I'm new to suppressors, although I now have 4. I was all in on sticking with direct thread, but have now changed my mind. I have two very similar rigs with 11.5" barrels. One is direct threaded and the other runs an SRX Mini brake. I do shoot A LOT. No less than 2k rounds of 5.56 a month. Just in the few thousand rounds I'm seeing noticeably more erosion on the blast baffle of the directed threaded can than I'm seeing on the can running the brake.
Honestly, if I wasn't so invested in SRX, I would have gone with the Plan B system using Atlas mounts. The muzzle device options are almost infinite and they are very reasonably priced.
