Double Bell K-56 Gas Grenade for GP-25 Grenade Launcher, Copper

Room clearing just got a lot simpler. The K-56 is a 40mm gas grenade that dumps 36 rounds of green gas in one big blast when you launch it through a replica GP-25 launcher. One pop, and the room you were about to enter becomes a very different conversation.

How it works. The K-56 is a gas-only device — no BBs inside it. It holds 36 shots of green gas, and firing it through the GP-25 releases everything at once. The gas cloud fills a room, hits sensors, or masks movement the way a flash bang does visually. Players who use them treat them as area-denial tools: flush someone out of a corner, shut down a spawn room between rounds, or create enough noise and confusion that the rest of the entry doesn’t need to be graceful.

Building blocks. The shell is full CNC aluminum, which gives it some heft at 200 grams but means it won’t crack on the first launch. It’s a single grenade per purchase — the package includes the grenade shell and nothing else. You need a GP-25-compatible launcher to fire it, and you need green gas to fill it. Neither comes with it.

Filling and handling. Gas grenades fill through a small valve on the base. A gas gun with a fine-fill nozzle makes it easier, but a standard green gas can with a thin adapter works too. Fill until it stops taking gas — the K-56 holds more than most people expect, and a single canister rarely tops one off. Give it a shake or two after filling so the gas distributes inside the chamber. It works at any angle, but don’t expect it to fire if the valve is blocked or the channel is clogged with silicone residue from a sloppy fill. A quick spray of valve cleaner before filling helps.

What it isn’t. This isn't a throw-and-pop grenade you carry in your vest and palm-launch mid-fight. It lives in the launcher, goes off on command, and does one job really well. If you need something to toss by hand, look at a CO2 grenade or a flash bang instead.

Availability note. Double Bell grenades are a known quantity in the hobby — reliable enough for regular use and common on fields where grenades are allowed. Check your field's rules first: some don't permit grenades at all, and some require specific fills or restrict them to designated arenas. You don't want to show up with a full K-56 on a field that bans them.
