Delta Armory M4/AR15 RIS Charlie Airsoft Gun — Black

The Delta Armory M4/AR15 RIS Charlie is an electric airsoft gun with an adjustable length, designed for players looking for a solid and versatile AR15 platform without sacrificing practicality in the field. With an adjustable length between 800 mm and 890 mm and an inner barrel of 380 mm, it suits medium engagement distances, fitting the most common use case for both outdoor play and moderate CQB.

The gearbox is the V2 QSC version with 14 teeth on the piston and 7 mm metal bearings: the metal spring guide and spring guide rod ensure a more stable cycle compared to fully plastic solutions, reducing the tendency to slip under load. The muzzle velocity of 115 m/s is compatible with the majority of fields. The manufacturer recommends BBs of 0.25 g to 0.28 g to balance trajectory and stability with this setup; lighter BBs are more affected by wind and the hop-up backspin. The muzzle thread is 14 mm negative, the most common standard on M4 platforms, ensuring broad compatibility with aftermarket suppressors and tracer units.

The ABS body is lighter than a metal receiver — the overall weight of 2545 g is modest for a rifle of this size — but it is also less rigid under torsion. Those who prefer structural rigidity should consider replacing the receiver; those who prioritise lightness and handling will find the trade-off favourable, especially with crane battery configurations. The integrated RIS/Picatinny system allows lights, laser sights and vertical grips to be fitted without additional adaptors. The plastic 120-round mid-cap magazine is included: mid-cap means no noise from loose BBs, but the feed button must be pressed before each load.
