I clean at shorter intervals when shooting suppressed anyway. So cleaning a brake when I'm already cleaning a rifle+can isn't a bother at all. Its the easiest part of that process. What does bother me is having a can with a habit of loosening on me. YMMV, but ive seen them loosen upx especially on skinnier contoured barrels which is why my opinion is the way it is.
Why do you feel DT cans are the only way to go? Are there other CONs to running a brake-mount I'm not thinking of? The only one that comes to mind is a little extra weight in some cases. Do you lose a baffle/suppression compared to the DT?
I'm not trying to prove that brake-mounts are superior lol. I'm just curious why you specifically prefer DT.
