KWC M11 Airsoft SMG (Non-Blowback - CO2 Powered - KWC-KC-55HN)
Unleash stealthy, high-efficiency firepower in a lightweight profile with the KWC M11 (Non-Blowback - CO2 Powered - KWC-KC-55HN). Styled after the iconic Ingram MAC-11 submachine gun, this non-blowback (NBB) CO2 airsoft replica maximizes velocity and shot count per capsule by funneling 100% of the CO2 gas directly behind the BB rather than wasting energy cycling a heavy bolt.
Featuring an agile, high-impact polymer chassis, a collapsible metal wire stock, and a heavy-duty CO2 metal magazine, the KC-55HN delivers exceptional cold-weather reliability, whisper-quiet stealth potential, and hard-hitting velocity. Whether carried as a formidable backup secondary or run as a high-speed primary, it offers rock-solid dependability when you need it most.
Non-Blowback CO2 Efficiency
The primary advantage of a non-blowback system lies in its raw mechanical efficiency. Without energy lost to a reciprocating bolt, the KWC M11 KC-55HN yields an exceptional number of shots per single 12g CO2 cartridge while maintaining high muzzle velocity and shot-to-shot consistency. This makes it an ideal sidearm or CQB primary for extended skirmishes where gas conservation and zero cold-weather "cool down" issues are paramount.
Iconic M11 Ergonomics & Extendable Wire Stock
Replicating the classic silhouette of the legendary MAC-11 submachine gun, this replica features a durable, impact-resistant composite chassis that keeps total weight under a comfortable 1 kg for lightning-fast target indexing. Equipped with a sliding metal wire stock, operators can instantly collapse the stock for tight room clearance or pull it out to stabilize longer-range shots down outdoor lanes.
Skirmish Durability & All-Weather Reliability
Powered by standard 12g CO2 cartridges inserted directly into the drop-free metal magazine, the KWC M11 punches well above its weight class. Because the NBB mechanism uses fewer internal moving parts than traditional gas blowback submachine guns, the system boasts superior structural longevity and operates seamlessly across all seasons—including freezing winter temperatures that render standard gas guns useless.
