The Impact Burst Airsoft Impact BB Grenade is a spring-powered airsoft BB grenade designed primarily for CQB and use on hard surfaces.
This remix modifies the original design with an improved internal spring setup and activation mechanism. It adds dedicated spring room and a spring guide for standard AEG springs, making it possible to use commonly available AEG springs instead of needing a specific spring.
The activation rotation has also been increased from 5° to 10°. This provides a larger activation movement and helps reduce the risk of the grenade accidentally going off while being handled.
The grenade requires a reasonably firm throw to reliably activate, so it is best suited for hard surfaces where the impact is more consistent.
