GSeries / AAP-01 M4 Competition Adapter (DIY) — Carbon Fiber

Flared M4 Magwell DIY Adapter for Faster Reloads

The TAPP GSeries / AAP-01 M4 Competition Adapter (DIY) converts your GSeries or AAP-01 to accept M4 AEG magazines and adds a flared magwell for quicker, 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 improve stiffness and wear resistance over plain polymer kits. For competitive or heavy-use builds, we still recommend the one-piece Carbon Fiber adapters for best fit, durability, and long-term performance.

Key Features:

• DIY Installation: Assemble the adapter using your own gas magazine for an economical conversion.
• HPA Powered: Designed for High Pressure Air setups to provide consistent, reliable operation (HPA kit not included).
• Flared M4 Magwell: Designed for faster reloads and improved ergonomics during competition or close-quarters 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, impact resistance, and dimensional stability.

What’s Included:

• DIY Kit: Components required to assemble the adapter using your gas magazine (magazine internals not included).

Note: Limited support is provided for DIY kits. One-piece Carbon Fiber competition adapters are recommended for enhanced durability, seamless fit, and easier installation.

Compatibility:

Elite Force, UMAREX GSeries, AAP-01, and other compatible GBB pistols—verify fitment before installation.
