RBBR V.1 (Reds Bullpup Battle Rifle) (Update: Internal Pics)

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

This is my first (working) bullpup, and I am totally happy with it. Now, I don't want to hear ANYTHING about how it should have an internal mag pusher, nor about how it shoots connecters. It is perfect the way it is. :-) Again credit goes to Sharir1701 for his FPMG. I think I might ask him if that can be the official "The Red Book of Westmarch" mag...hmm... Go take a look at the internals!

Great looks
Great feel
Nice 'n light
Quick ROF: 30 rds. per minuet
Good range: 30 - 50 ft.
Has carry handle
Mag is effective, quick to load into gun
10 rd mag
Room for two extra mags, behind the first
Sights work
Large pullback
Bullpup mech never fails

Mag takes a long time to load
Mag does not hold A LOT of bullets
Carry handle is rather frivolous
No cheek rest

Well, what do you guys think? Do you think it needs a video? This gun is a great gun muzzle loaded too, and my younger bro uses this as a rocket launcher, as his arms are not long enough. The "Sneak Preview" provides a view of my KAP-40 V.1...what do you think? Pretty awesome huh? Remember, if you want to know more about K'NEX guns, build a ton of them, and find a mentor. :-)

    Well, I am under the impression, good sir, that all guns are ambidextrous (you can hold them in either hand). Such is the case with this one.

    I see you getting better every day but you've come at a point now where your guns should have a pin guide, pin with a female ball socket on the end and an internal magazine pusher.

    Explain to me what you mean by "pin guide?" And I have no ball and socket pieces. As to the IMP, I chose to to use them because that are not as effective overall.

    Internal mag pushers are not less effective. You could say they are harder to make good, but a good IMP should be just as good if not better than any old external pusher, plus the benefit of it being internal, making for much better comfort. Don't knock it 'till you've tried it man...

    Well, your wrong there, IMP's are not more effective. If you have a mag pusher, that is still in the mag (it does not come out) but still has a rod coming out, it is easier to fix jams. If you are using an IMP bendy rod, you have to take apart one half of the mag to fix a jam.

    Define "effective"... With a good magazine there shouldn't be any jams, first of all, and second, I never said anything about bendy rods. I despise bendy rod mags, that's why I always try to make mine with rubber band where possible. The only differences are aesthetic: looks, comfort, compactness etc.

    Effective: Successful in producing a desired or intended result.

    Anyway...Well, I don't like IMPs, because they are harder to fix when (and if) they jam, that's all.

    By that definition any mag that successfully pushes the bullets up, even the worst possible mag, is "effective". Not really proving your point...

    But I'm telling you, it shouldn't be too hard to make a mag that doesn't jam at all, it just takes a little bit of work. Plus, I don't really think you've given IMPs a fair shot. just try out one my IMPs and decide for yourself. If you say they're too complicated or something, they really aren't, but never mind. I also think you're just fearful of the unknown, as we all are. Just try it out.
