I am wondering how hard it would be to get the barrel shortened on a MR223. Is there anyone here who has had it done or knows who could do the work? Or even knows of someone who has had it done. Any information would be very helpful, thank you.
Illegal, AR barrels must be of new manufacture and cannot be shortened in any way.
Can you just buy an S&J 10 incher and go through a regular AR-15 installation process? I somehow doubt it, but I'm sure there's a way.
This is wrong, AR barrels are no different than any other rifle barrel. Any barrel can be shortened, but only to 18", as noted by Caleb314. If the original barrel is shorter than 18" it cannot be shortened and must be replaced with a new manufacture short barrel.

Which as you already know is then creating a prohibited device. We have had this discussion before. You are NOT legally allowed to cut down the barrel on an AR15 style firearm. I don't like that bit of law either but to encourage someone into breaking the law??????
Which is what I thought. For some reason Alberta Tactical Rifle is saying you cannot cut an AR barrel at all...they stated this in the PDW thread. I asked them to clarify they have ignored my post. I figure that is where the confusion is coming from.

(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
This is mostly true, however things get very ambiguous when referring to AR-15 pistols (which are recognized by the RCMP).

The CC reads:
It mentions a firearm that is adapted from a rifle or a shotgun. Not a pistol....
