Hmm...

Does it have to be a springer? A bullpup could be done with an air gun where a tube connecting the air tank to the barrel goes back to the stock behind a clip.


No. I think that an Eyes of Fire-esque regulator system would work like a charm, a precharged tank in the foregrip, and a dual-regulator output, and on firing, a Magstrike valve opens, releasing a burst of air that fires the dart. As the dart fires, some of the gas is siphoned back thru a tube hooked to a hole in the barrel and opens the breech thru a piston-tube that has a very weak extension spring that shuts it after the pressure is released by a hole in the piston tube. It is like an AR15 action, but with valves and air instead of firing pins and gunpowder.

Halfway, the gun would be more compact, easier to use, and lighter. And if done right, can kick a Magstrike's ass.

Nerf Haven is some kind of fantastic Hivemind, I was thinking about bullpups a few days ago

What if you just had a very extended trigger assembly, slice the trigger and pistol grip drag it up front, and use some machined plastic to replace the long end....I suppose the idea is a bit convoluted


The Birdy Avatared guy has my thoughts down in a manner, I was thinking though of trying it on a BBB and A2k or 3k but more of a ergonomic shell and not the bull-pup craziness.

But it feels like the best way to approach a bullpup design would be to stick with an Air system. Which the Airsystem would allow for a stream of air to be more constant to compensate for a longer barrel. Just look how well A2k and Air Bladder's (magstrike or powerclip... whichever) work well together.

I'd like to clarify that by definition a Bullpup is a firearm which has a magazine port rearward of the grip, not the firing mechanism.
Chop off some of the longshot's front, move the grip and trigger assembly forward, call it a day.

1. Bullpup homemade Link .

Yeah, not really bullpup....I just called it that because it was "bacwards", sort of how one thinks of a bullpup rifle. The 4bp used to stand for BullPup. Now, I'm just saying that it stands for Backwards Plunger.

Even though JSB mentioned the RFR in the first few posts, no one has suggested making it bullpup? Chop off the fake stock, the plunger and catch are already near the front so putting the trigger and priming method nearby wouldn't be too painful (in my opinion), make a grip near the front too. Granted, it's still going to be a shitty gun, but that's probably your best bet for conversion. If you're just going to slap together a slew of different pieces and stick them in a shell, you have plenty of other options.

Seriously, the easiest thing I can think of is making a custom shell and dropping in MS internals. Full Auto, Semiauto, depending on how good your trigger finger is. Also, it's a bit easier to fit into a bullpup design.

Well take the longshot, think of it as the m16, the machanics are in the middle. Then think of the enfield or stauyer AUG 77. All the machanices are in the stock, itheya're both a bullpup design but when they were made they each had major flaws, and thats how its going to be trying make a nerf gun bullpup. I give you props if you can make one!

From the firing video the Raider is a bullpub gun, but its a pump action so I don't know if it counts.

The Raider is not a bullpup gun.

Yeah I know what a bullpup gun is. It feeds the magazine behind the trigger. Look at the Raider video, the drum is behind the pumping handle.

EDIT: Sorry, I didn't notice the trigger being pulled in the video. My bad.

Obviously you have no idea what a bullpup is if you think the raider is one of them. Does the magazine on the raider feed behind the trigger? No.

Ok, lemme show you my proof of concept for making a Magstrike Bullpup.

LS shell is used as a point of reference, and it fits Magstrike internals well if you shave enough out and add what is needed where it is needed. Except, to bullpup it, you'd need to increase the length of the buttstock.

Excuse MS Paint, please. I try, I really do.


I may try that, though with a conventional magazine setup.

3 things:

1. that is way too unweildy(sp?)

2.Why in the name of ForsakenAngel24 would you hack up a perfectly good LS to put an even shittier gun into it? If someone built that.....that.... thing I would sit at my PC thinking the following and muttering it for the next week:

"What..................................the..................................fuck. That was even more retarded than the Vulcan alligator thingy.

3.What in the name of Popeye's Chicken happened to my dual-reg idea?

That was exactly my point. It works, but is it worth it?

