Delta Armory M4 SilentOps 8" Charlie M-LOK Airsoft Gun — Black

The Delta Armory M4 SilentOps 8" Charlie is a compact AEG airsoft gun designed for players looking for a manoeuvrable platform on CQB fields or in tight indoor environments. With an overall length adjustable between 680 and 760 mm — thanks to the collapsible stock — and a weight of 2050 g, it offers a realistic feel whilst remaining easy to carry. The 230 mm inner barrel and a muzzle velocity of 115 m/s place it well within the limits typical of standard indoor and outdoor fields, with recommended BBs between 0.25 and 0.28 g.

The gearbox is a V2 in QSC configuration, featuring 14 piston teeth, 8 mm metal ball bearings and a metal spring guide: this combination delivers smoother power transfer than plastic-bearing versions and reduces wear over time. The piston, nozzle and hop-up chamber are plastic — a choice that keeps weight and overall cost down, but one worth considering for anyone planning to run heavier springs, as internal component replacement may be required. The manufacturer recommends quality M120 springs to avoid excessive stress on the internals.

The handguard accepts accessories via the native M-LOK system along its full length, making it straightforward to mount torches, foregrips or other modules without adding unnecessary weight. The receiver and handguard are ABS — lightweight but not suited to heavy impacts in the way a metal chassis would be. Power comes from a stick battery in the buffer tube — not included — via a small Tamiya connector; the manufacturer specifies that using 11.1 V batteries requires prior installation of a MOSFET or ETU unit, neither of which is fitted as standard. A plastic mid-cap magazine holding 120 BBs is included.

Key features

• Adjustable length from 680 to 760 mm: adapts to your kit and shooting position without swapping the stock.
• 230 mm inner barrel and 115 m/s muzzle velocity: compatible with most CQB field limits using 0.25 g BBs.
• Native M-LOK system: accessories mount without adapters or additional rails.
• V2 QSC gearbox with 8 mm metal ball bearings: the internals are already geared towards progressive upgrades.
• Stick battery in the buffer tube: a compact setup that does not alter the external dimensions of the gun.
• 11.1 V use requires MOSFET or ETU installation: a point to consider before purchase if you plan to run high-voltage LiPo batteries.
