Homemade pistol caliber semi auto carbine?

Has anyone tried to build their own semiauto pistol caliber carbine? Looked at some of Luty's designs and figured they could be made in semi auto instead and have the receivers welded together to prevent the easily convertible issues.
 
It has been done.
Beware of the SFSS.
Make really sure that it is semi auto and not readily convertible to auto.
 
There is no legal requirements to send a gun to the SFSS... As long as it meets ola and barrel length you should be GTG.

OP didn't mention restricted or non-restricted. If restricted, it is going to be reviewed by SFSS.

If intended to be non-restricted, and if it ever attracts attention, it will be sent to SFSS. If it is determined to be readily convertible, it will be classified as prohibited.

If only there was a definition of what "readily converted" was...

You're are right the op didn't mention if it's intended to be restricted or non.... The op did mention taking care of ease of conversion issues.
I don't find my guns attract a lot of attention. At least not the kind that gets them sent off to "the lab". Again, there is no legal requirements to submit NR firearms to the rcmp.
 
The current standard for conversion is the Hasselwander decision. Such as it is. As I understand it, the conversion must not require difficult to obtain parts, specialized tooling, or need more than an hour. That is not definitive, but there are a great many semi autos that are not deemed convertible under this standard.

Did anyone say that there was a legal requirement for non-restricted firearms to be sent to the SFSS?
The SFSS has demanded the submission for inspection of a semi auto, long barrelled carbine. Legal basis for such a demand? I am not aware of one.
As far as attracting attention goes, ever seen an illustration of a Luty gun?

You could build a non-pistol lower for a Mech-tec carbine. You could use some of the pistol lower parts. If the lower had no slide rails it wouldn't work with a pistol upper.

An 80% 1911 frame could be finished so that it would fit the MechTech CCU, but not accept a pistol slide. The slide grooves could be cut only part way, just enough to slide into the MechTech. The MechTech barrel is short enough that the resulting carbine would be restricted on the basis of barrel length. A replacement longer barrel would change that. The resulting firearm should be non-restricted; barrel would be over the minimum, and the receiver would be non-handgun original. Anyone doing such a project would be well advised to do the barrel first, so that there would not be a time when the thing would meet the definition of restricted.

The idea was to go non restricted with a 19 inch barrel, make a semi auto trigger group and weld the thing together in order to make it a #### show to attempt to disassemble and convert it once fully assembled. I figure if they literally need to cut the gun in half to get at the trigger thats not easily convertible. Obviously mags would be 5 rounds unless the design was modified for pistol mags.

The SFSS made some demands on me. I blatantly refused... They made some thinly veiled threats. I ignored them and it all disappeared... And this was over a child entry.
We are our own worse enemy at times. With this submitting magazines and NR firearms. It doesn't need to happen and is a great mystery to me why it does.

Agreed. Which brings us to an modified AR15 9mm upper with a Kustom lower that won't fit a normal upper. Of course this isn't built from scratch. The homemade simple blowback designs are obviously problematic, you can cut welds with a Dremel fairly quickly. Designing a semiauto 9mm carbine from scratch would be way over my head.

If you are thinking about open bolt, it is really difficult to prevent conversion, in less than an hour, with common tools.
 
What about building something around an Ar-15 trigger group. Use a trigger pack like the Timney or trigger tech to avoid the easily convertible argument. Could be blow back with a floating firing pin.
 
Thanks gentlemen. I guess I'll need to spend some time complicating the design a lot more to avoid "easily convertible" status. Back to the drawing board for me.

According to the RCMP lab guys anything after having been worked on for two thousand hours with the latest NASA designed CNC machine is easily converted which is why they restrict and prohib so much.....:runaway:
