Delta Armory M4 Charlie M-LOK 10" Airsoft Rifle — Carbon

The Delta Armory M4 Charlie is a carbine-format airsoft gun with an overall length of 715–795 mm (stock extended or retracted), a 280 mm inner barrel, a 25 cm M-LOK handguard and a Carbon finish. Weighing 2100 g, it sits in the mid-range for balance and handling, suitable for both indoor training and outdoor skirmishes.

The gearbox is a V2 in QSC configuration, fitted with a 14-tooth piston, 7 mm metal bearings and a metal spring guide. These components improve resistance to mechanical wear compared to fully plastic setups. The stated muzzle velocity is 115 m/s, optimised for 0.25–0.28 g BBs: going below 0.25 g reduces trajectory stability, while exceeding 0.28 g can lower effective velocity without improving accuracy. The barrel thread is 14 mm counter-clockwise, compatible with most suppressors and muzzle brakes for airsoft currently available.

The body is made from ABS, keeping overall weight down and reducing maintenance costs compared to metal bodies, though it requires more care against direct impacts on the receiver. The power system uses a battery compartment in the buffer stick with a Small Tamiya connector; the airsoft gun has no MOSFET or ETU. Using an 11.1 V battery requires fitting a MOSFET or ETU beforehand to protect the contacts from high current. No battery or charger is included. The magazine is plastic, mid-cap format, holding 120 BBs.

Key features

• Adjustable length between 715 and 795 mm: adapts to configurations with a tactical vest or light kit without structural modifications.
• 25 cm M-LOK handguard frees up space on three sides for torches, front grips or laser pointers without additional adapters.
• V2 QSC gearbox with metal bearings and metal spring guide: the highest-stress points are already reinforced as standard, reducing the frequency of routine maintenance.
• Velocity of 115 m/s with 0.25–0.28 g BBs: meets common field limits for the rifle category and requires no spring-down before first use.
• 14 mm left-hand thread: compatible with the wide range of airsoft muzzle accessories without adapters.
• ABS body reduces the weight of the airsoft gun and lowers replacement costs in the event of surface damage, with the trade-off of less impact resistance compared to metal.
