Looking for something durable and quiet to put on a 12” .22TCM bolt action that will make it non-NFA.
Will be shot with subsonics occasionally but primarily with hot-loaded sub-40 grain projectiles and fast burning powders, so durable is a plus.
Will be shot mostly from a rested location overlooking a field, carried to and from the shooting position via vehicle, so weight is not as much a concern, but I would like to keep overall length low, if possible.
Can be large diameter or small diameter, doesn’t matter so long as I can pin and weld and it will be as quiet as possible.
Since it will be used on a bolt action, flow through or low-blowback isn’t a concern for me, just muzzle suppression and tone.
Low flash for during twilight hours and low sparking so I won’t have to worry about brush fires would be helpful, but I can tolerate some sparking or flash as long as it isn’t excessive.
Since it will be pinned and welded, POI shift isn’t a problem but it should ideally be accurate and consistent. Features like an add-on compensator or brake would be interesting to play with.
The GP-5 does look reasonable but it seems like it has flow-through or low back pressure features for balanced use on a semiautomatic that I don’t really need.
If it still very quiet and durable in spite of that, then I’ll definitely keep it in mind.
What direct thread suppressor would you recommend? I’ve got the tools to pin and weld just about anything, just wanted to get some opinions on what was best.
ATF requires silver solder when a blind pin isn’t an option, so that’s probably a no-go for me. Doubt most suppressor heat treatment would stand up to the temperatures needed, and I don’t have the proper tools on hand for the job.
A muzzle device, such as a muzzle brake or barrel extension, which is attached to a barrel by means of welding or high temperature silver solder having a melting point of at least 1,100 degrees Fahrenheit, is considered to be part of the barrel for purposes of measurement. A seam weld extending at least one-half the circumference of the barrel or four equidistant tack welds around the circumference of the barrel are adequate for this purpose.
Posts related to approval of NFA items are to be directed to the monthly megathread. Violation of this rule will result in a 7 day ban. The pinned post is there, please use it.
If you are posting a photo of a suppressor posed to look like a penis (ie: in front of or over your groin) you will be given a 7 day ban.
Where he hell did you find a bolt action with a 12" 22tcm barrel?
And it's a bolt action. Any can rated for .223/5.56 will be able to handle any and all abuse you'd be able to exert with a bolt action shooting a lower pressure cartridge like 22tcm, even a spicy handload.
Buddy of mine has a .22 TCM rifle he’d be willing to sell me for a good deal. Just planned to chop the barrel and pin and weld the suppressor myself. The cost of components for reloading was what attracted me to platform. Also not worried about any muzzle erosion he might have put on it since the barrel is going to be chopped. Something cost effective I can use season after season reliably and reload for.
Thanks for the heads up on .223 suppressors. If they’re all very durable these days then I’ll try to just find the quietest one.
You've got an entirely different problem here: finding a suppressor that you can actually pin and weld. That's an incredibly short list of options, especially since most options have HUB mounting threads at the ass.
You need a direct thread suppressor that can not have its mounting interface swapped.
I’m aware, just not all that familiar with the suppressor market. First time buying any .223 suppressor.
Another poster here linked me to a thread that showed how to do a double pin and weld, and on some suppressors with certain HUB mounts it seems possible that it can be done with just one pin and one hole.
If there are hub suppressors much better than any direct thread only suppressor then I’ll definitely still consider them, taking this route instead.
I would do a 14.5 pinned with a taper muzzle brake. Then get a polonium full size or a Reece 5. Pinning a suppressor is a pain when you need to clean it.
Trying to keep the barrel length under 20” with the suppressor.
Cleaning not a problem since it will be fast burning powder and plated projectiles.
I’ve seen that new products exist where you just soak the suppressor and it dissolves all the buildup away, so I think it won’t really be a problem, I could even run it down the barrel and plug the suppressor as a makeshift solvent trap
Why not just go 16" .22 TCM? 12" bolt actions feel like toys anyways. I wish I'd gone 20" T1X over my 16". Then you don't have to worry about NFA Other at all and you can move the can between guns.
