It'll definitely sound good at ear if your host weapon isn't massively overgassed. Muzzle report will be similar to a Sandman-S.
If you put a tighter front cap on it (like a 7.62 cap) it'll really sound amazing on an AR. I'm not a fan of super tight front caps on long cans, so that's where I recommend that for your AR in 5.56 up to even up to 7.62 cartridges (if you check with an alignment rod on the latter). The bonus is that you'll really enjoy it on the chunky subsonic rounds if you go that route.
It also has a very thick blast baffle and blast chamber, so if you decide to put some abuse on it (say, you're getting overrun by trash pandas) then you can definitely lay waste. I would still choose a Sandman if you do a lot of carbine courses and/or mag dump into trash on a common basis.
I hope that quick take helps!
