Lol, I've already done up the design, I was just hoping to hear back from Wizard of Flight. I sent him a PM asking if he'd mind me posting a modification to his drawings, but I haven't heard back yet. I was going to try and hang out a couple more days, but I am keen to show it and get some feed back.

Thanks for the input Spawn Camper, I can't seem to see your picture though. :unsure:
 
So do you think you're gonna go the full 48.8''? The one i've been working on i've brought it down alot. With those dimensions it just seems like it would be way too big for normal humans. But heck yeah I say go for your own design. Creativity is never frowned upon here :)

well it was working last night, now its forbidden =P

Forbidden? Now I just want to see it more! :D

I'll be going with a full size bulldog (my own design. See drawing). I bought some plywood on the weekend with the intention of doing a couple of full size cutouts just so we have some decent reference here on the boards as to the M90A's full size. I'm not sure when I'll get it done but I'll do a cut out of the M90A and the M90A- Bulldog for comparison.


Before I go on I'd just like to mention something. It may seem like I'm going a little bit overboard with sizing and reference material and the like, but I think it's important to build believable props. I'm one of those guys that when I see some cool gun in a sci-fi or action movie I want to know how it works, what ammo does it take, how many rounds does it hold, and so on. And if I see something that just isn't believable, then it puts a fracture in the realism of the rest of that world for me.

Another reason I want to go to this much trouble is that I'd love for us to start to get a standard sizing to our props. How cool would it be if when large groups of us get together that all our weapons are sized the same yet made in completely different parts of the world by different people. That to me would be cool. But then I like the little details. :)

Also whether or not you know it every firearm ever made has a rich, interesting and sometimes bloody history of development many years in the making. Just like everything in our world.

So here's my design based on Wizard of Flight's blueprints of the M90A from Halo 3.

M90A

Caliber- 8 Gauge Magnum
Capacity- 6 Shells
Length- 48.80'' But has a removale stock.

As seen and used in Halo 3.

M90A-C (Concept)

Caliber- 8 Gauge Magnum
Capacity- 4 (+1)
Length- 42.20'' But has removable stock

The first design by Pvt. Juliet in an attempt to develop a more CQB friendly shotgun. Design abandoned as it yielded unsatisfactory results.

M90A-BD "Bulldog"

Caliber- 8 Gauge Magnum
Capacity- 4 (+1)
Length- 37.40'' Stock not removable

Still in development. The M90A-BD or Bulldog as it became termed by it's designer Pvt. Juliet, was the first success by it's designer in an attempt to develop a shotgun that packed (nearly) all the punch of the M90A but in a smaller but more practical package. It was originally under taken as an attempt to create a pump action bullpup, but this was abandoned as the pump remained creating excess length. But what was taken away from it was placing the loading port and it's inner workings further back into what in previous models had been the removable stock (see further details bellow on the removable stock of the M90 series), shortening the overall length. Due to the large size of the 8 gauge round it was considered almost a gimmick to include a removable stock as it is almost impossible to fire accurately without it and only serves the purpose of making the weapon easier to stow.

The shortened barrel is compensated for by increasing the choke,

giving the weapon a tighter grouping of it's pellets despite it's shorter barrel length. Reports are that it's accuracy and range are equal to that of the full barreled M90A. With a tighter choke unfortunately comes the side effect of increased recoil (contributing to it's nick name). But with the shorter barrel, recovery time between shots is expected to be the same as the M90A's.

With the shortened barrel comes a decreased magazine length, a necessary sacrifice for the reduced overall size. This is nearly overcome by the operator chambering the first round and then loading another giving it a total of five rounds (4+1).

The model is awaiting feed back from the 405th Infantry Division and is hoping to go into limited production later this year.

Note: Removable Stock on M90/MKII/A's

Halopedia M90 Close Assault Weapon System said:
The M90 series of shotguns have another feature as well: all have a detachable stock, allowing the shotgun to be used at even closer quarters. If you look carefully at the M90 (any game), you can see that the stock is held onto the actual firearm by a "pin and button" system.

At least I figure this is what the Halopedia article is refering to. Full article here-

Sooo, thoughts? :)

Those who don't know much about shotguns may be inclined to think that an 8 gauge sounds small especially in comparison to the 12 gauge commonly used in real life. Not so. The 8 gauge magnum round used by the M90A measures an impressive 88.9mm (3.5'') long and suits a bore of 21.208mm (0.8350''). As shotgun gauges are worked out on an odd system of how many lead balls fit in that diameter to equal one pound (see the table bellow for clarification) that makes it noticeably bigger than the diameter of the 12 gauge- 18.527mm (0.7294'').

Sounds like a deer slug which is about the scariest thing that can come out of a normal shotgun nowadays (besides elephant shot) at about a solid 1-1/2 oz of lead. They leave holes roughly the size of a golf ball in walls.

Nice design, you have put a lot of thought into. I'm impressed!

Now lets see some building! :mad: :D

All kidding aside, Great job.
 
