.22 LR and a .223 suppressor

[Expat]

I bought one of the CMMG .22 conversion kits for an AR. Thoughts on using my Surefire suppressor on it?

 

[daddyusmaximus]

It should work just fine, but it will get REAL dirty.

Most .22 cans come apart to clean. Well, mine does anyhow.

 

[Expat]

Will shooting the 5.56 rounds clean it out from the rimfire residue?

 

[daddyusmaximus]

Don't know, but that's a powerful blast.
My 5.56 uses a .30 cal can.

I bet @Aszerigan could answer your question

I don't recommend shooting a 22LR through anything but a rimfire dedicated suppressor. They get really dirty, and flecks of lead will come off the bullet during firing, and will gum up the inside of your suppressor. Surefire cans aren't meant to be taken down. You could soak them in a suppressor cleaner solution, but you're honestly better off getting a rimfire suppressor that you can scrub with a brush (i.e., Dead Air Mask 22, Silencerco Sparrow, Q Erector or El Camino, etc).

Not trying to sell another suppressor, but rimfire is it's own beast and needs it's own equipment. Shooting 556 through a centerfire suppressor caked with lead will probably make the problem far worse. It wouldn't clean it out. Shooting hot ammo through a dedicated centerfire can will clean it, since it blows all the powder residue out. But leading is another story.

Thanks Andrew.

You could get a user serviceable .556 can like a Griffin Paladin.

This is true, but it's overbuilt for a rimfire can, and much heavier than a standard 22 suppressor. Makes shooting it on a pistol unwieldy.

Yeah, I was more thinking of it being mainly on the AR that is being switched back and forth from .22 to .556.

I will say this with the Surefire Socoms that we have. I called my kid and told him that I cant get one of them off a Rock River after a few hundred rounds, and how do I get it off.
He laughed and said, Its Marine tough Pops, unlock it and shoot it off.
Well it went down range about 35-40' when I shot it, No harm done.
Money well spent each time.

I had to grunt a little taking it off after 120 rounds today. Plus, it was burning my little baby hands…

The AR that it ends up on, will be a dedicated .22 LR rifle. I have a BCM upper with a Surefire muzzle device, not currently being used. So it ran through my mind that I could use it for the 22 and use the surefire suppressor. Sounds like that is not such a good idea.

Most (if not all) 22 cans are direct thread. If you dont have that device pin/weld, I'd grab a 22LR can, and remove the muzzle device, then direct thread and let it live there on that upper.
Or grab the collar (if needed) for the CMMG kit and a dedicated 1:16 twist CMMG barrel and make a dedicated suppressed upper for it

No worries Baby Girl, no Judging from me.
My sister uses one of these and she also has a pair of carbon fiber mittens.
