Barrel Length for a Suppressed AR9

[GaMudd]

What buffer are you running? I'm looking to increase my buffer weight

I've got this barrel (TROS), and run JP Rifle SCS buffer. I like it, but I've never run anything other than that. It was widely recommended.

Mine is 7.5” and I shoot subs. It sounds fantastic.

Whose stock is that? Does it need a customer BCG?

Nah man it comes with 9mm buffer
It’s an MVB 9mm PDW ARC stock sits around 319ish

Yeah my AR9 is pretty loud suppressed. I havent gotten around to researching solutions yet, afraid those solutions might compromise reliability.

Mine is 4". 147's obviously stay subsonic at this length and it runs like a sewing machine suppressed (MPX)

I think 7.5" is a good length. I shoot 147gn handloads out of mine exclusively. Sounds fantastic. I can shoot it indoors comfortably.
