Delta Armory M4 SilentOps Charlie Eagle 7" Airsoft Gun — Tan — Black

The Delta Armory M4 SilentOps Charlie Eagle in the 7" version (short outer barrel, ABS receiver) is an electric airsoft gun in CQB format, designed for players who need a compact and manoeuvrable replica for close-quarters environments. With an overall length ranging from 715 mm to 800 mm depending on stock position and a weight of 2110 g, it sits in the balanced mid-size airsoft gun category.

The propulsion system is a version 2 gearbox in QSC (Quick Spring Change) configuration, featuring 14 piston teeth, 7 mm metal bearings and a metal spring guide: the combination ensures stable power transfer and allows spring replacement without fully disassembling the unit. Muzzle velocity is 115 m/s, compatible with BBs weighing 0.25 g to 0.28 g — a range that offers a good balance between flat trajectory and flight stability. The integrated MOSFET protects the contacts from overheating and allows full use of the pre-fitted T-Dean connector, which reduces voltage drop compared to Mini-Tamiya connectors. The system is non-blowback: those seeking the feedback of the bolt cycle will not find it here, but gain in quietness and energy efficiency.

The inner barrel measures 330 mm and the hop-up chamber is plastic with manual adjustment. The rail system is RIS/Picatinny, making it straightforward to add optics, torches and grips. The included plastic mid-cap magazine holds 120 BBs: the lower capacity compared to hi-caps eliminates the typical rattle noise during movement, at the cost of fewer BBs available before reloading. The battery is not included; the buffer tube compartment accepts stick-type batteries — check the length before purchasing.