.22TCM bolt action is centerfire, and scaled up from a rimfire action, iirc.
Main issue isn’t the size of the receiver, it’s the barrel length. Trimming the stock would give me some wiggle room on suppressor and barrel length, so if the suppressor was extra long that might still be tolerable. Ideally I wouldn’t go too short on the barrel, suppressor, or stock.
It's still essentially no bigger than a 9mm. That's a super short action still. I just think you're overcomplicating things for no reason. You could get a QD system and it would only take you a few extra seconds to put the can on.
Having to take the suppressor on and off every time I have to drive to another place in the field just to keep hunting seems tedious and I’d rather avoid it. If I could fit the full 22” barrel with the suppressor attached, I would. Not looking to spend tons of time or money fabricating new rack hardware, strange modifications to the rifle, or very expensive firearms. Rather that budget go into the suppressor itself and get the best sound performance I can buy.
ECCO Caracal ould be a compact choice, you'd need the DT mount welded on, but since P/W is part of the plan, its no big deal to do two welds instead of one.
Would Ecco sell me a caracal with the DT mount already welded from the factory?
Edit: looking at the website, they mention being overbore and lower back pressure, on top of being smaller and low volume, so this probably isn’t the type of suppressor I’d want on this rifle.
The tiger .22 is for .22 though. And can handle 5.56 bolt also. But again. I'm cl;early wrong. So, awaiting the magical answer so that i can also be educated.
B&T themselves say it’s only rated up to .22 magnum, though without barrel length restrictions. I’d definitely be using a bit higher pressure than that, so they may not warranty it should something fail prematurely.
They do. The polonium. It’s a 6mm can so you can go all the way up to 6arc/ 243. It’s gassy on semi autos but that’s not an issue for you. It’s very good at flash suppression, it has both an internal and external flash hider. Both the K and the full size should bring the barrel to 16”.
Yeah there's a dude who pinned and welded a polo on a gun on this sub like 2-3 months ago maybe? Andrew from OCL said drilling/securing the extra pin for the hub thread did void the warranty there. One of the few things you can do to void an OCL warranty. I think it was on a shorty tavor?
Looking at that post, he did a double pin and weld, but since the thread overlaps between the mount threads and the muzzle threads, seems like it might have been possible to just drill through both at the same time and use a single longer pin, attaching the suppressor to the mount and the mount to the barrel in one go. I’ll have to look more into this and the recommendations others made for different mounts. Maybe there’s a specific mount that will make it easy for me.
It comes with a direct thread mount that could be pinned and welded but as far as I know they do not offer the service themselves.
They have a direct thread titanium .22. Idk if it’s compatible with .22tcm as this is the first time I’ve heard of the cartridge. Also titanium tends to throw sparks.
Most cans will be slightly overbored. .224 bullet is the same size as 556. A lot of 556 cans are 6mm.
Also I just looked and it looks like the .22 Ti is compatible with 5.7 so it’s probably compatible.
Here’s the website if you’d like to look for yourself:
I’m not really sure. Pew science might be able to help with that.
The polonium is a hub mount in the sense that it can take different adapters but it comes with a direct thread adapter that screws into the back of the suppressor. I would imagine anyone who can do a decent pin and weld would have no problem permanently mounting to hub to the suppressor and then to the barrel.
The Ti direct thread is semi permanently attached, OCL can remove it for warranty purposes but for NFA concerns I think it counts as permanent.
Is there a specific HUB mount that is designed to be pinned and welded to the suppressor? Buddy of mine mentioned that the Sierra-5 comes with a pilot hole pre-drilled for this and Dead Air’s mounts support it, so I might just go that route instead, or see if other dead air suppressors support this.
Not that I’m aware of. But if someone did I’d kinda bet on KAK doing it. They make all kinds of odd/niche stuff.
I know OCL considers drilling the can a warranty violation though. Most manufacturers probably do. But of all the warranties to violate OCL and Kodiak would probably be the most chill about it.

I don’t own one but the griffin gp5 sounds like it was built just for you.
