Non-lethal gas operated gun

1. A pre-pack assembly for use with an air gun, wherein the pre-pack assembly is removably insertable into a magazine that is removably insertable into the air gun, the pre-pack assembly comprising:

a pre-pack that contains a gas canister, wherein inserting the pre-pack into a chamber of the magazine fluidly connects the gas canister with the magazine, wherein the pre-pack comprises a first casing housing and a second casing housing that together define a compartment that secures the gas canister.

2. The pre-pack assembly of claim 1 , wherein the first casing housing and the second casing housing together define a cradle portion that secures a nozzle of the gas canister.

3. The pre-pack assembly of claim 1 , wherein the first casing housing and the second casing housing together define a compartment large enough to contain a plurality of non-lethal projectiles.

4. The pre-pack assembly of claim 3 , wherein the pre-pack comprises a feeder portion and the magazine defines an opening that the feeder portion extends through when the pre-pack is inserted into the magazine.

5. The pre-pack assembly of claim 4 , wherein the pre-pack comprises a follower and a biasing member adapted to bias non-lethal projectiles in the compartment toward the feeder portion.

6. The pre-pack assembly of claim 3 , wherein the compartment is large enough to contain at least 30 non-lethal projectiles.

7. The pre-pack assembly of claim 1 , wherein the gas canister is adhered to the first casing housing.

8. A magazine assembly for use with the pre-pack assembly and the air gun of claim 1 , the magazine comprising:

the pre-pack assembly of claim 1 ;

a magazine enclosure assembly that defines a chamber that receives the pre-pack assembly, wherein the magazine enclosure assembly also defines a passageway between the chamber and an outside of the magazine and wherein the chamber includes an indexing geometry that ensures proper alignment and positioning of the pre-pack when inserting the pre-pack into the magazine; and

an end adapted to be removable inserted into the non-lethal air gun.

9. A magazine assembly for use with the pre-pack assembly, the air gun and the non-lethal projectiles of claim 1 , the magazine comprising:

the pre-pack assembly of claim 1 ;

a magazine enclosure assembly that defines a chamber that receives the pre-pack assembly, wherein the magazine enclosure assembly also defines an opening that a feeder extends through when the pre-pack is inserted into the magazine and a passageway between the chamber and an outside of the magazine and wherein the chamber includes an indexing geometry that ensures proper alignment and positioning of the pre-pack when inserting the pre-pack into the magazine; and

an end adapted to be removable inserted into the non-lethal air gun.

10. A magazine assembly for use with the air gun and the non-lethal projectiles of claim 1 , the magazine comprising:

the pre-pack assembly of claim 1 ;

a magazine enclosure assembly that defines a chamber that receives the pre-pack assembly, wherein the magazine enclosure assembly also defines an opening that a feeder extends through when the pre-pack is inserted into the magazine and a passageway between the chamber and an outside of the magazine and wherein the chamber includes an indexing geometry that ensures proper alignment and positioning of the pre-pack when inserting the pre-pack into the magazine;

a sealing member adapted to seal the gas canister from external leakage;

a portal adapted to fluidly connect the gas canister to the magazine; and

an end adapted to be removable inserted into the non-lethal air gun, wherein the end includes a gas seal adapted to fluidly connect the magazine and the air gun to transfer gas from the magazine to the air gun when the magazine is inserted in the air gun.

11. The magazine assembly of claim 10 , further comprising:

a door that covers the passageway, wherein the door is pivotally coupled to the magazine enclosure assembly on a first end of the door; and

a multi-position latch positioned on a second end of the door opposite the first end, wherein the multi-position latch defines an open state where the pre-pack can be inserted and removed from the chamber, an intermediate state where the pre-pack cannot be inserted or removed from the chamber but the pre-pack can move within the chamber along its longitudinal axis, and a closed state where the pre-pack cannot be inserted or removed from the chamber and the pre-pack cannot move within the chamber along its longitudinal axis.

12. The magazine assembly of claim 11 , wherein moving the multi-position latch from the intermediate state to the closed state moves the gas cylinder into engagement with the portal and fluidly connects the gas canister to the magazine.

13. The magazine assembly of claim 12 , wherein the portal comprises a needle that pierces the gas canister when the multi-position latch is moved to the closed state from the intermediate state.

14. The magazine assembly of claim 11 , wherein the multi-position latch, in the intermediate state, is adapted to block passage of the pre-pack and gas canister in the event that the pre-pack or gas canister is released from engagement with the portal and the sealing member while the gas canister contains pressurized gas.

15. The magazine assembly of claim 10 , further comprising a gas regulator system that reduces the pressure of the gas passing through the regulator system so that the pressure of the gas passed from the magazine to the air gun is less than the pressure of the gas in the gas canister.

16. The magazine assembly of claim 15 , further comprising an adjustment mechanism, accessible from the outside of the magazine that adjusts the pressure of the gas passing through the regulator system.

17. The magazine assembly of claim 10 , wherein the magazine looks and feels like a conventional rifle or pistol magazine.

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.

19. The air gun of claim 18 , wherein the air gun produces the same felt recoil as a conventional live-fire rifle or pistol.
