Competition Features and CNC Precision

Every external component of the CTHULHU is designed for speed and tactical superiority. The aggressively styled CNC "Game Changer Pro Squared" Compensator not only completes the race aesthetic but also covers the 14mm CCW male threaded outer barrel, making it ready for any tracer unit or suppressor upgrade. For control, the integrated "Cornerstone" CNC Thumb Rest (Gas Pedal) and the textured Tandemkross Hivegrip lock the shooter's hand in place, helping manage the snappy recoil delivered by the lightweight, CNC-machined bolt carrier. The Skeletonized Competition Trigger provides a flat face and short travel distance, enabling the fast, razor-sharp response critical for rapid semi-auto fire strings.

Unbeatable Compatibility and Versatility

The core internal mechanism of the CTHULHU is a revolutionary feature: it is fully compatible with the massive ecosystem of Action Army AAP-01 upgrade parts. This grants the user unparalleled access to aftermarket components, from TDC hop-up units and high-flow valves to enhanced springs, ensuring the pistol is completely future-proof for custom tuning. The pistol also features fully functional Semi-Automatic and Full-Automatic firing modes, easily switched via the fire selector, transforming it into a high-rate-of-fire option for CQB emergencies. Furthermore, the included Red Dot Mount Plate and adjustable "Eagle Eye" Fiber Optic Sights ensure immediate readiness for any sighting system

Customisable Features

The upper is a unique Lancer design featuring a spiral-fluted outer barrel, removable 20mm Picatinny rail and 14mm CCW male threaded outer barrel ready for tracers, compensators or suppressors. The set includes the “Game Changer Pro” compensator, the red metallic “Halo” ring charging handle and a micro red-dot sight plate (RMR/Docter/Noblex footprints supported) all supplied in a protective polymer hard case.

Aethetic Excellence

Down low, the licensed Tandemkross lower provides the “Hive Grip” hex texture, a skeletonised competition trigger with overtravel adjustment, the large “Titan” magazine release, the extended “Bolt Keeper” and a gas-pedal style thumb rest — all designed for ultra-fast, repeatable target acquisition and control during rapid fire. Practicality meets flair: ambidextrous controls, repositionable receiver rail (mount on bottom), adjustable sights, lanyard loop and a threaded barrel make this pistol as usable as it is eye-catching.

Out of the box the CTHULHU is ready to run, tune and show off — and because it’s AAP-01 compatible internally, parts and performance upgrades are widely available for players who want more.
