KWA MP9 M4 Competition Adapter
The KWA MP9 is a small and agile submachine gun (SMG), highly regarded for its rapid fire rate and effectiveness in tight spaces. The TAPP KWA MP9 M4 Competition Adapter elevates this platform by allowing the use of M4 AEG magazines and incorporating a flared magwell for faster reloads. Designed and manufactured in the USA, this pre-built, plug-and-play adapter is perfect for competitive players who demand quick, seamless reloads under pressure. Additionally, it is compatible with the Vorsk Airsoft VMP-1, offering flexibility across different platforms.
Key Features:
– M4 Magazine Compatibility: Adapt your KWA MP9 to use M4 AEG magazines, increasing your capacity and making reloads faster and more intuitive, ideal for competitive play.
– Flared Magwell: The M4 Competition magwell is specifically designed to enable quicker and smoother magazine changes, giving you a crucial advantage in high-speed engagements.
– HPA Powered: Calibrated for 150 max, recommended PSI: 150 max, recommended 120, this adapter delivers consistent and reliable performance, keeping your SMG ready for action in any scenario (HPA kit available separately at tappairsoft. com/hpa).
– Optimized Reload Efficiency: The combination of the flared magwell and M4 magazines ensures a seamless reloading experience, critical for maintaining your edge in competition.
– One-Piece Magazine Adapter Design: Specifically engineered to enhance the overall functionality and reliability of your MP9, providing a smooth and efficient reloading process.
– Durable Construction: Built from lightweight, durable SLS Nylon PA12 with the option of upgrading to PA11 Carbon Fiber material, this adapter is crafted to withstand the demands of intense airsoft action.

CARBON FIBER. CARBON FIBER.CARBON FIBER.
Strength you can feel. Weight you barely notice. Precision that defines performance. Matte black, rigid, and ready — engineered for those who demand more than plastic.
Unmatched Strength and Rigidity
• Up to 38% Higher Tensile Strength – 69 MPa vs. 50 MPa for Nylon 12, giving parts more load-bearing capability. • Nearly 3× Stiffer – With a tensile modulus of 5.3 GPa (vs. 1.9 GPa), PA11 CF parts hold their shape under pressure and stress. • Over 65% Greater Flexural Strength – 110 MPa vs. 66 MPa for Nylon 12 means stronger parts that won’t bend or deform.
Superior Heat and Environmental Resistance
• Designed for high-temperature applications where Nylon 12 softens or degrades. • Carbon fiber reinforcement improves thermal stability and lowers thermal expansion for precision even under heat. • Naturally resistant to moisture and UV exposure, ideal for rigorous outdoor use.
Professional Finish and Lightweight Design
• Carbon fiber infusion produces a sleek matte black surface — functional and aesthetic right off the printer. • Delivers metal-like strength at a fraction of the weight, enabling lighter, more efficient assemblies.
Designed for High-Pressure HPA systems
• Lightweight carbon fiber composite reduces load without sacrificing strength or rigidity. • Tested for durability across extreme temperature and humidity conditions to ensure reliable field performance.
Rigid Carbon Fiber Structure
• Low expansion under heat preserves airseal integrity during rapid-fire or sustained full-auto use. • Machined precision surfaces ensure smooth magazine insertion and consistent alignment with feed paths.
Custom Cerakote & Precision Coatings
