Ok, I don't have any pictures drawn up yet but I thought I would post an idea I had on a shotgun to see if anyone would share an interest.

See if you can picture this...

It would be a bullpup, pump-action, tube fed, shotgun with the following features and characteristics.

-Options would be 20" 8 shot version or an 18" 6 shot version. 2 3/4" or 3" shells could be used.

-Magazine tube would actually be located above the barrel along with the hinged loading gate which would close rather securly to prevent nausiating gases from entering the users nose.

-Shells would be cycled just like a standard pump but they would be drawn down into the chamber and ejected from the bottom of the weapon.

-Trigger linkage would be smooth and consistant, made from a solid construction.

-Sights would have a few options. A standard bead sight would be securely mounted onto the end of the magazine tube also I standard picatinny rail could be mounted from the reciever and stradly the magazine tube (similar to the P90 sight.)

-The forend itself would be interchangable with any 870 forend although the way in which it was mounted would be slightly different.

-I have also thought of maybe a removable magazine tube similar to that of Zeus paintball gun.

For those of you who aren't familiar it works very much like a P90. The user would simpy reach the reciever end of the magazine tube and press ambidextrious release tabs to free the tube. Then the user would simply lift the tube up and slide it toward the rear of the weapon until it was fully removed.

Overall, the design would be based on a typical pump shotgun action but it would not be a "stock" that you simply insert an existing action into like virtually every other design.

Is this a dumb idea? Any takers?
 
I'm having a hard time imagining it. How about a diagram or something like that you can attach. Just something simple pointing out the basic layout.(MS paint or anything similar would be helpful.) Where would the trigger be in relation to the pump?

To answer your question, it would have to be pretty close. I obviously haven't accounted for actual measurements but I would say that when the bolt is in the open position, your hands will be as about as close as they can be.

Mossberg made one of those a while ago (more or less), search for Mossberg bullpup

It's ugly as sin
 
It's a solid idea, and I'm sure you could do a better job in the looks department than Mossberg has done in the past. I've thought about that design before, but picked another route to go when I started my first shotgun project.
 
It is official, I are old.

DO NOT make this thing in 28gauge.

You just thought the War of Northern Aggression was something, you make that thing in 28 gauge and even think about going on a Gentleman's Quail Hunt in Gawgia and all hell is going to break loose.

Forget Doves, small game, Skeet, 5 stand, Sporting Clays, Short Trap, Introducing new shooters, Instructing new shooters...

and others ain't cotton to the idea.


Awerbuck.
Awerbuck that teaches defensive shotgun use, is fine and dandy with a SxS shotgun and ...

Mentors & Elders, I'm a coming, I hope y'all got the Quail Coveys lined out, and the dawgs ready to fetch.

:D
 
Steve,

Louis thinks highly of the Neostead. 8^)

Of course, it's South African and so is he... but if he could get one into the country here, he still wouldn't carry it on the road.

Neat idea---especially the "quick reload" process....But how about making it an autoloader...lots of developmenttime either way, but with an auto loader you can change the positioning of the hands, to better accomodate the bullpup design.

P.S. I've always LIKED the Mossberg Bullpup....Had a chance to buy one cheap recently, but didn't have the $$$$$$$$$ :cuss:
 
Thanks for all of your replies! I actually didn't realize the Neostead was such a similar design. Although I am not sure I like the idea of the dual magazine tubes and foward pumping, it certainly seems like it would work great.

Anyways, since there is no Neostead currently bieng manufactured in the US, there might be a market for something like this. Although I don't see any purpose in redesigning something that has already been done.

Any reason why no one is making a Neostead domestically? It doesn't seem like it would be violating the Destructive Device laws. :confused:


I was thinking of something that would point well and be comfortable and easy to fire. Asthetics would be important, since so many other bullpups don't quite have the natural feel.

I hate the look of the carying handles on the examples and your diagram. Make it a flat top.

A year ago or more someone was working on a bullpup shotgun design using a transverse-loading magazine like that of the FN P90 PDW. It would have held 20 rounds or so with the magazine on top of the barrel/action. Haven't seen anything else about it for a long time and can't recall who it was that was working on the design I saw. Just one more thing to think about...

Neostad got banned because of its high-capacity twin tubes. Twin tubes concept was for ammo-selection, ex. you could quickly choose between buck or slug.

If you make a single-tube USA version, and could keep the costs down to a reasonable level, you may be on to something.
 
These designs are similiar to a shotgun I was thinking of creating myself. Though I think I might use the reciever from a Ithaca M37. From the picturesI suspect that you guys have been playing a little to much HALO 2.

Noested is pretty similiar to the above designs and it is made in south africa. Shame it never made it into this country, the laws for importation and destructive devices are foolish.

The Russian shotgun mentioned about is called RMB-93.

another interesting thing about it, it you push the pump foward instead of backward to operate the action.

Interesting design, curious to know how the trigger would work considering its a bullpup design. Why not make it a 10 shot, take advantage of the bullpup and add the extra shells
 
Hey nice Spiggy, I like the contours of that!

So pdowg881, you want one with wood furniture and a flat top? It could certainly be done and that sounds pretty cool. I would have concerns of weight though, I wouldn't want the final design to be too heavy and unwieldy.

brentn, I see no reason why a 10 shot 24" barrel version couldn't be made. It would still allow for a lot of firepower in a decent package. Overall length of what, 34" or something? As far as the trigger, my stupid drawing doesn't show it but I would probably follow the example of the Kel-Tec RFB. The maker claims that they will have very good triggers although, the trigger linkage would have to be on one or both sides of the reciever to facilitate the downward ejection. There's a picture of the RFB's internals here...

Any links on the legality of the Neostead? Oviously, it can't be imorted since its "nonsporting." Couldn't a domestic manufactuer make a deal with the designers and produce them in the US? I thought DD laws only applied to semi-auto shotguns. Is this right?
