Application / Regulation advice Rim fire over all length question.

When it comes to legal OAL for a rim fire fire arm is the muzzle attachment included? For example if i wanted to put a folding stock on my rifle that would bring it under legal length if I attached a fake suppressor and just never removed it would it still count towards the overall length even though it could be removed with out a tool?

the barrel length is the distance from the muzzle of the barrel to and including the chamber.

This only applies to centerfire rifles, rimfire does not have barrel length minimums.

Rimfires just need to be 660mm long minimum not to be classified as a restricted firearm.

Permanently attached muzzle devices should count towards overall length, which is the only metric that matters for a rimfire. It's really no different than a removable picatinny stock.

As for the folding stock, if your gun can fire while folded, it won't meet the minimum length definitions, so I avoided getting a folding stock for my 10/22. It's too bad there aren't more fixed picatinny stocks on the market though, lots of cheap folding ones.

You know what, you are absolutely right. I ended up going down a bit of a rabbit hole focusing on the barrel length.

I can’t find anywhere on either the RCMP website or firearms program where they mention any legal way of measuring the OAL.

In my mind though if an attachment to the barrel does not count towards its length for legal measurements, I can’t see how it would count towards the overall length of the firearm for a legal measurement either.

Yeah, there’s nothing defined for rimfires, so it’s up for interpretation.

As for permanently attaching muzzle devices, anyone know where to get Rocksett in Canada? Similarly Vibra-Tite VC-3? It seems like we have a shortage of these threadlockers.

Is there a defined way for centre fire when it comes to measuring overall length?

I can’t even find anything for them outside of needing an 18.6” barrel and above 26” OAL.

If rockset isn’t an option, I’m sure a pin and weld would be just as solid. 🤷🏽‍♂️
