What type flash hiders is everyone using for  9mm
5/1/2016 2:29:04 PM EDT
[#1]



Greetings,

Yankee Hill Machine that I picked up at a gun show. To be honest, at the time there didn't seem to be a large variety of MDs threaded for 9mm so can't say I did any comparative shopping or had a specific reason for picking that one. I've never shot my AR9mm in the dark, so can't comment on effectiveness. Good luck!

Regards, Jim

I use a regular A2 reamed out to pass the larger 9mm bullet.

This. I've got 2 or 3 of them, and they work well. Just be sure you don't screw a .223 flash hider on there by accident.
I use a steel number punch to put a "9" on my 9mm flash hiders. Or you could use a different type of hider. For example, use an A1 FH for 9mm, and an A2 for .223.

I'm currently using a KAK flash can on my 8.5" barrel and it's working fine.  I found a 9mm CMMG A2 for $13 on joebobs so I ordered it.  I haven't tried it out yet to see if it's much different though; it didn't come with a crush washer so I need to find a 9mm one somewhere before I can install it.

Well.... duh!  The A2's only there when I want to get loud - but when a man's asking about a flash suppressor, we're not supposed to tease him with our sound suppressor humble-brags, are we?

For y'all using the A2.  Does it provide any noticeable compensation with the 9mm?

No. But then neither does a regular compensator either.

You just have too little gas pressure / volume to work with.

In my humble opinion, a 9mm AR has absolutely no "need" for "compensation" of any kind.

Compensators do two things: cost money and make the muzzle blast do things the other folks on the range don't like.  Sometimes they also do a little more, like keep the muzzle down a bit more, but only when you have plenty of gas exiting the muzzle, which you won't with a 9mm.

I have an A2 on both of my 9mm uppers, I think.  (Maybe A1s?  I don't recall off the top of my head.) They protect the muzzle from my clumsiness.  Once I get a can in 9mm, that will change things.

I picked up a factory HK MP5 3 lug FH a long while back.  Can't see myself using it when I have an Octane 9.

I have a Vortex on mine.  I don't know if it does any good at all, since I never noticed any flash before it was installed.

I was thinking of going with a screw on 3-lug adapter for mine.  I doubt i'll ever be able to afford a suppressor, so it will just be for looks.

Thread protector ftw. Why waste money and add extra length and weight for something that's unnecessary?

I usually try to avoid buying gun parts off Amazon due to all the Chinese pot metal crap on there, but I figured it was worth a gamble at only $7.99 shipped Prime, because I didn't want a plain jane knurled one. It's perfect, I would highly recommend it. Made in USA, flawless machining, nice finish, correct threads (I bet the reviewer who said threads were wrong tried to put it on a 1/2-28), size is spot on.

Not a flash hider, but I use a TROS 3-Lug adapter.
