Are AE/Ops Inc suppressors still a vaible design compared to more modern designs? I'm thinking of putting together a 11.5" SBR that'll be run fairly consistently with a can, and I'm really liking the AEM2 (Ops M4-M) design, as it only adds 2.5" of length past the muzzle device, and is reasonably light weight (under 15 oz). I know the attachment method is dated, and the bigger cans will suppress better, but I'm more worried about a good compromise between sound and size/weight, and less worried about absolute hearing safe operation. I've considered getting other designs too, Surefire, Silencerco, Griffin, Dead Air, etc. It seems like the AE/Ops cans are still pretty good to go, accepting their mounting limitations. Thoughts / opinions?
