Product Overview
Designed for demanding airsoft environments, the AirTac Hi-Capa to M4 HPA adapter replaces traditional gas magazines with a high-efficiency HPA feeding system. This eliminates cooldown issues, ensuring stable FPS, consistent shot-to-shot accuracy, and dependable performance throughout the game.
The injection-moulded polymer housing provides a secure and precise fit, while the built-in BB-retention system ensures smooth feeding even during rapid firing and reloads. Using standard M4 AEG magazines significantly increases ammo capacity, reducing reload frequency and keeping you in the action longer.
Ideal for competitive play and extended skirmishes, this adapter delivers year-round reliability, even in cold weather where gas systems struggle. Supplied with all required mounting hardware, it offers easy installation and professional-grade performance.
