Since I know a lot of people get wrapped up in semantics, let me first say...
When I say "AR specific" I don't mean that only are to be used on an AR, but more that they are often used on ARs, or if a multi-purpose can one of the uses may be to install on an AR. Caliber is irrelevant in this case except to eliminate rimfire or pistol cans pressed into 300 BLK subsonic-only use, etc. We are talking here about centerfire rifle cans that might see use on a (typically, anyway) 5.56, 7.62, or 300 BLK AR15 pattern rifle.
The Silencerco "rumor" thread, along with all of the "I knew that was going to happen" replies, along with some folks opining as to what other folks should buy and other folks feeling the need to defend their purchase, has me wondering what the group's thoughts are on the current state of AR suppressors. There appear to be a whole bunch of new brands out there that I'm not familiar with, although several of them seem to involve people who may have had runs at other manufacturers previously.
So what's happening out there in the world of the AR suppressor? What's the new hotness? What's the old standby? What's the cutting edge? What's the bleeding edge? What's failing or proving to not be all it was hoped to be?
