Centerfire Can on Rimfire Rifle

[Denver_AR]

Thinking about running a centerfire can on rimfire rifle. What do I need to consider if going this route?
Should I run a direct thread and avoid anything that needs a brake? (Concerned with lead buildup in brake)
Any materials to use or avoid, like titanium vs stainless?
What's the cleaning process?

Rimfire ammo is really dirty and most centerfire cans can't be taken apart...

Figure out the cleaning process early.

Yea, unless the centerfire can is user serviceable (can be taken apart for cleaning) don’t use it for rimfire, unless you don’t care if you ruin the can. It’s incredible how much crap rimfire dumps in a suppressor. Just go buy a rimfire can, they’re relatively cheap and atf approval is prettyquick right now if buying as an individual.

I tried uploading a pic of a rimfire can innards before cleaning, but all file uploads failed for me. :(

I have shot tens of thousands of rounds of rimfire through Titanium centerfire cans. Despite what the internet sometimes says, the world didnt end and my cans did not get ruined.

When I am done shooting for the day I shake the junk out (mostly unburned powder and priming compound) and head home.

Every once in a while I will soak the can in CLR for a while, rinse it out a few times in the sink, and shoot a few rounds of centerfire through it the next range trip.

The cans used in my tests and normal shooting were/are Jet 30 caliber 9 inch, Sure Fire 212 and a Mini in 5.56, TBAC 7 inch Ultra series in 223, 6.5 and 30 caliber. The JET is a direct thread and the others all use brake adaptors.

That said, I do have several rimfire cans. They mainly get used on pistols and full auto machine guns with 22 conversions.

here is approximately 1500-2000 rounds on a specter2. There is a reason every suppressor manufacturer has a dedicated rimfire can.

SilencerCo HYBRID 46M with a direct thread 1/2x28 on many .22LR rifles and pistols with ZERO issues. Yeah it’s dirty but it don’t mean nothing.
Screw it on and enjoy.

Griffin Armament Optimus 9.
I use it on 9mm, 300 blk, 223 and 22 LR.
User serviceable or, for $150, send it to Griffin once a year and get it serviced and cleaned at the factory.

Like Hoser, I have thousands of rounds on a couple of Thunderbeast cans. I fill them with CLR whenever they start looking gunky. Problem solved. I absolutely don't understand the internet hysteria about it. My only guess is it's people who've never tried it themselves or perhaps don't know about CLR.

Does CLR interact ok with titanium? I have a Ti can that has had a crack repair done, and I?m just not super confident in it on a centerfire anymore. Would rather just devote it to a RF platform with a thread adapter than risk losing it entirely.

My understanding is CLR and titanium are compatible but CLR should not be used on stainless. Which is why TBAC recommends the 50/50 vinegar and peroxide mix on their TD22 since it has stainless baffles. The rest of their cans that are full titanium, use CLR. If I have that wrong feel free to correct me!

I just asked the CLR/Stainless question directly to Griffin Armament:
Message: Is it safe to use CLR to clean an Optimus 9 (tube, baffles, attachments, end caps, everything)?
If so should it be diluted or used pure?
Thank you.

Good Afternoon,
It is not. I have seen it destroy tubes. When using an ultrasonic cleaner on our user serviceable suppressors, we advise only putting unfinished components into the sonic cleaner. Things like the stainless steel baffles, piston, and spring can be put into sonic cleaners. The solution we typically use for this is Zep Heavy Duty Citrus Cleaner. Make sure not to use the sonic cleaner for finished components like the tube body, end caps, muzzle devices, mounting interfaces, etc. For cleaning the tube body, a round wire brush is a good option for cleaning.

Good info!

Shot about 200-250 rounds of Lapua rimfire ammo through my Thunderbeast 30 caliber Ultra 7 today. This was out of a 20 inch Vudoo 360.

Got home, took the can off and shook out the unburned powder. Took a peek in there with a borescope. The first baffle has a little crud on it, the rest looks like a normal 308 can inside.

I guess when it actually needs cleaning again I will soak it in CLR for an hour or so and rinse it out. But it has hardly gained any crud/weight in the past couple thousand rounds.

I guess I should have never shot all that 5.56 ammo through a 223 barrel either.

Yesterday I shot about 250 rounds of Eley Ten-X through my Thunderbeast 223 Centerfire Ultra 7 yesterday. This was out of a 25 inch barreled Vudoo single shot.

I shook out about 8.4 gns of unburned powder and other junk.

Just like normal the first baffle looks a little dirty, but all the other baffles look fine.

This can is over 6,000 rounds of pure lead and wax lube ammo put through it without cleaning. I dont remember the last time I shot a centerfire round through it actually.
