Airtac HPA Adapter Hi-Capa to M4

Description

Airtac HPA Adapter: Hi-Capa to M4 Magazine Conversion

The AirTac HPA Adapter Hi-Capa to M4 is a professional-grade airsoft accessory engineered to revolutionize the performance and capacity of your Hi-Capa gas blowback pistol. By converting your pistol to utilize High-Pressure Air (HPA) and readily available M4 AEG magazines, this adapter eliminates the inconsistencies of traditional gas systems, offering unparalleled consistency and capacity for competitive and extended skirmishes.

Key Features & Performance Benefits

Massive Ammunition Increase: Allows your Hi-Capa to feed from standard M4 AEG magazines, dramatically increasing your ammunition capacity compared to standard gas magazines.

Consistent FPS & Accuracy: Running on HPA eliminates the “cooldown” effect inherent to green gas/propane, delivering a stable and consistent Feet Per Second (FPS) and improved accuracy from your first shot to your last.

Durable, Precision Construction: Made from durable injection-moulded polymer or high-impact resistant materials (often incorporating CNC components like the mag release and feed tube in next-gen models) for a secure, precise fit and long-term durability.

Instant HPA Setup: Features a pre-installed US-thread HPA fitting for quick and direct connection to most HPA air tank and regulator setups.

Reliable Feeding: An integrated BB-retention system minimizes BB loss during quick magazine changes and ensures seamless feeding even under rapid-fire conditions.

Optimized Fitment: Includes a removable magwell and sometimes an adjustable shim set to ensure compatibility and a precise fit with a wide variety of Hi-Capa pistol brands (including TM, WE, and SSP5) and M4 AEG magazines.

Cold Weather Performance: HPA systems are immune to the performance drops caused by low temperatures that plague standard gas systems, keeping your loadout operational year-round.

Compatibility & Technical Details

Pistol Compatibility: Generally compatible with most TM, WE, and SSP5 style Hi-Capa gas magazines.

Magazine Compatibility: Works with most airsoft M4 AEG magazines, with high-quality mags (like PTS EPM series) often recommended for high rate-of-fire (ROF) setups.

HPA Requirement: Requires a paintball air tank, a low-pressure regulator (0-140 PSI output, typically recommended not to exceed 140 PSI), and an HPA line with a Foster quick disconnect.
