T4E 68 Performance RBI Balls – 10 pcs

T4E Performance RBI .68 – The Power of Steel in a Rubber Shell

T4E Performance RBI (Rubber Ball Iron) projectiles are the highest-performance ammunition for .68 caliber (17.3 mm) weapons. Unlike standard rubber balls, these projectiles contain an internal steel core, which radically increases their total weight to an impressive 7.67 g. This high material density allows the projectile to better maintain speed and stability even over longer distances.

The RBI design ensures that the outer rubber layer provides optimal rotation and ballistics in the barrel, while the steel core adds the necessary inertia and destructive impact at the target. They are fully compatible with all Umarex T4E series weapons in .68 caliber, such as the HDX 68 shotgun or HDR 68 revolvers. Due to their hardness and energy, they are ideal for tactical training focused on barrier penetration or specific defensive purposes.

Frequently Asked Questions (FAQ):

1. Are these balls safe for my gun's barrel?
Yes. The steel core is fully encapsulated in the rubber shell. Steel never comes into direct contact with the barrel, preventing scratches or excessive wear.

2. What is the main difference between RBI and standard Rubber Balls?
The main difference is weight and hardness. A standard rubber ball weighs about 3 g, while the RBI weighs 7.67 g. This means the RBI has much higher impact energy (Joules) and penetrates obstacles much better.

3. Can these balls be reused?
Due to their construction and steel core, the balls do not deform as easily as pure rubber ones. If they are not visibly damaged or dirty, they can be used again after cleaning, but for maximum accuracy, we always recommend new balls.
