Well I've been wanting to do another custom gun build(titanium 22/45 just waiting on a grip frame) to have a cool little plinker to play with.And being the best way to piss off a liberal is to have something that looks like an SMG,I've settled on a black bullpup.

To start I eyeballed an old Cooey 64B to mess with,since the receiver is very small,simple and easy to mount it seems perfect for this,and nothing says CANADIAN like having a Cooey.Due to guidelines this action will just be used to mock it up,then i will mill out a brand new one and send the whole unit in to be assessed.It will wear a minimum length + a hair barrel, or depending on the way it looks it may wear the short barrel and be just a restricted range toy.The only parts that will not be made by me will be the bolt,barrel and the magwell.The trigger setup will be totally different and the action will not be able to fire outside of the stock.It will have a top cover/rail to mount an Eotech on and hide the top of the receiver/barrel,and a bottom rail to mount a vertical foregrip on.

So for part 1 it's just getting things together to get started on this project.

Step 1:Action

This is the action i will be mocking it up with,an old Cooey 64B receiver and possibly a reworked 10/22 barrel

Step 2: Material

I'm gonna go with an all-metal build.Aluminum is easy to work with,lightweight and can be parkerized to give me that matte black/grey look i want.

So i'm starting out with a 2"x3"x20" block of 6061 that cost me $50

Step 2: Extended bolt handle
Since it will sit inside the aluminum stock,the factory bolt handle is too short and has more slop and play than i'd like..so a new one had to be made that fits tight and has the length i need to operate the action properly once seated in the stock.A2 tool steel was used.A rad was added for appearance and the end was lightly knurled for positive grip

I have no print or CAD drawing,i'm going to do this all by feel and innovate as i go.If you have any suggestions i'd love to hear them.

Now i'm waiting on some more tooling (ball nosed end mills and key seat cutters)that should be here this week to get working on the stock and trigger components.

Part 2 coming soon!
Give me some feedback on what you'd like to see!!

Very cool idea, but that'll get cold in the winter!!!
Are you going to mill it? Otherwise whats your plan on the shaping of the Aluminum?
Good Luck, and keep us updated:D
 
If you are cutting a new receiver, how about putting the cocking handle on the left side, like a FAL or XCR?
Depends on the bolt of course, whether you can drill and tap into the left side.
 
Well there is nothing obvious with bullpups. Cocking handle cannot be moved to the left side of receiver unless its moved far forward as well. Unless your leftie it will take your teeth off. Another detail needs to be addressed is shielding ejection port. I am talking from experience, bullpupped 22 semi will eject right next to your right eye and your will be sprinkled with hot gases and unburnt particles. Scope mount need to be custom built as well - you will not be able to find readily available 2.5-3" raised rail that is also barrel-mounted. Stock butt needs to be sitting on top of your shoulder as much as pressing against it or rifle will tend to tilt very uncomfortably. Thats it for now. Post pictures.
 
I have been planning to do the same project but have not had the time yet. I have a junker 64B just waiting to be used for parts. Instead of milling it out of a solid bar I was going to try casting the frame.
 
Did you alter, modify or shorten the original barrel so that it was less than 18" in length?

Better check your legal status.
 
I knew someone would bring that up lol. Anyway, when doing a treading job, what kind of shoulder profile on the bbl should there be? I would think something with a slight taper to help center attachments would be beneficial(like 118 degrees)? and tapering the attachment 118 would be a good idea too?

Here is one I made up for the kids with an 11.5" ER Shaw Barrel....Threaded end with an AR15 A2 Flash hider...and it's Non-Restricted......

The barrel was brought in years ago before all the export/import permit paperwork was needed.....It will be harder for you to get one now...

You don't have to wait until tomorrow, it is on their website:
"prohibited firearms include...
...rifles and shotguns that have been altered by sawing or other means so that their barrel length is less than 457mm (about 18 inches)..."

When you call them tomorrow, ask if a factory short 10/22 barrel would be acceptable if remachined at the breech to fit a Cooey 64b.

Your machined from a billet lower should be OK as far as the bullpup stock business is concerned, as long as the trigger mechanism is part of the unit. That would avoid any suggestion that a separate bullpup stock is involved.
 
Well after reviewing the CFC's site,i'm gonna start with a new barrel.
Is milling the chamber off and adding a bunch of oddball cuts enough that i can just chuck it in the garbage or does it need to be completely destroyed?

Actually, simply removing the barrel should have been sufficient. A short rifle barrel isn't a prohibited device. A longarm with a shortened too much barrel is a prohibited firearm.
 
Well it's done now,so i'll just chuck it.
Thanks for the heads up,i'd hate to have put all the work in and have them say it's prohib and keep it.

I would just keep it around in case you have a future pistol project. I have made use of a couple of barrels this way.
