Heretic Labs Article IV

Heretic Labs Article IV

Heretic Labs occupies the very top of the premium HPA airsoft market. The Article IV is their flagship — a rifle built for players who have tried everything else and want something that truly sets the benchmark. Every component is selected and assembled with uncompromising attention to performance, durability, and feel.

Premium Construction Throughout

• Aircraft-grade aluminium receivers — precision CNC machined, not cast
• HPA-powered — consistent FPS across every shot regardless of temperature, tank pressure, or rate of fire
• Elite trigger response — the tactile difference between a Heretic Labs build and a standard AEG is immediately apparent
• M4-compatible — standard AEG magazines accepted
• Built in small batches — not a mass-produced product; quality control is hands-on at every stage

Who Builds These?

Heretic Labs attracts the kind of players who measure performance in millimetres on a target and expect their equipment to perform exactly the same in January rain and August heat. The Article IV is the choice of experienced HPA players who understand that at this level, the gun is the limiting factor — and they want it removed.

What’s Included

The Article IV ships ready to run on an external HPA rig. Internal tuning is available at Airsoft Direct — speak to our team if you want the gun set up for a specific site’s power limit before it ships to you.

External HPA rig required. Suitable for 18+ only.
