6arc Silencer recommendations

I'm looking for a can for a 6arc bolt gun, so 6mm - 308 bore. Diligent Defense has 9.3oz and 10.5oz models. Otter Creek has 11.9oz and 9.5oz. What else should I look at?
Otter Creek Labs Hydrogen-S 6.5mm… It’s what I run on mine. Really quiet, and just as accurate on my rifles as my TBAC cans.

Black Ankle actually has one in stock…Only one I could find on the net. Snag it before it’s too late. 👍🏼
