Your going to have to cut it and turn new threads to be concentric.

If you wanted to be dumb and make work for yourself you could scheme up an adapter to get you 5/8x24 threads after the muzzle, but it would have nothing to index from, and almost certainly nothing concentric to the bore, so I wouldn't personally bother.

Then again, I would probably suggest to hear an AK suppressed before doing anything. Likely you'll change your mind about the entire project and end up with an AR in 300blk.

I would be downloading the powder charge to go subsonic. Dies are available for 5.45x39.  


I think I found a solution, red jacket makes a QD muzzle device for 14/1LH threads this has, and it looks like it would work, they also make a can they will put the 14/1LH threads on as an option, or will work with the QD.

Considering the cost of reloading .300 AAC compared to down charging the load on Russian steel cases, the cost won't be comparable.


this will thread on the threads and the barrel will fit inside the FH and then this will attach to that device, or I could have it threaded right on. Other than being expose to carbon, I don't see how it could be harmed by having the barrel protrude into the can a bit past the threads...

Quoted:


Lol, not a single aspect of your problems has to do with cost. I suggest you research the hundreds of posters asking about suppressed AKs over the years that either gave up or are disappointed in the result. In fact, I don't don't think I've ever seen anyone suppress and AK then recommend someone else do the same.

Good luck.

I love suppressor projects, and Ive done about everything, but AK's are junk to suppress and leave lots to be desired.  Its your money.

Quoted:


Why?

It's a piston gun, so no gas in your face. What makes them junk to suppress? I don't see the difference as long as you have subsonic ammo?

Quoted:


red jacket does em all the time

Lol wut? Um, are you trying to prove my point?



To the other poster, AKs suck because they have extremely loose tolerances, are way overgassed, and vent out into the air right in front of you during peak pressure. All things that make it work in snow/-20deg to mud/140deg, make it shitty to suppress. This isn't even sort of uncommon knowledge.

Quoted:


Loud sloppy action and barrels and threads that usually dont lend well to suppressor mounting.  Why do you want to try to run subsonic 5.45?  You think that will cycle?  Get a 22lr if thats all your going to do.

I don't know much about suppressed weapons, trying to learn. AS long as i could get it to cycle with subsonic ammo, and it was relatively quiet, that works for me. I don't care about mechanical sounds, just don't want the blast so I can hunt and shoot without hearing protection on. Hunting hogs with suppressors at night is legal in Texas.

Quoted:



There is nothing wrong with trying, and everything should be suppressed, but some platforms are uphill battles with marginal (at best) returns for your troubles and money.  Something with an adjuable gas system, be it piston or DI, would simply get you quiet enough, cheap enough(sorta), to say it was worth it.  The quest to be different is hard to get past though.

Quoted:


I suppose what I don't understand is why should 5.45 be harder to suppress than .223? They are quite similar in many characteristics. So the AKs have leaky gas, but other than than  comfort for the shooter, why is that a problem? Just trying to understand the specific problems I would have to overcome with this platform.

It's a very poor choice to buy a can specifically for as it doesn't work particularly well.

In addition, you WILL need to get it brought to a gunsmith, if nothing else other than to check the concentricness of your threads. There's no way around or way to cheat your AKs threads not being concentric to the bore. If they're not, you'll have baffle and endcap strikes and end up wrecking your can. This isn't a little deal, and its very important that the theads are proper so you don't shoot a hole in your can and shoot it down the 10 yard line at the range.

Quoted:
OK so the consensus is that it is impossible to successfully suppress an AK74? Bonehead idea I guess.

Quoted:


It's not the WORST idea out there, however...

AKs suck to suppress and you want to stick an oil filter on the end of your barrel and call it a day. You're basically stacking one cheap half-assed option on another and hoping it works.

As for your buddy who shoots hogs with .223 subs... well frankly that's a dick moving knowing you need to put a few into them. It's one thing to botch a shot while attempting a clean kill, it's another to go into it knowing you're gonna have to shoot your prey a few times to end it's misery.

