An adapter for airsoft guns includes a housing comprising a single, integrally formed plastic element, the housing having an upper portion configured to mate with a magazine well of the airsoft gun, an air reservoir located within the housing for holding pressurized gas, an air inlet configured for allowing ingress of pressurized air from an attached gas canister, an air outlet configured for allowing egress of pressurized air from the air reservoir, a piston valve between the air reservoir and the air outlet configured for preventing airflow from the air reservoir to the air outlet when in the rest position, and allowing temporary airflow from the air reservoir to the air outlet when contacted by a firing pin of the airsoft gun, a projectile inlet and a projectile outlet. The adapter further includes a projectile illuminating system for illuminating projectiles such that the projectiles glow in the dark.

A pre-pack assembly for use with an air gun and for use with a magazine that is removably insertable into the air gun, the pre-pack assembly includes a pre-pack that contains a gas canister, wherein inserting the pre-pack into the chamber of the magazine fluidly connects the gas canister with the magazine.

A smart magazine includes a gas chamber, a processor, a memory, a wireless transceiver, a battery, and a shot counter. The shot counter determines the quantity of virtual bullets in the smart magazine. The quantity of virtual bullets is between zero and a parameter defined value for a maximum magazine capacity of virtual bullets. The shot counter decreases the quantity of virtual bullets by one each time the COTS pistol is fired. When the quantity of virtual bullets is zero per the shot counter, the smart magazine is configured to prevent the COTs pistol from firing. The smart magazine lacks a chamber for non-combustive round objects which the COTS pistol is configured to fire. The smart magazine is a direct replacement for a COTS magazine for the COTS pistol. The COTS magazine stores the non-combustible round objects that the COTS pistol is configured to fire.
