AR-9 and Silencerco Hybrid

[futureagg]

If I want to shoot an AR-9 with an 8” barrel or a 16” barrel. Do I need to add the spring piston? Or no? Thanks

You need the piston but remove the spring and replace it with a fixed barrel spacer.

Do you happen to have a picture of the set up by chance?

Here's what he is talking about. https://silencerco.com/fixed-barrel-spacer.html

However, you can just use an endcap that matches your barrel thread. A piston setup is only needed for guns without a fixed barrel, i.e. most pistols.

This is true as well.

Gotcha, so I currently have the can set up with the ASR mount, so if I found an ASR brake in the same thread pitch as the upper I can just use that and I don’t have to worry about the piston?

That is correct.

Whoa hold on right there. I’m assuming with an AR9 you’re shooting a 9mm or .355 projectile. You’ll find plenty of 1/2-28 ASR brakes and flash hiders, but I don’t know of a single one that will support a .355 projectile. Most, if not all, of the 1/2-28 ASR mounts are for 223/556.

That is correct. Or even 30cal in 5.8x24. But I am not sure if silencerco even makes a brake for it or not. Haven’t checked yet. Because aren’t most threads on AR9 1/2x36?

Whoa, totally missed that. [emoji2361]

They make flash hiders in 9mm, I got one for my cz scorpion from here

For the brakes you'd need to bump up to a 5/8" thread with a .46" bore, but ive also got one of those on my 45-70 (mine is 11/16" thread). here https://www.capitolarmory.com/silenc...zle-brake.html

they also make one in 1/2"-36 for 9mm if you've got odd threads like that

Yes sir I see that in the post above now. Good to know. Thanks

First thing I did with my AR9 was yank the barrel and send it to Morgan at Class 3 Machining to be rethreaded to 5/8-24. My 9MM can had that thread.
