I have the Silencer Omega 30 cal. I have messed it up trying to load my own sub sonics . Sent in to get fixed, they repaired it at no cost, could not believe it. Best customer service you can ask for. Plus their brake/ adapter system let's me move it to my 223 22lr. 243 etc. very quickly, the finned end cap also gives you a cooler place to grab without an expensive cover when moving from one gun to another.
