I have an Omega that I use on a 12.5" Grendel. If I remember correctly SiCo rates the Omega on a 10.5" 223 barrel and 12.5" for most everything else. I haven't played with my set up in a while. I know I am over gased so it wasn't the quietest. It was definitly quieter than unsuppressed. Accuracy was about 1 moa with Hornady 129 sst at 100 yds.
