OSS HX-QD 5.56. I had a SilencerCo Specwar 5.56 on here previously and it was quieter. Left hand shooters complained about gas in the face though. I figured with ear plugs in anyway, I’d get this OSS can and put the quieter, more back pressure Specwar 5.56 on my Bergara B14 HMR 22-250 bolt action. It performs fantastic on there.
