Hey brother,
Ive seen your setup on Silencertalk(fireman1291 here) nice rig.
To answer waterhouse, with wipes in place and 5cc-8cc gel or water it should last approx 20shots with FMJ 147grn ammo and sound like a bbgun. The wipes will be increasingly worn out shot after shot and the gun will get louder, until you change the wipes.
