Description
Double Bell AK Series 40mm Under-Barrel Grenade Launcher (Inc. Gas Grenade – Black – K-55)
This Double Bell under-barrel launcher, model K-55, is designed to fit AK-series airsoft rifles, giving them the classic look of the Soviet-pattern grenade launchers carried beneath AK rifles. It is finished in black and supplied with a gas grenade shell, so once you have filled the shell with gas and BBs you are ready to start using it.
Double Bell is a well-known manufacturer of affordable AK and M4 AEGs and accessories, and this launcher is a natural partner for its AK range and many other AK-pattern replicas. It is a popular choice for players building an Eastern Bloc or Russian-themed loadout, as well as anyone who simply wants more firepower and variety from their AK.
How it works
The launcher itself has no gas tank, battery or hop-up. Instead, power comes from a 40mm airsoft gas grenade shell, which holds both gas and a load of BBs. You charge the shell with gas, fill it with BBs, load it into the launcher and fire with the launcher’s own trigger. The shell releases its gas in one go and throws a spread of BBs, which is ideal for clearing rooms, catching groups of players behind cover or forcing an opponent to move.
Because the shell provides the power, the range and spread you get depend on the shell, the gas and the BBs you use. Carrying a few extra pre-loaded shells means you can reload quickly between shots.
Handling
Mounted under the front of the rifle, the launcher gives your support hand a solid place to grip and adds a little weight at the front, which helps steady the rifle. Being black, it blends with traditional AK furniture or modern black AKs alike. A sling is recommended, as any under-barrel launcher adds weight to the front end.

Compatibility
Designed for AK-series airsoft rifles. AK replicas vary between manufacturers in their handguard and barrel dimensions, so please check your rifle’s model before ordering, and contact us if you are unsure. Extra 40mm airsoft gas shells can be used, but shell lengths and diameters vary between brands, so check fit before buying spares.
Care and maintenance
Keep the launcher’s breech and moving parts clean and free of grit, and use a drop of silicone oil on moving parts occasionally. Look after the shell by filling it only with airsoft gas, putting a little silicone oil on the fill valve and seals regularly, and storing it with a small amount of gas inside to keep the seals supple. Never leave a loaded shell in the launcher after play.
Who is it for?
This launcher suits AK owners who want to take on a grenadier or support role, milsim players building a realistic Eastern Bloc loadout, and anyone who wants to add some variety to their game without buying a separate launcher platform.
Please note: The rifle, gas and BBs are not included. Always wear suitable eye and face protection, and check your site’s rules on launchers and grenade shells before play.
