So the PS90 comes with a 16" barrel and is restricted. If you were to put a muzzle device on it to bring the barrel over 18.5" is it then considered non restricted and can you unregister it?
 
Pinning/welding a muzzle device on a barrel doesn't count towards barrel length in Canada. Nor does it count if its integrally machined.

Barrel length has to do with where your lands/grooves end.
 
Wrong, the muzzle device counts if its machined into the barrel.

If it is machined where there are still lands/grooves, yes.
IE: Ported Glock barrels

If the muzzle device is machined, part of the barrel, but after the lands/grooves, it doesn't count.
A few companies tried importing AR barrels with an integrated muzzle device. Barrel would be 18.6", but 2" of that was the muzzle device (give or take). Because the way they were machined, it wouldn't pass our beloved RCMP.

You are 100% wrong and should really stop embarrassing yourself. Barrel length has absolutely nothing to do with the length of the rifling, there is zero mention of that in any of the laws. Barrel length is the distance from the breech face to the muzzle, and is the measurement of continuous material between them. If you have a barrel that’s 20” long, and for some reason you decided to counterbore out 10” of the rifling, the barrel is still 20” long. If you welded two 10” bars end to end, then made a barrel out of it, technically the barrel would be 10” long (though nobody would ever know or bother checking that). If you had a 10” barrel, and permanently affixed a 10” extension, the barrel would only legally count as 10”.

Your assertion that some 18.6” AR barrels were blocked from import because of an integrated muzzle device is ridiculous. I don’t necessarily doubt that the idiots at CBSA did that didn’t permit them, but it certainly has nothing to do with the law.

As for OP, no, you cannot in any way extend the legal barrel length by adding material to it. Theoretically you could stretch the barrel to the desired length, but that would have all sorts of unfortunate consequences, and may not even be physically possible before the barrel material fails, or the bore constricts to a dangerous point. Your only viable solution is to have a new, longer barrel installed, with or without an integrated muzzle device.

"Criminal Code section 84:

Barrel length

(2) For the purposes of this Part, the length of a barrel of a firearm is

(a) in the case of a revolver, the distance from the muzzle of the barrel to the breach end immediately in front of the cylinder, and

(b) in any other case, the distance from the muzzle of the barrel to and including the chamber,

but does not include the length of any component, part or accessory including any component, part or accessory designed or intended to suppress the muzzle flash or reduce recoil."


Porting a barrel is different then attaching a muzzle device.

You could port a 18.6" barrel and be fine, but indexing a muzzle device on a shorter barrel to make it 18.6" DOES NOT count towards the barrel length.

A machined flash suppressor on a barrel is not a component or an accessory.
 
If it is a continuation of the rifling.

There is no mention of rifling being a requirement for barrel length so I have no idea where you got your information from but it is wrong. If a barrel has a muzzle brake, or a flash hider, or anything else machined onto the end of it and it is one continuous part of the barrel then it is counted as barrel length. There have been plenty of gunsmiths who have made non-restricted 18.6" barrels with flash hiders for all kinds of semi-autos.

Your reading comprehension is terrible and you’re not even consistent in your argument. Nobody said that adding a muzzle brake is acceptable. But machining a muzzle device directly into the barrel steel is 100% permitted and absolutely “contributes” (or at least not detract) from barrel length.
 
The 16" model if you count the "muzzle device" is already around 18.6. What you see on the rifle is a outer shroud with a 16" inner barrel (used to determine classification). The cool thing with the ps90 barrel conversion is it just fills the stock barrel shroud, with the new barrel "filling" the stock muzzle device and ending flush to the end. So at least it doesn't look more stupid than it already does, just looks exactly the same.

Ok now apply this logic to smoothbore shotguns.

This. Seriously...

People misinterpreting and adding to the law, then passing that off as the actual law is why most people have a distorted view on what is or isn't legal.

There is NOTHING in the firearms act about rifling being required to count as barrel length. A very deep recessed target crown on a barrel does not decrease the barrel length by that depth amount.
 
Quite simply, look to the Swiss Arms firearms for your answer. The full size rifles and the both the short barrel and long barrel carbines have integral flash suppressors. If you measure these barrels, the integral flash hiders are counted toward the length.

I converted the first Swiss Arms Carbine to non-res, buy contracting Herron Arms to design and build an 18.6” barrel WITH an integrated flash suppressor. Barrel length was measured from bolt face on a closed bolt, to the end of the muzzle.
 
Herron arms has been doing 18.6" barrels with integral muzzle devices for years. If a major gunsmith is willing to do that, they WILL have a letter from the RCMP tech branch stating it is legal to do so. Nobody is going to risk a business venture over 2" and an ounce of weight.

It has been stated by the RCMP that permanently attaching a muzzle device to a barrel does NOT count towards barrel length, however as long as the barrel is continuously manufactured it doesn't matter where the lands/grooves or crown is.

There is a ton of stuff that doesn't make sense in the firearms act, it's been admitted by RCMP brass it was written that way ON PURPOSE. The only way to be protected from the law is to have a letter addressed to you from the RCMP tech branch stating what you want to know.

Also, as another confirmation to this, the Swiss Arms rifles are an example of this. The flash hider is machined into the barrel, the actual "rifled/chamber" component of the barrel is only 18-19" but it's listed on the FRT as a 20" barrel.
