Anyone have any idea where to get a thread adapter to put a 9mm(1/2x28) Suppressor onto an ar15 300aac BO pistol (5/8x24)

OK Edit...

Went the wrong way...

Are you suggesting using both those adapters together?  Because either one will not do the trick.  That first adapter with change the threads of my  AR15 pistol from 5/8x24 to 1/2x24 then I would have to use the second adapter to reduce the overall size of the thread.  Theoretically that would do it but I am not sure how safe that would be plus the fact that you would have a silencer screwed onto and adapter screwed onto another adapter screwed onto the barrel.  I am looking for a single thread adapter.

Edit... Thats what you meant when you said wrong way...

Actually that first thread adapter would do the exact opposite of what I needed.  I have thoroughly searched all sites I could think of to find the right adapter silencer shop, silencer store, ebay, amazon, ect... None of them have the correct adapter to do what I need

My FFL, who has a great deal of knowledge concerning suppressors, said using a pistol can for a rifle cartridge is not a good idea. The rifle cartridge will produce more pressure than a pistol cartridge. In the case of newer osprey models, the pieces that are press fit together will begin to separate.

Yeah the second one was to illustrate what you need.  Will say though that if you got that one and had the female end tapped to the 5/8 size you'd be in business.  

I agree, however, that a rifle cartridge is going to put excess wear on your pistol internals.  If you running Ti that changes things a bit, but otherwise I couldn't recommend doing it either.

Actually this was a TI-Rant 9s so I Heard that it would do pretty well with 300 AAC BO

That's an odd size for a 9mm barrel.  The reason they don't put 1/2x28 on 9mm barrels is the danger of screwing on a 5.55 flash suppressor and having a kaboom.  That being said, that's a weird thread pattern for a 9mm can obviously because it's odd to see that on a 9mm barrel.  

TROS USA makes about every adapter possible.  But I don't think they would make that one, because it's such a weird combo.  Not all of their adapters are listed on their website.  You'll have to call them.

9mm cans work fine for BO subsonic.  You wouldn't want to put full power loads through it though.

300 Blk subsonic isn't really a "rifle" round.  

Here's one source that measured the pressure.

He's asking for something that doesn't exist because no one makes a 9mm barrel in 1/2x28 (it's irrelevant what his barrel actually is because to get to what he wants, the first thing has to exist).  He has a 9mm suppressor for a barrel that doesn't exist.  Do you understand that's why what he's looking for doesn't exist?  Are you paying attention?  

TROS will make him one.  That's all he needs to know, Mr. Peanut Gallery.  If you think you've got the answer, state it or STFU.

Dude! Did you leave your account logged in? Somebody is posing as you and pranking people!!!!!!!!!!


Seriously. Do you have any idea what you're going on about? Several people make 9mm barrels in 1/2x28. I have one from CMMG.

BTW, I run my 9mm can with a 1/2x28 fixed mount on my 4.5" AR 9mm upper.

ETA. I run my 9mm can on 300BLK with a 5/8x24 fixed mount.

Yes, I know they exist.  Storm Lake makes Glock barrels with 1/2"x28 threads.  It's all very dangerous because you can screw on a 5.56 flash hider on there and blow up your gun.  That's why most responsible manufacturers use 1/2"x36 on their 9mm barrels.  Not a big deal until you do it.  

But you're still not going to find that adapter because responsible manufacturers are not stupid enough to take a .308 thread and reduce it to 5.56 because you really don't want to put a 5.56 flash hider on a .308.

That's still the point, YOU WILL NOT FIND ONE because it's not a good idea from a manufacturing liability stand point.  That being said, you can have anything made.

Guess they weren't stupid enough to put 1/2-28" on an AR-15 barrel (although that really doesn't mean they aren't that stupid, ya know).  

https://www.cmmginc.com/shop/barrel-sub-assm-8-5-mt-4140cm-sbn-9mm/

By the way, now that you get it, good luck finding that adapter (advertised) which is still the original request.  It's not going to happen because it's not a good idea to make one.  I wouldn't turn one of those unless I really trusted the person.  It's OK to own one, though.  9mm cans work well on subsonic Blackout.

Actually you cannot put a 5.56 flash hider on a 9mm Barrel... Even if the thread pitch is the same (1/2x28) the barrel diameter is different so that really doesn't apply...Thread pitch doesn't not equal barrel size at all... 1/2x28 is a very common thread for many 9mm barrels.  Why else would that be the default threading on those silencers?

Uhhhhhh the 1/2 in 1/2x28 is the diameter ...

Also if you will look at the link you have,,, the barrel narrows to the diameter of a normal 9mm pistol barrel...There is no way a normal 5.56 flash hider will attach to that even if the threads were both 1/2x28 for the barrel and the flash hider...that is done by design

Well its more complicated than that but the point is the 1/2" is not the diameter of the barrel

It's the diameter of the threaded portion of the barrel. Saying one 1/2x28 flash hider won't fit on some barrels threaded 1/2x28 is complete nonsense

1/2", 9/16", 5/8" are the barrel diameters at the threaded area of the muzzle. Not the length of the threaded section of muzzle.

So you are saying that my 5.56(1/2x28) flash hider will screw onto my glock 9mm threaded barrel(1/2x28) ???

I stand corrected...I never removed a flash hider from one of my ar15s before a looked...I always saw the outside of the barrel and believed that it was about that diameter but since I just tried and succeeded then  that does seem a bit odd... From what I have seen the 1/2x28 is one of the most common thread pitches for 9mm silencers and 9mm barrels and for that to be the same threading for 5.56 seems unwise
