Primary Airsoft HPA/X9 Adapter for Hi-Capa Pistols

Elevate your Airsoft gameplay with this innovative adapter designed to level the playing field between pistols and AEGs. Compatible with Tokyo Marui, WE-Tech, EMG, and other Hi-Capa gas blowback pistols, this adapter seamlessly integrates HPA (high-pressure air) and X9 AEG magazines into your setup—allowing you to match magazine capacity against advanced electric guns while maintaining precision and reliability.

Engineered for Performance
Crafted from lightweight glass-reinforced nylon polymer with CNC-machined aluminum components, this adapter offers durability without compromising portability. Its universal design supports both WE-Tech/Armorer Works and Tokyo Marui magazine configurations, ensuring flexibility for diverse setups. The included Foster quick disconnect fitting (US standard 1/8 NPT) simplifies hose connections, while a longer 2.5mm hex screw ensures secure installation. A plastic spacer is also provided to customize slide stroke length for optimal performance.

Key Benefits
– Enhanced Capacity: Use high-capacity X9 or HPA magazines (with upgraded springs) for extended gameplay without reloading
– Pressure Optimization: Designed for low-pressure regulators (0-140 psi), ensuring safe operation at 120 psi (green gas equivalent)
– Jam-Proof Design: The extended feed tube on Tokyo Marui versions prevents double-stacking jams
– Universal Fit: Works with 5.1 magazines on Hi-Capa pistols (including 4.3 models with 5.1 mags installed)

Installation & Safety
Install on a 5.1 magazine baseplate for compatibility; not compatible with WE-Tech 4.3 short baseplate mags. Avoid exceeding 140 psi to prevent wear on internal components. Pair with a paintball tank regulator, Foster hose, and BBs for full functionality—gun and magazine sold separately.

Stay Competitive
Whether you’re a skirmish veteran or new to Airsoft tactics, this adapter delivers unmatched versatility for Tokyo Marui Hi-Capa owners seeking to upgrade their game. Perfect for airsoft fields, events, or backyard training—your next match starts here.
