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

The Delta Armory M4 Charlie M-LOK 10" is an electric airsoft rifle in a compact carbine configuration, designed for players looking for a short AR-15 platform for CQB fields or as a base for customisation. With an overall length ranging from 715 mm to 795 mm depending on stock position, and a 280 mm inner barrel, it offers excellent manoeuvrability in tight spaces without sacrificing a muzzle velocity of 115 m/s using BBs weighing 0.25–0.28 g.

The receiver is made from ABS, keeping the total weight down to 2100 g while maintaining full compatibility with standard AR-15 accessories: the M-LOK rail on the 10" handguard accepts torches, foregrips and bipods without adapters. The propulsion system is based on a version 2 gearbox in QSC (Quick Spring Change) configuration, allowing spring replacement without fully stripping the internals. The 7 mm metal bearings reduce friction on the gears, while the metal spring guide prevents collapse under load. The piston, piston head and nozzle are plastic: adequate for standard use, but worth replacing with reinforced parts if high-tension springs are planned.

Power is supplied by a stick battery in the buffer tube via a Mini Tamiya connector. The gearbox has no integrated MOSFET or ETU: on a 7.4 V LiPo battery the system runs as standard, but the manufacturer states that an external MOSFET is required when using an 11.1 V pack in order to protect the contacts. The included magazine is a plastic mid-cap holding 120 BBs. The hop-up is adjustable; the chamber is plastic. The system has no blowback.
