights just on the side of the gun (a little like the Bren has).
    Keep up this great work
