RBI Rubber Balls Impact T4E – Training ammunition for T4E markers

The RBI Rubber Balls Impact are specialised training projectiles designed for T4E marker systems. These 12.7mm calibre rubber balls weigh 2.91 grain and feature a metal core encased in rubber, providing controlled impact feedback during force-on-force training scenarios.

Construction and materials

Each projectile combines a metal core with a rubber outer layer, creating a dual-density design. The 12.7mm diameter ensures precise fit in .50 calibre T4E markers. At 2.91 grain, these projectiles maintain consistent mass distribution for reliable ballistics. The black rubber exterior absorbs impact energy while the internal metal core provides sufficient weight for realistic trajectory and feedback.

Application and use

These training rounds are designed for force-on-force exercises with T4E training markers. Security personnel, law enforcement trainers, and tactical instructors use them to simulate real-world scenarios safely. The rubber construction allows for direct human target engagement during training exercises while minimising injury risk.

Integration and compatibility

The projectiles are engineered specifically for 12.7mm/.50 calibre T4E marker platforms. They function reliably in air rifle systems designed for training ammunition. Each container includes 100 rounds, providing sufficient quantity for extended training sessions.

Maintenance and lifecycle

The rubber construction allows for potential projectile recovery and reuse after training exercises. Regular inspection for deformation or damage ensures consistent performance. Storage in dry conditions preserves the rubber material properties and maintains projectile integrity.