TBH, I'd make it just to prove that it can be done. I like the rifle design of the LS more than the... Whatever the hell that is of the MS, anyway.

Also, I may have a failed attempt at modding an LS which ruined quite a few components somewhere, meaning free shell.

If not, my cousin's LS is bound to break soon.

1. Yes, I will post pics as soon as I get enough acetone to dissolve the superglue, why the fuck did I do that? Don't answer that.

2.Okay, I thought you were serious, but it really was a POC sketch. Phew.

3. I should have a writeup of what to do to make an LS pocket-sized, thing is, it can't use clips. And it is in the shittiest Nerf gizmo ever, the LS scope.

The P90 isn't a bullpup. It just has a helix mag, but it still feeds infront of the trigger.


No offense, but it is fed by a top-magazine (not a helix magazine like onCalico Carbine/SMG ) the with a ramp that slides the rounds into a forward position, then the shell is sent out of the front handle. The rounds are chambered behind the handle, so technically it's a bullpup.

The darker spot towards the back of the magazine is the ramp where the rounds are chambered.

I may build it, just to spite you, Nut :P


Though, since you bring up the Vulcan, I may try coming up with a system that electrically cycles the bolt, allowing for full-auto... Time to get the engineer gloves... And a pocket protector.

I can has bonus points if I bullpup it?

Yes, as long as it shoots decently (it shoots over 50' flat.) If you get over 90' flat, I will applaud you, literally. And, a pocket protector? Seriously? :blink: :blink:

bigred1rifeman, you are right in that the P90 is bullpup, but the shells eject out of the bottom of the gun, you were thinking of the FN2000.

And how the Popeye's Chicken did we end up arguing about the P90?!?!?!?!?!!?!?! Please, people, stay on topic.

Off topic:
I may build a Nerf railgun, it may be massive, and it, in theory, should break the sound barrier. Yes, with a nerf dart. It is based off of the R2 LAARK.

Posted Image

It is a scrapped project, until I get capacitors, it is doomed.

Sorry for derailing the thread. Oops. On topic, I would love to see that be built.

Railguns... Seriously.. go die. This forum started out as, and mostly still is for, practical mods for warring. That is far from it. An awesome science project, but a stupid ass concept thread. Please, go spend hundreds of dollars to lug around 20 pounds in capacitors and batteries and wait in between shots. I think I'll barrel tap you while you're waiting.

PS. Your dart will never break the sound barrier. Just stop.

Edit: And schitzo, a MS Paint diagram is possibly the furthest thing from a proof of concept.

Okay, I think I've heard and read enough.


A word of caution to anyone who's "gonna" build something, or "planning" to build something, and has enough audacity to post it here on NerfHaven.

I'm going to monitor what everyone is "gonna" do. If I don't see anything resembling progress on these things in the next few weeks, I'm going to start deleting accounts. That's an alternative way to clean up the forum.

Anyone who remembers the homemade Nerf "shotgun" thread knows what a mindfrack reading about "plans" and "intentions" and "concepts" can be.

Some of the theories here are not just amusingly absurd, but I'm sorry, they are as impractical as they are dumb. Why would you put a barrel on a MAGSTRIKE (powerclip)?! It will perform better if you shoot darts right out of the clip/magazine, a barrel on a Magstrike is even more impractical than the extensions on the Longshot and the Recon... even if they do "look" good.

About the ONLY practical Bullpup designs for Nerfing would be an air-powered setup to shorten the weapon wtihout sacrificing barrel length; Our old SM5000 mod and tank relocation is an example of shortening a weapon while maintaining optimum barrel length. A more extreme tank relocate would shorten the weapon even more, while keeping premium barrel length. A springer is even more difficult to bullpup, since most of them depend on a plunger going back a ways to store air. Perhaps a reverse plunger (going forward) and pushing air 180 degrees (tubing or a u-fitting) is the only way to get true bullpup configuration, but that's a whole lot of fabricating.


You guys want to talk about stuff like railguns, go to Foam Universe. They're "experts" on stuff like that over there.
