Echo1 General Assault Tool (GAT) AEG Sub Machine Gun (Black - JP-103)

The Icon of Close-Quarters Firepower

If you are looking to break away from traditional M4 and MP5 platforms, the Echo1 General Assault Tool (GAT) brings classic action-hero aesthetic straight to the modern airsoft field. Distributed by Jag Precision / Jag Arms, this TEC-9 style submachine gun delivers exceptional maneuverability without sacrificing power. Weighing in at just 3.5 lbs (1.58 kg) and measuring a compact 13.5 inches in overall length, it provides blisteringly fast weapon handling—allowing you to slice corners, breach tight doorways, and effortlessly move through dense CQB arenas.

Full-Sized 8mm Gearbox Performance

Unlike standard AEPs (Electric Airsoft Pistols) that suffer from low FPS and sluggish performance, the Echo1 GAT is built around a true full-performance internal drivetrain. Hidden inside its compact frame is a custom 8mm reinforced metal gearbox paired with a short-type motor.

Clocking in at 330–350 FPS with 0.20g BBs, this compact SMG out-muscles typical gas blowback sidearms and holds its own against full-sized assault rifles. The system is LiPo-ready out of the box, delivering responsive cycling and high-volume suppression downrange.

Modular Ergonomics & M14x1 CCW Threading

The GAT’s hybrid construction perfectly balances structural durability and lightweight handling. The upper receiver, outer barrel assembly, sling loops, and high-capacity magazines are constructed from solid metal, while the lower frame is molded from high-impact reinforced polymer.

The front vertical foregrip serves a dual purpose: it acts as a steady indexing point for weapon control and functions as the integrated battery compartment. Underneath the heat-shield barrel shroud sits an integrated 20mm Picatinny rail section, perfect for mounting tactical flashlights or lasers. Underneath the removable US factory orange tip, standard M14x1 CCW (14mm Counter-Clockwise) threads are available, allowing you to easily spin on mock suppressors, extension tubes, or high-speed tracer units for night-ops play.
