Delta Armory M4 Predator Charlie KeyMod 10" Airsoft Rifle — Tan — Black

The Predator Charlie is a carbine-format airsoft gun built on the M4/AR15 platform, featuring a KeyMod handguard and a two-tone Tan finish. With an adjustable length between 725 mm and 805 mm thanks to the retractable stock, and a weight of 2,250 g, it sits firmly in the compact CQB category for players who want manoeuvrability without sacrificing handguard customisation.

At the heart of the replica is a Version 2 gearbox with QSC system, 14 piston teeth and 7 mm metal ball bearings: a combination that delivers a smooth firing cycle and solid energy transfer to the spring. The inner barrel measures 320 mm, and the manufacturer recommends BBs weighing 0.25 g to 0.28 g for the best trajectory at a muzzle velocity of 115 m/s. The thread is 14 mm CCW, compatible with most aftermarket suppressors and flash hiders for the M4 platform.

The body is made from ABS, keeping weight and cost down but representing a trade-off compared to metal bodies: it offers less structural rigidity under load and a less cold feel in the hand, though it holds up well under normal airsoft field use. Power comes from a stick battery in the buffer tube via a small Tamiya connector — a common format, but one that limits capacity compared to nunchuck or wide-stick LiPos; it is worth checking your battery dimensions before buying. A plastic mid-cap magazine holding 120 BBs is included; there is no MOSFET or processor fitted, so any electronics upgrade starts from scratch.

Key features

• Adjustable length from 725 to 805 mm via retractable stock: quick to adapt to the playing field or the operator.
• KeyMod system on the 10" handguard: lets you mount accessories only where needed, saving weight compared to a full-length rail.
• 14 mm CCW thread: compatible with the standard range of aftermarket M4 suppressors and compensators.
• V2 QSC gearbox with 14 piston teeth and metal bearings: smooth cycle and ready for standard M4-platform upgrades.
• Muzzle velocity of 115 m/s with 0.25–0.28 g BBs: the range-to-accuracy balance typical of CQB and mixed outdoor play.
• ABS body: low weight at the cost of maximum rigidity — a sensible choice for airsoft field use.
