## Abstract

An air-soft gun includes a grip; a high-pressure air canister disposed in the grip; and a remaining compressed air release device including a channel member threadedly secured to an end of the air canister and including an axial channel and a sealing ring; a rotatable cap releasably secured to the channel member; a biasing member fastened between the cap and the channel member; a striker including a needle on a first end, an internal passageway, an inlet proximate the needle and communicating with the passageway, an outlet proximate a second end and communicating with the passageway, internal threads on the passageway proximate the second end, and a threaded fastener driven through the cap into the internal threads to secure the cap to the striker. The inlet is blocked by the sealing ring in an inoperative position.

## Claims

### Claim 1

An air-soft gun comprising:
a pistol-grip;
a high-pressure air canister disposed in the pistol-grip; and
a remaining compressed air release device comprising an externally threaded, cylindrical channel member threadedly secured to an end of the air canister and including an axial channel and a sealing ring; a rotatable cap releasably secured to the channel member; a biasing member fastened between the cap and the channel member and urging against the channel member; a striker including a needle on a first end, an internal passageway, an inlet proximate the needle and communicating with the passageway, an outlet proximate a second end and communicating with the passageway, internal threads on the passageway proximate the second end, and a threaded fastener driven through the cap into the internal threads to secure the cap to the striker;
wherein the inlet is blocked by the sealing ring in an inoperative position of the remaining compressed air release device; and
wherein a clockwise rotation of the cap causes the sealing ring to unblock the inlet, thereby flowing compressed air in the pistol-grip to the outlet through both the inlet and the passageway.
