Airtac KWA / ASG MAC11 to MP5 HPA Adapter - Non-Prebuilt

This MP5 HPA adapter is designed for KWA/ASG MAC11 platforms, delivering a lightweight, economical alternative to gas mags with a compact, streamlined profile. It shortens the magazine form for a clean look and reliable feeding, while maintaining a strong air seal. Note: a donor magazine is required for the exhaust valve and gas router.

• Magazine compatibility : Compatible with all CYMA MP5 Mid Caps (65 round metal, 120/130 round metal, Straight, Novritsch Straight, Bullet Window). MP5 magazines are not included; use your own CYMA MP5 mid caps for feed through the adapter.
• Lightweight, compact design : Shortened magazine format reduces weight and bulk, giving a sleeker silhouette that mirrors the MAC11 grip.
• NS2 feeding improvements : Includes feed lips engineered to address common feeding issues when using AEG magazines with NS2 MAC11 setups.
• CNC-machined valve insert : Precision-made insert delivers a consistent, long-lasting air seal for stable performance.
• Replaceable feed tube : Easy-to-service feed tube allows quick maintenance and future upgrades.
• Gas routing and exhaust readiness : Built to work with a donor mag for exhaust valve and gas router—clear path for reliable gas flow.
• US-style fitting as standard : Ready to pair with common HPA systems without additional adapters.
• BB retention mechanism : On-maga BB retention helps minimize BB loss during magazine changes.
• Aesthetic alignment : Straight magazines follow the MAC11 grip for a cohesive, professional look.
• Simple installation : Quick, user-friendly setup: remove the valve from a MAC11 magazine, fit the CNC insert, install into the adapter, lubricate the valve, then attach the feed lips and gas router from your magazine.
• Out-of-spec mag tolerance : Small rear tabs can be filed down to accommodate out-of-spec magazines, preserving a tight, reliable fit.
• In-use behavior : Expect a tight initial insertion as the system settles to a perfect seal and consistent feeding during break-in.

This adapter is ideal for MAC11 enthusiasts who want a dependable, field-ready HPA solution without the bulk and cost of traditional gas mags. By leveraging CYMA MP5 mid-cap magazines and a purpose-built CNC insert, it offers consistent air delivery, reduced BB loss, and a clean, low-profile appearance. The design prioritizes straightforward maintenance and upgrade flexibility, making it easy to swap mag types as your needs evolve—whether you’re dialing in performance for skirmishes, training drills, or more advanced HPA setups.
