Delta Armory M4 Charlie M-LOK 8" Airsoft Rifle — Carbon

The Delta Armory M4 Charlie is a carbine-format airsoft gun featuring an M-LOK handguard of 8" and an overall length adjustable between 615 mm and 690 mm thanks to the adjustable stock. Weighing 1980 g and with a muzzle velocity of 115 m/s, it sits in the ready-to-use segment for players looking for a compact AR-15 without any immediate modifications.

At the core is a version 2 gearbox with QSC system, built with 14 teeth on the piston, 7 mm metal bearings and a metal spring guide. These three elements work together to absorb internal stress during the firing cycle: the plastic piston reduces the mass the motor must reverse with each shot, but it should be considered the highest-wear component over time, especially if a higher-rate spring is fitted. The manufacturer explicitly recommends quality M120 springs to avoid damage caused by springs that do not meet their stated power rating.

The connector is Small Tamiya and the battery compartment is housed in the buffer tube, compatible with stick batteries. The airsoft gun has neither a MOSFET nor a processor unit: anyone intending to fit an 11.1 V LiPo battery must install a MOSFET or ETU unit beforehand, or risk burning out the trigger group. The included magazine is a plastic mid-cap holding 120 BBs. The suppressor thread is 14 mm counter-clockwise, the standard for most compatible AR accessories.

Key features

• Adjustable length between 615 and 690 mm: the carbine format balances manoeuvrability and stability without requiring any modifications.
• V2 QSC gearbox with metal spring guide and metal bearings: the internal components are sized for continuous use, even with moderate spring upgrades.
• 8" M-LOK handguard: the free surface accepts torches, lasers and vertical grips without adapters, keeping a slim profile.
• Inner barrel 230 mm, optimised for BBs weighing 0.25 g to 0.28 g: the recommended weight balances trajectory and hop-up performance.
• Small Tamiya connector included, but using an 11.1 V LiPo requires adding a MOSFET — a detail to plan before first use.
• 14 mm counter-clockwise thread: compatible with most aftermarket suppressors and muzzle devices for the AR platform.
