Heretic Labs Article I MTW-Spec HPA Speedsoft Rifle – Stockless 6" Carbon Barrel

Minimalist Speedsoft Performance: The Heretic Labs Article I sheds all nonessential components for pure, competition-grade HPA performance. No stock, no rail, no dead weight — just a skeletonized MTW-spec CNC receiver, precision carbon fiber barrel, and blazing-fast trigger response in a 2.1 lb pistol-format powerhouse.

INFERNO Gen 2 Engine with Binary Fire Mode: At its core is the legendary Wolverine INFERNO Gen 2 HPA engine, blacked out and pre-programmed by Heretic Labs to include semi, full-auto, and binary modes. The non-Bluetooth FCU allows full trigger-based programming with clean, intuitive fire mode selection.

Ultra-Light Carbon Fiber Front End: The front of the Article I is anchored by a genuine carbon fiber barrel housing a 150mm inner barrel. Combined with its stripped-down receiver, this rifle delivers peak speed and control for close-quarters environments.

High-Speed CNC Trigger with Delrin Bearing: A custom CNC-machined speed trigger offers adjustable pre-travel, post-travel, and actuation, riding on a Delrin low-friction bearing for smooth, crisp pulls every time — a major upgrade over traditional microswitch setups.

Stockless QD Rear Plate: Instead of a buffer tube, the Article I includes a rear Picatinny stock adapter plate with an integrated QD sling mount. Add your own minimalist stock, sling, or leave it bare for pure maneuverability.

Built on MTW-Spec Platform: The Article I maintains full compatibility with MTW aftermarket parts and real-steel accessories. It accepts standard MTW-spec hop-ups, mags, and internal upgrades, giving you endless room to evolve your setup.
