The DELTA Vanguard Pathfinder combines traditional M4 styling with modern electronic performance control, creating a rifle that looks classic but performs at the next level.

At the heart of the Pathfinder is the Vortex programmable ETU system. This advanced electronic trigger unit transforms the fire selector into a configurable control interface, allowing players to choose between semi-only, 2-round burst, 3-round burst, 4-round burst, 5-round burst, binary trigger mode and full auto. This adaptability makes the Pathfinder suitable for varying site rules, play styles and engagement environments.

Built on the reinforced DELTA Version 2 gearbox platform, the Pathfinder maintains mechanical durability while enhancing trigger response and electrical efficiency through Deans wiring. The 18:1 steel gear set supported by 8mm ball bearings ensures smooth cycling, while the Vortex ETU provides crisp, consistent trigger break and reset.

Accuracy is supported by the rotary hop unit paired with a 50° hop rubber and precision 6.03 mm inner barrel. This setup promotes stable BB flight and reliable grouping, whether engaging in close-range exchanges or stretching into mid-field distances.

The nylon fiber polymer construction across the upper receiver, lower receiver and handguard reduces weight while maintaining structural strength. The classic carbine handguard and fixed front sight base give the Pathfinder a familiar M4 silhouette, while the modern skeletonised stock reduces rear weight and improves balance.

The M90 quick-change spring system ensures adaptable power tuning without full gearbox disassembly, adding flexibility for different site requirements.

The DELTA Vanguard Pathfinder is built for players who want traditional aesthetics combined with modern programmable performance and enhanced trigger control.

Range Overview:
