Hi-Capa M4 Competition Adapter (DIY) — Carbon Fiber

Flared M4 Magwell DIY Adapter for Hi-Capa

The TAPP Hi-Capa M4 Competition Adapter (DIY) converts your Hi-Capa to accept M4 AEG magazines and adds a flared magwell for faster, more reliable reloads. This budget-friendly DIY kit uses your existing gas magazine for assembly and is 3D printed in Carbon Fiber (Nylon PA12 with the option of upgrading to PA11 Carbon Fiber composite) to deliver improved stiffness and wear resistance over standard polymer kits. While economical, the DIY approach does not match the seamless integration, fitment, or long-term durability of our one-piece Carbon Fiber adapters—those are recommended for competitive builds and heavy use.

Key Features:

• DIY Installation: Assemble the adapter using your existing gas magazine to reduce cost and customize your setup.
• HPA Powered: Optimized for High Pressure Air systems to provide consistent and reliable operation (HPA kit not included).
• Flared M4 Magwell: Engineered for faster, more confident reloads during competition or CQB scenarios.
• Carbon Fiber Construction: 3D printed in Nylon PA12 with the option of upgrading to PA11 Carbon Fiber composite for superior strength-to-weight ratio, improved impact resistance, and dimensional stability.

What’s Included:

• DIY Kit: All necessary components for assembly using your gas magazine (magazine internals not included).

Note: Limited support is provided for DIY kits. For superior durability, seamless fit, and easier installation, we recommend the one-piece Carbon Fiber competition adapters.

Compatibility:

WE-Tech, Tokyo Marui, Armorer Works, Novritsch SSP1/SSP5, and other compatible Hi-Capa platforms—verify fitment before installation.
