So with the SLR and now MS Hitting the markets, I see there definitely being a need for proprietary (to maintain non-restricted status) .22lr chambered AR barrels as well as BCGs.

The only one I've seen so far is the CMMG bolt and barrel kits in various lengths. I know you carry some of their other conversions, so Is this something you will consider bringing in? I know of at least 2 people who are interested in a "Honey badger" .22lr NR clone.

Thanks!
 
I’ve said this in another thread for the MS, someone needs to check that the CMMG barrels are stamped 22LR or that the adapter collar is permanent on the barrel. The reason being is if there is any way to shoot 223 through that barrel and its under NR length you’ll be in possession of a non registered restricted rifle. I would ask CMMG before buying one of their kits to be sure.

I have a Spikes Bolt and barrel and the barrel collar and barrel are one solid machined part, marking it impossible to shoot 223 through it without heavy modification. It is an 11.5” barrel (just barely has a 26” OAL with a fixed carbine stock).
 
Gas port is irrelevant in this case, if the RCMP lab can fire one round that’s all they need (when classifying for FRT that’s the case anyways). I believe Shaun from ATRS was looking into it as well for the CMMG barrels. If anyone asks them please post the response on CGN!
 
Yes obviously but my point is if you are taking an AR barrel and adding a .22lr collar then there would be a gas port. As a machinist i can tell you that if I am making a barrel for a proprietary .22lr bolt and not cutting a gas port, I sure as hell ain't reaming out a chamber for .223....
Its possible, but I'm gonna say there is a next to 0 chance that you will be firing .223 out of that barrel without rechambering it.
 
I totally agree with you. But what I don’t understand is why the collar? From the pictures it’s separate from the barrel. My Spikes barrel is a single piece of metal, collar and all. That’s why I’d confirm. Could be cheaper to make 223 barrels with no port and slap an adapter in place then to machine proprietary 22LR barrels separately.
 
Can’t find the email but I asked cmmg if the 9” dedicated barrel was stamped .22lr and they said it is stamped or engraved .

Maybe it is just a barrel extension similar to how an AR has one. It's possible they did it in an effort to save machine time and material on the barrel, but hard to say. Either way my gut still tells me they should be good to go. But we'll have to see one first.

Thats good to go then, because it’s only designed for 22LR if it’s stamped.

What about those conversion bolts?
The ones where you pull out your 5.56 bolt, put in the .22lr bolt with the integrated chamber and drop in a new magazine and away you go.
That should still be plenty good.

Not if you want a short barrelled 22LR, since you’d be using a centerfire capable barrel.
 
I found the pictures they sent me of the 9” barrel if someone wants to post it I can email it just pm. It’s clearly engraved or stamped .22lr.

I use a cmmg 22 kit in my troy par sp I have no doubt it will work in the slr or ms

You mean a bolt kit or a barrel kit? Either way it remains NR because it’s a pump action, semis have centerfire barrel length restrictions that make the CMMG drop in kit only NR if it’s used with a +18.6” 223 barrel.

What we are after is dedicated 22LR uppers with barrels shorter then 18.6”, and from what Tungsten316 posted the CMMG barrels will work.

True.....but.....if the stock is fixed then..... ;)

Think Kel-tec KSG, Rossi ranch, etc.

You could be right, but it can fire without the stock (just needs a buffer tube). And those have a NR status because they leave the factory that way, I don’t know if building your own would work.

I’m not a dream killer, I just don’t want anyone breaking the law without realizing and jeopardizing our NR sets.

For sure, i couldnt afree more. I might have to machine some sort of setup myself. Maybe a non-collapsing version of NEAs ccs.....we'll see. Anyone have a 7.5" NEA15 they would be willing to measure up for me? Fully extended of course xD
 
So I could be wrong.....but according to the numbers I'm seeing it's 21 inches for a fully collapsed 7.5" AR with the ccs.
With the extra 1.5" on the barrel and fully extended CCS that comes to 26.25?? I have no issues tac welding a nub (pretty much permanent according to regs? Or would roll pins be Okay?) on each rod in order to prevent telescoping.
Thoughts?