Quoted:


Well they drop faster with subsonic 5.56mm than they do with bow shots. Does that mean bow hunters are all dicks... the small hogs are the only ones worth eating, the older ones have very strong tasting meat.
Doesn't take a huge round to drop a young feral with good placement.

I had a guy in Conroe process 2 bores and 2 sows that I shot in February into link sausage.......delicious.  Unprocessed though, yes, is kinda strong and needs lots of seasoning.

Ha, now we're talking subsonic AK?

First off, the AK is overgassed, but only 20-40% of that actually runs the action. The rest is "blow by", to examine this, look at the rings turned into the AK's piston, these are there to create surface tension on the gasses flowing by. In order to get subsonic ammo to reliably run, you would likely need a very very fast powder, a long time, and most likely you would need to either increase tolerances of the parts to increase the amount of action-effective gas or just open the gas port even more than it already is..... And for what? How heavy a projectile do you think your AK twist can stabilize? Because anything under 147gr IMO is pointless subsonic, might as well launch a 9mm or a 22lr considering cost and effectiveness. At 220gr the 300blk is so amazingly superior to all this hassle that again, I can't imagine anyone being foolish enough to bother with it.

The AK suppressed will NEVER be hearing safe. The noise of the action alone I'm sure is above 140db at the ear. The AR subsonic is sort of pushing it when metered at the shooters ear (shhhh, dark secret). Add in the blast from the gasses at the port venting to atmosphere, it's a non-starter. Poster above is correct that the only people that suppress the AK are the WhyNots, that already have a good host gun with easy to thread/attach specs and a can they use more appropriately on other guns.

That's great you want to shoot hogs. But the best hand loaded Ak subsonic just ballisticly fails so hard next to your run of the mill 300blk. Like I said posts and posts ago. Even if you could get it to run it's a waste of time.

The suppressed AK is not a first timers project and most people in the know wouldn't bother given free time and the means to make it happen.

Quoted:


I highly recommend it. Very effective, and I'm not disappointed at all. In fact, I was rather pleased because all my reading on here left me with low expectations

7,62x39 AK can stabilise at least 200gr bullet, maybe heavier. I don't think there is much use in trying to go heavier though. Gun cycles just fine, and mine has a factory gas cut-off valve to make it absolutely quiet. Not that the action is so loud that it'd matter, but it is a nice feature to have. I agree suppressing a 5,45 makes about as much sense as suppressing a 5,56, since both of them depend on the speed to be effective. But, and this is big but, 7,62 is one of the most versatile cartridges out there and is an excellent round to be loaded as subsonic.

What comes to suppressing AK's and "whynots": Russian army has suppressed AK's for decades. They have found it extremely useful hand have since expanded on the idea with a family of silenced weapons and cartridges.

Hassle of suppressing an AK in my case consisted on buying a can and screwing it on the flash hider.

What can did you use and how did you mount it?

Quoted:



The problem is long term cost for .300 BLK would severely inhibit my shooting time - cost wise and availability wise. Even during the great ammo panic of 2013, I have been able to find cases of 5.45 for less than $0.23 a round. Try doing that with .300 BLK. I would pay that jus for the .30 cal FMJ bullet needed to reload a .300 BLK cartridge. I could convert one of may ARs to .300 BLK with just a barrel replacement, I rebarrel my own, but it's the cost availability of the ammo I find daunting. Even 5.56 is easily twice the price of what I am buy 5.45 for right now. With this system, basically I could pay my $200 tax stamp, $300 for the NFA trust, and the rest is peanuts. With the adapter piece serialized, the filters become a maintenance component. Heavy, unwieldy, sure, but my goal isn't CQB here.  

My other idea was a suppressed AR15 .45 ACP upper, using the same adapter system, but I have not been able to find a .45 ACP upper in stock, and I don't know how blowback fares vs piston for suppression.
