Matrix STG44 AEG Shell Adapter Details
Matrix STG44 AEG Shell Adapter
Add immersive realism to your STG44 with airsoft shotgun shell compatibility—now 3D printed in Nylon PA12 with the option of upgrading to PA11 Carbon Fiber for superior strength, durability, and long-term performance. Designed for reliability, this plug-and-play adapter features a spring-loaded plunger for smooth, satisfying shell ejection and consistent feeding.
Key Features:
– Shotgun Shell Compatibility: Runs airsoft shotgun shells for a cinematic, uniquely engaging reload experience.
– Ejecting Shell Design: Spring-loaded plunger ejects shells on mag release for smooth, reliable operation.
– Nylon PA12 with the option of upgrading to PA11 Carbon Fiber Construction: Carbon fiber–reinforced PA11 delivers high rigidity, impact resistance, heat stability, and longevity—lightweight without sacrificing strength or precision.
What’s Included:
– Fully Assembled Shell Adapter: Drop-in ready—no setup or extra modifications required.
Compatibility: Matrix STG44 AEG

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
