It's really been my go to can for anything under 6.5mm since I bought it way back in 2016, I've run it extensively on .260, 6.5CM, 5.56 18", 16", 14.5", 10.3" and now 6GT & it has done extremely well on all of them. I feel like it's performance for it's size/weight is still pretty damn impressive. I'm no expert but to my ear it's no louder than some full size 30 cal cans (Surefire & my old SAS stainless) & definitely quieter than any of the "K" size cans that I have heard in person. Sure it's probably old technology compared to some of the newer suppressors out there but honestly I haven't felt the need to look around for the "new hotness" since this can still works so well for me.
