The Flow is the quietest can at shooters ear that Pew Science has tested and it’s also a K can configuration which is nuts.Do a little reading over on snipers hide. After doing a fair bit of research, I came to the conclusion that flow through cans are considerably louder than the alternative, but of course you have to deal with the gas somehow.
Actually it makes sense on an AR style gun. The best cans are not quite hearing safe at the shooters ear. If the can is quiet at the muzzle it will push gas back to the bolt and noise level at the shooters ear ends up higher. Data from the suppressor summit shows this. Muzzle might be 20 db lower on a really quiet can. A noisy can may be loud at the muzzle and be quieter at the shooters ear. The gas just goes out the front instead of the bolt. This is why AR’s are not as quiet as fixed breach guns.The Flow is the quietest can at shooters ear that Pew Science has tested and it’s also a K can configuration which is nuts.
I'd take a look at the flow 7.62. It's not cheap but actually scored pretty well for reduction on a 308 bolt gun. I think CGS makes a can people like a lot, too.Yea, I was told they are louder to people standing around you, but good for the shooter, due to the blast going forward. But I hate to spend that much and not have quiet, and Im looking for something for all my guns (as a first time can owner). but seems you can have quiet or no gas, take your pick.
