Thread: Quietest firearm possible?

There is a JP silent captured buffer spring available for Ar's to quieten the air-rifle like twang of buffer, supposed to be good but a little pricey if purchased here like everything else.
Troy Defense make a pump-action in 300AAC based largely on an Ar configuration with a folding stock, but NZ Police have made importers pin the folding stock. They look quite nicely made.
