I'm wondering if the barrel on the Norinco M4 clone has enough 'meat' on it to be cut down to 10.5". My concern is that the step cut into the barrel may make it a little thin where the flash hider would thread on.

Sorry to break it to you. Law is, if it's already restricted, you can't chop the barrel....rifle becomes a prohib. You'd have to buy a new barrel or have one made...."re-manufactured" doesn't count either. God damn our laws are stupid.

My understanding was that putting/cutting a restricted-length barrel on a non-res makes it prohibited and cutted a non-res, non-semi auto below 18.5" puts it into prohibited. However, considering that the rifle is already restricted and has a bbl length of under 18.5" it can be cut down with no change in status. I'll dig out my Criminal Code and have a gander but I'm putty sure that I've read on here of guys trimming down their barrels.

Sorry, but you'd be wrong.

The regulations dealing with cutting rifle barrels doesn't distinguish between restricted and non restricted. You can make from a virgin blank any length you want, and the only possible concequence is turning the gun into restricted.

You can cut back an existing barrel from a longer length to any length at or over 18.5 inches.

If you alter by cutting or any other method a rifle barrel below 18.5 inches, you've created a prohib.

It stupid, but it's the law.
 
Lots of guys used to cut down AR barrels until a few years ago when the law was looked at a little more closely. Now you will have to rebarrel it to 10.5"... Should be able to find a barrel for around the 220 mark I think. Badboybeeson was going to make some budget AR barrels, try sending him a PM.

Not quite

What firearms are prohibited?

The Criminal Code defines the following firearms as prohibited:

rifles and shotguns that have been altered so that their barrel length is less than 457 mm (about 18 inches) or their overall length is less than 660 mm (about 26 inches)

Why would they make the two different? I don't know. I guess using the same length would have been too easy.

Have a look at the CCC, not the CCC for dummys version the RCMP post.

(b) a firearm that is adapted from a rifle or shotgun, whether by sawing, cutting or any other alteration, and that, as so adapted,
(i) is less than 660 mm in length, or
(ii) is 660 mm or greater in length and has a barrel less than 457 mm in length,
(c) an automatic firearm, whether or not it has been altered to discharge only one projectile with one pressure of the trigger, or
(d) any firearm that is prescribed to be a prohibited firearm;

b ii) still gives the same barrel length of 457mm instead of the non-res 470mm
 
Cut a longarm barrel so that it is less than 457mm/18" and the firearm becomes prohibited.
It does not matter if the barrel was less than 18" to begin with.
The OP asked about cutting his M4gery barrel. This would turn it into a prohibited firearm. It would be necessary to rebarrel it to get the shorter barrel and retain restricted status.

I SUSPECT that the intent of the law was to criminalize the act of turning a rifle or shotgun into a sawed-off shorty. That is, start over 18", wind up shorter. But that is NOT how the law is written. The law does not differentiate between starting at over 18" vs starting at less then 18". Poor legal draftsmanship? Likely. There is a lot of it in the FA/CC. Doesn't matter though.
 
This exact same question was dealt with not 7 days ago with some of the smith's with manufacturing licences speaking up. Time to use the search function. It doesn't matter if the gun is already restricted, you cannot cut the barrel down under 18 1/2 inches. A gunsmith cannot cut the barrel down under 18 1/2 inches. A barrel manufacturer cannot cut the barrel down to under 18 1/2 inchs. He can however make a new barrel from scratch any length you want it. And as Alberta tactical rifle said, no gunsmith is going to risk his licence by doing it.
 
^^^^^What he said.

I just went through this with a restricted VZ 58.

I wanted it's 15 inch barrel shortened to 12 inches.

So to repeat, I wanted to shorten an already restricted rifle.

I had to have a brand new factory Lothar Walther barrel installed. A new registration certificate was issued with the new barrel length.

You can't cut down a restricted rifle barrel without making it prohibited!!!! PERIOD. End of discussion.

This should be made a sticky.
 
how would they know if its a replacement barrel or your old cut barrel ? no serial numbers on them and all parts are sold without registration or lisense. sorry if it something obvious im missing, im new to ARs and dont read much of CFC rules, lol.
 
That's why you register AR's as receiver only. The tops aren't then an issue and have nothing to do with the firearm their attached to, as long as it's not on there more than 30 days.;)
 
A M4gery would have been sold with a barrel on it, and the factory length will be in the system.
"how would they know if its a replacement barrel or your old cut barrel ?" Are you serious? Do you really think that a forensic examination would not discover whether a barrel had been altered or not?
Read the notification of change regulation carefully. There is nothing there that suggests that a change must still exist after 30 days, only that a change must be reported within thirty days.
Is it mandatory to report barrel length changes?
The information on a registration sheet refers to changes in classification, and changes to a receiver making it capable of discharging ammunition.
 
b ii) still gives the same barrel length of 457mm instead of the non-res 470mm

That's because that was the definition of a prohibited firearm. You can cut the barrel of manual action rifles down to 457mm and they maintain their NR status. The 470mm limit is only for semi autos being either restricted or NR.
