I am now getting on with silencing my vsr (tsd sd702). As of now, I have placed some foam in open spots in the stock, and made a foam filled silencer, which dampened the sound, but what else is there to do? I was considering putting mouse pad on the cylinder head. Realistically, how silent could I get? I have not seen any videos of how silent a sniper can get and I don't want to try to make it more silent than it is possible. On a side note, I am not looking to touch its spring or anything that would effect power.
