Overview

Bring your Airsoft games to the next level with this 100% 3D-printed Impact Grenade. It utilizes standard 8-shot ring caps (fulminantes) to trigger a loud, satisfying bang upon impact. Designed with safety and simplicity in mind, it requires no complex hardware—just a simple rubber band to hold it together.

Features & Safety Design

• Spark Shield / Anti-Fire Barrier: The bottom hemisphere features an extended outer rim that acts as a physical barrier. This contains the sparks inside the core and prevents them from escaping, making it significantly safer to use on the field.
• Smart Rubber Band Groove: The top and bottom hemispheres include a dedicated recessed track. Once assembled, the rubber band stays locked in place and won't slip off.
• Easy Reload: Quick and simple mechanism to swap the ring cap between rounds.
