KWC M11 (Non-Blowback – CO2 Powered – KWC-KC-55HN)
The KWC M11, model KWC-KC-55HN, is a CO2-powered, non-blowback airsoft replica of the M11 (MAC-11) style machine pistol. The M11 is one of the most recognisable compact weapons ever made, with its boxy receiver, magazine in the grip and very short overall length.
KWC is a Taiwanese manufacturer known for affordable, reliable CO2 replicas. Its M11 gives players a compact, distinctive sidearm or close-quarters weapon that is inexpensive to run and easy to look after.
How it works
The M11 runs on CO2. Each pull of the trigger releases a small amount of gas to fire a BB. Because it is non-blowback, there is no moving bolt to cycle, so every bit of gas goes into the shot. That makes it economical, and CO2 performs far better than green gas in cold weather.
Handling
The compact M11 layout puts the magazine in the grip, keeping the replica short and easy to handle in tight spaces. It can be fired one-handed like a pistol or steadied with the support hand for better accuracy. The distinctive shape makes it a favourite for themed loadouts and film-inspired characters.
Getting started with CO2
Fitting a capsule is quick: put a drop of silicone oil on the tip of a new CO2 capsule, fit it as shown in the supplied manual, then load BBs and you are ready to shoot. Shoot at a safe backstop such as a BB trap or a box packed with old cloth, and start with paper targets at five to ten metres. When you have finished, remove the capsule rather than leaving the seals under pressure.
Ideal uses
The KWC M11 is a fun, characterful replica for target shooting and plinking, and it works well as a compact secondary in CQB games. Its simple non-blowback design makes it easy to maintain.

Compatibility
Uses CO2 and standard 6mm BBs; 0.20g BBs are a sensible choice. Use KWC magazines made for this M11 model; please ask us before buying spares.
Holsters and slings for M11/MAC-style replicas vary, so check fit before buying.
Care and maintenance
CO2 replicas are simple to maintain, but the seals benefit from a little care. Put a drop of silicone oil on the tip of each new 12g CO2 capsule before fitting it; the gas carries the oil through the seals and keeps them supple. Wipe the replica down after use and run a cleaning rod with a clean patch through the inner barrel from time to time.
Do not leave a part-used capsule in the replica for long periods; when you have finished shooting, fire off or carefully release the remaining gas and remove the capsule so the seals are not under constant pressure. Store indoors at room temperature and use good quality seamless 6mm BBs to protect the barrel and hop-up.
Who is it for?
The KWC M11 is for players and collectors who want a distinctive, compact replica of a classic machine pistol that is cheap to run and reliable in the cold.
Please note: CO2 capsules and BBs are not included unless stated above. Always wear suitable eye and face protection and check the power and safety rules at your site before play.
