Who here has a 9mm suppressor on their AR

cajunautoxer · Oct 29, 2014

So I think I'm gonna jump into the Class 3 pool. I was originally going to order a AAC Ti-rant but now leaning towards a Liberty. That way if I ever build a .300 I can use it for both rifles. Anyone care to give me some input. I'm a total Class 3 noob.

Also is there a ideal barrel length for 9mm AR? IIRC 11" is needed for 556 due to prevent baffle strikes. I plan to SBR it at the same time.

Mine had a 5" barrel on it.
Barrel length doesn't mean shite on blowback rifles in pistol calibers.

Really old crappy picture, but it's the only one I could find at the moment.

One of my customers just finished his 9mm SBR. He runs his YHM Cobra 9 on it under his handguard much like old Matt in the post above. Running 147gr Subsonics is SICK!! The choices for a good 9mm can are pretty open. The Octane, Ti-Rant, Tundra would all be good for this set up.

I would not run a 9mm pistol supressor on a rifle caliber (300BLK). Most are not designed for the increased pressure.

With the Liberty Mystic even though it's a pistol suppressor they day it's okay to shoot 300 as long as it's subsonic

The day will come when you want to use one on a 300 WInMag or a 30-30.
I would just be worried that I would slip up and put a standard velocity round in and have a really bad day at the range. Isn't the difference between subsonic and standard just a few grains of powder?

You mean just one can won't do? Sounds like a slippery slope this stamp thing

Sometimes I think being strung out on cocaine would be cheaper. But yes, the .22 suppressor is the gateway drug to the NFA stamp collecting.

The threads are different on 9mm barrels to rifle 223 barrels so you can't stuff up and put a 223supressor on a 9mm rifle unless you have had it threaded aftermarket