Curse these stupid at-work server restrictions. I can't see the pics! :mad:

I want to see what you've been working on for this. Guess I'll just have to wait until I get home *sigh* :(

SII, you do indeed want to see these designs, they're pretty freeking awesome. Can't wait to see this custom variant.

I've also been eyeing the shotty as a possibility for my next build, and a chance to dust off my woodworking skills. I'm going the boring route, though, and just scaling down the standard M90 to fit myself, and I'll probably notch the slide to clear the ejection port.

Bravo my friend! Excellent work and I love your designs. Also i'm stoked on the idea of a pretty universal sizing. Very good idea. The bulldog looks badass I can't wait to see it come together.
 
ok this isn't the picture I first tried to post but it is still important
pump_action.gif


ok what this picture shows is that the bulldog is the only capable version of the shot gun because the end of the tubular magazine has to be close to flush with the breach of the barrel

this is the image I meant to post before
neostead_parts.jpg

this is the neostead and it IS a bullpup shotgun, it also has the tubular mag on the top as like the m90 so you might take some innovations from this, also should note that the pump is backwards and to use the action you have to pull out the pump and bring it back

my proposal

I'd hate to be a deer. ;)
(Nice AV BF. They letting you guys import Cubans over there yet or what?)

That's all you people care about isn't it? Builds, builds, BUILDS!!! :p
(Thanks Lee ;) )

Let us know what equation you use to scale it down Loses, I'm very curious to know. When I get around to doing some cut outs for sizing I may do some of the other weapons too. See if we can't come up with some over all size reduction for the weapons if it's warrented.

As for the ejection port, why not go with something like Spawn Campers idea of moving it back rather then notching the slide. I do like that end part that seemingly does nothing. It's got a big screw, it must do something!:lol:

Thanks man! I think building might be a little while off though. I want all the bells and whistles for when I build this which means a soundboard. But from what I've seen here there's no one that does one for the shotty. I used to lurk on a lightsabre builders forum and there was a guy there that did blank sound boards that you could load sounds onto via a usb stick. I might try and track him down. Unless someone has some other suggestions?

Not over yet. ;)

Sorry, I'm not sure I follow why the bulldog is the only capable version.

Yeah I saw this while I was researching the designs. When I started drawing with a bullpup design in mind it quickly became apparent that while using the M90A as a base I couldn't get everything in a position so that it'd work as well as make it shorter, as well as give the sort of look I was hoping for. And let's face it the Neostead may be a innovative design, but the thing's ugly as sin. The magazine postioning is one of the main things I think the developers took away from it (as well a the dual mags, at least in Halo CE).

Can't see why something like that wouldn't work, depending on what you want to do. This wouldn't work for the load/eject system I have in mind though. I intend to have the end of the loading port (end closest to the barrel) be postioned in line with the begining of the ejection port (end closest to the butt). That way I'll be able to feed a couple of rounds in which will drop down into a magazine in line with the ejection port. I'm hoping to use a leaf spring or something to help keep the cartridges from rattling around in there.

I'll draw up a basic picture if I get a chance to give you all an idea.

All that I'm going to do is to tinker with the scale until I can get it close to these dimensions. I just measured myself to find a comfortable grip.

That was a good idea... if someone scales armor to fit, weapons should be the same... hate to see master chief jr using master chief sr's oversized rifle, shot gun, etc...

Only WH weapons are suppose to be obscenely large...

Loess I'm hoping to do those scaling cut outs this weekend. Instead of one of them being a bulldog I'm starting to think I'll do a scaled down M90A. If I can come up with a scale similar to your dimensions do you think you'd be willing to use it? More importantly can you wait that long?

The only thing with that is when we all get together and stick our weapons on the same rack. I'm really hoping to get some sort of standard scaling worked out off the Halopedia(/Bungie) measurements, one for adults and a scaling range for kids too! If we just put in some work together I'm confident we could pull off a 405th weapons scaling system for our builds. :)

I's finally gots to see dem der pics (checked out this thread last night at home). Nice job on the revised schematics you made there, buddy! It would be kewl to see any of those variants built into a physical model :D

BOLD # 1: That might be a good idea. Not unlike what I've done for both the SR and now SPNKr; downsize the model to be in scale with an average-sized person. Helps to make it not look disproportionate or anything.

BOLD # 2: That's a fantastic idea, dude! I'd definately be in for helping out with that. We could do it :cool:

I'd love to see some scale mock-ups, they'd really help me with my build. I can wait a bit, I'm vacillating between doing the shotgun first, or a slight modification of Hunter's H3 concept art rocket launcher first. I guess my biggest stumbling block on this has been procrastinating on finding a higher-res version of WOF's blueprint to run off at 1:1 to the scale I want.

SII, it'd be fantastic to start getting some general standards for weapon scaling, that'd make us look even better when we get together in a big group.

Ya think? :p lol

It was juliet76's idea, though. Want the credit to go to the right person, after all ;)
