CTM HI-CAPA Gas Blowback Pistol HPA-MAG Adapter for M4 Magazines

Upgrade Your Hi-CAPA Airsoft Experience with CTM’s HPA/M4 Magazine Adapter

Transform your Hi-CAPA gas blowback pistol into a high-performance powerhouse! Our precision-engineered adapter lets you harness the efficiency of HPA systems and versatile M4 AEG magazines—perfect for extended skirmishes or competitive airsoft events.

Built Tough for Reliable Play
Crafted from ultra-lightweight glass-reinforced nylon polymer and reinforced with CNC-machined 6061 aluminum magazine retention, this adapter withstands intense field use. The heavy-duty 1215MS steel HPA valve ensures leak-free operation, while tapered threads guarantee a secure seal under pressure.

Smart Design, Superior Control
Unlike generic adapters, our patented mechanism securely holds BBs until you trigger release—eliminating misfeeds and wasted ammo mid-game. Pair it with any quality M4 AEG magazine featuring robust springs (we recommend superfeed springs for peak consistency).

Optimized Performance & Safety
Designed for WE, Tokyo Marui, KJ Works, and other Hi-CAPA-compatible pistols. Operate safely at standard green gas pressures (~120 PSI) using a low-pressure regulator (0-140 PSI max). Includes essential accessories: gasket ring, hex key, and universal feed tube—ready to install straight from the box.

Pro Tips for Longevity
– Avoid exceeding 140 PSI to protect internal components
– Never store magazines fully loaded to prevent spring fatigue
– Ideal for airsoft fields requiring rapid reloads or HPA efficiency
