Delta Armory M4 SilentOps 8" Charlie Airsoft Gun — OD — Green

The Delta Armory M4 SilentOps 8" Charlie is a compact AEG designed for dynamic airsoft and CQB. With an overall length between 680 and 760 mm (stock retracted and extended), an inner barrel of 230 mm and a weight of 2050 g, it strikes a balance between handling and genuine perceived mass. The M-LOK mounting system on the handguard allows you to customise the layout without adding unnecessary weight. Available in OD green.

The gearbox is a V2 QSC with 14 teeth on the piston and 8 mm metal bearings: the metal spring guide and pin increase durability under heavy use, while the piston head and nozzle in technical polymer absorb impact stress cycle after cycle. Muzzle velocity is 115 m/s with 0.25–0.28 g BBs, which represents the ideal compromise between a flat trajectory and gearbox load at this barrel length. The muzzle thread is 14 mm negative (CCW), compatible with the vast majority of suppressors and compensators for M4 airsoft guns on the market.

The airsoft gun has no integrated MOSFET or processing unit: with batteries up to 7.4 V LiPo in stick format (housed in the buffer tube) it runs without modification. The manufacturer explicitly recommends fitting a MOSFET or ETU before connecting an 11.1 V battery, to protect the contacts and gearbox. Spring grade M120 is recommended; incorrect spring grades can cause damage to the internal structure. The plastic mid-cap magazine holds 120 BBs and requires no continuous manual winding, unlike hi-caps. Always wear eye protection during use; regular inner barrel cleaning and hop-up maintenance extend the operational life of the airsoft gun.

Key features

• Adjustable length between 680 and 760 mm: suited to CQB with stock folded, more stable in open areas with stock extended
• Inner barrel of 230 mm and velocity of 115 m/s: optimal balance for 0.25–0.28 g BBs without overloading the gearbox
• V2 QSC gearbox with 8 mm metal bearings and metal spring guide: greater resistance to repeated cycling compared to entry-level versions
• M-LOK mounting on the handguard: compatible with standard accessories without additional adapters
• 14 mm negative thread: allows direct fitting of suppressors and devices for M4 airsoft guns
• No integrated MOSFET: ready to use with 7.4 V LiPo; MOSFET or ETU required before using 11.1 V batteries
