Looking at the 30p-1 and the 30cb9. I'm trying to determine if I want a direct thread on or one with the brake. I'm looking for a suppressor to run on my 308, 6.5cm and ar. So it will see a number of rounds a year. I know it says almost indefinite if used accordingly, but is also says that with the brake it will help them last longer. Just trying to find out if 10k rounds would be possible or more.
