I have an array of suppressors from a PBS-4 for the AK to a AAC for the SCAR and they all change what folks at the receiving end hear and also do not affect accuracy. The AK one is particularly nice at this. There is also nice little Knights Armament Co SOCOM for a USP GBBB in the toolbox that works fine also.
These are all dry, anyone tested wet yet?
And as noted before, this is what the person in the To: line of the shot hears, not the Sender.
Airsoft, where nothing is hurt but feelings.
