CTM CNC Reaper Stock Mount Kit for TM Hi-Capa - Black

CTM TAC CNC Aluminium Reaper Conversion Kit for Tokyo Marui Hi-Capa 5.1 - Black

Transform your Tokyo Marui Hi-Capa 5.1 from a traditional sidearm into a high-tech, futuristic primary with the CTM TAC CNC Aluminium Reaper Conversion Kit. Purpose-built by CTM TAC for competitive speedsoft players, tournament shooters, and custom GBB builders, the Reaper Kit replaces your traditional slide assembly with an ultra-lightweight, fixed-outer chassis that delivers insane cycle speeds and pinpoint accuracy.

Precision CNC-machined from 6061-T6 aircraft-grade aluminium and weighing just 185 grams, this complete front-end conversion features aggressive skeletonized windows that expose your inner barrel while shedding maximum reciprocating mass. Because the top optics rail and outer chassis remain fixed during cycling, your red dot sight stays completely motionless while firing, giving you instantaneous red-dot tracking, zero sight movement, and blazing-fast follow-up shots in high-stress CQB matches.

Key Features

• Fixed Chassis & Non-Tilting Barrel Design: The outer frame and optic mount stay stationary while only the internal bolt cycles, keeping your red dot centred for lightning-fast target acquisition.
• Integrated Top Dead Centre (TDC) Hop-Up System: Built-in top-adjust TDC mechanism allows you to fine-tune hop pressure directly from the top rail, delivering completely even downward pressure for laser-straight trajectories with heavy BBs (.28g–.40g).
• Ultra-Lightweight 185g Skeleton Construction: Drastically reduces front-end weight compared to full aluminium slides, reducing wrist fatigue and accelerating target transitions.
• Precision 6061-T6 CNC Aluminium: Milled from solid aircraft-grade aluminium alloy to withstand high-pressure green gas and HPA setups without flexing or cracking.
• Integrated Top Picatinny & RMR Optic Footprint: Features a continuous top Picatinny rail alongside direct RMR mounting points for micro red dot sights.
• 14mm CCW Threaded Muzzle Interface: Comes equipped with standard 14mm CCW (Negative) muzzle threads for direct mounting of compact UV tracer units and muzzle flash simulators.
• Tokyo Marui Hi-Capa 5.1 Compatibility: Engineered for seamless drop-in fitment onto TM Hi-Capa 5.1 base frames and compatible aftermarket lower receivers.

Technical Specifications

BZ Tech Team Advice:

• TDC Hop-Up Tuning: Make minor quarter-turn adjustments to the TDC screw while test-firing on the range. The rigid top pressure arm eliminates sidespin, making it effortless to hop heavy BBs (.30g+) with extreme precision.
• Threadlock Security: High-velocity GBB and HPA cycling vibrations can loosen small mounting hardware over time. Always apply a single drop of medium-strength blue threadlocker to all optic rail and frame screws during assembly.
• HPA Speedsoft Primary: Pair the Reaper Kit with a lightweight internal blowback housing, an upgraded nozzle, and an HPA M4 magazine adapter to create an unstoppable, high-RPM race primary for indoor tournament arenas.
