Claim 17:
18. An air gun that fires non-lethal projectiles for use with the magazine and pre-pack of claim 10, the air gun comprising:
the magazine and pre-pack of claim 10;
a barrel having a hop-up;
a receiver that defines a bore and a magazine well and includes a trigger group;
a bolt carrier group received within the bore, the bolt carrier group defining a gas inlet, a gas outlet, a pusher and a bolt that includes a rocket valve; and
a recoil buffer that is biased to push the bolt carrier group toward the barrel;
wherein actuating the trigger group releases gas out of the gas outlet;
wherein the rocket valve closes after a short delay, blocking gas flow into the barrel so that gas pressure pushes the bolt carrier group toward the buffer against the bias on the buffer; and
wherein the bias on the buffer pushed the bolt carrier group back toward the barrel.
