I own or have owned multiple 16", 18", and 20" large frame ARs in 308 & 260. All are run suppressed. No two ways about it, the 16" is the one I grab the most. The others aren't even close. With a can they get stupid long and the 16" is the sweet spot. I fought this for years and built 18" & 20" guns because I was concerned about velocity. Eventually I landed on the 16" just like a shooting buddy who had already been through the same experience said I would.
