The interpretation by the SFSS guys regarding short barrels in 22 LR on our MV and MS.

Good afternoon Rick,

Your question has been referred to me. I understand the specific question to be the classification of a rifle with a 22 Long Rifle (rimfire) barrel mounted on the receiver of a semiautomatic centre fire rifle (the Modern Sporter), temporarily replacing the centre fire barrel. You also mention that the overall length will never be less than 660 mm (26 inches) on folding of telescoping stock models.

Given the above, the provisions which render a rifle a restricted firearm via a folding or telescoping stock, would not apply.

Thus the determining factor, and the precise point of your question, would be whether the 470 mm barrel length provision applies. In this case, I believe it does.

The description of the firearm clearly establishes that it is not a prohibited firearm, but also establishes the underlying firearm is capable of discharging centrefire ammunition in a semiautomatic manner, even though that is not what is intended when the 22LR barrel is installed.

The remaining factor is the length of the barrel, which would result in a restricted firearm classification if the barrel length were less than 470 mm; and with a longer barrel, non-restricted.

So if a non-restricted outcome is desired, the barrel length of the 22LR barrel must be over 470 mm (18.5 inches).

So they don’t understand he laws they enforce? Since we’d have 2 or more uppers and centerfire barrels would be 18.6” or longer and the other would be 22LR at a 26” OAL. I don’t want to go to court to find out what our justice system thinks but Murray Smith is wrong according to the law. His BS about it being temporary doesn’t makes sense since both options are NR by themselves, you can’t mix centerfire rifle barrel laws into rimfire rifles. I can’t see how but if any of you know why I could be wrong please let me know.

Edit: I see a lot was posted as I typed this (or I missed posts looking at timestamps), but as someone pointed out, the 22LR Barrel isn’t capable of firing centerfire ammunition, no matter the markings of the lower or the intended design. If you mark the lowers Multi-Cal in the future would that appease them?

I think the problem is the classified portion was classified as centre fire multi caliber. Therefore whatever caliber even rimfire then falls under centrefire barrel laws. It doesn’t make sense but you aren’t going to win this argument on the side of a mountain and because our laws are written to be individually interpreted you may not win in court. I have an ar-22 that I was going to strip for my SS upper but now I’m just going to buy a conversion kit and use the 20” barrel I have on my SLR for a rimfire upper.

The question would be then using their logic, would you be limited to 5 rd mags? If it is supposed to play by centrefire rules due to the receiver and the rimfire barrel must be a certain length, then would rimfire mags have to be limited as well? Maybe some questions are better left unasked, lol.

What I’m saying is when you read the laws the classes are; non-restricted, restricted, and prohibited. If the firearm is not restricted or prohibited by the parameters set out in the law then it’s non-restricted. In this case there is nothing about a short barrelled 22LR upper that would restrict this firearm if you have 26” OAL. I know we won’t win the argument, but they essentially made up the part you pointed out, since it’s not in the law. Unless I missed the part where non-restricted have sub classes for cartridge type, it’s BS.

If I have a 22LR rifle and make it capable of firing 223 then I can have a barrel under 18.6”? Not a chance, then why would it work the other way?

Do it, do it, do it! It's not even in the FRT. And the FRT isn't even law; if it was there would need to be public access to it.

Lucky I fat-fingered my (grey market) order for the JP last night. I just put in for a 20" cmmg barrel/bolt instead

What is not clear in Mr. Murrays interpretation is what configuration he envisioned:

1- some manufacturers supply just a complete BCG with an extended chamber insert which allows the user to shoot 22LR ammo out of a 223 barrel (such as the original Colt 22LR conversion kits). In this case, the barrel remains a centerfire... I can better understand his "I believe"

2- In the case of other manufacturers such as A2 Armament, Tactical Solutions and others, they supply a rimfire specific barrel and BCG which are totally incompatible with centerfire. I such a case, I challenge Mr. Murrays "I believe"...

Perhaps Rick could clarify his initial query to him... to see if there remains an opportunity for a short barrel dedicated 22... food for thought !
