Umarex T4E RB Steel balls Cal.50 – 2.6 g | pack of 10 | hard rubber with steel filings

Umarex T4E RB Steel .50 – Maximum power for your weapon

Umarex T4E RB Steel projectiles represent the technological pinnacle in ammunition for T4E (Training for Engagement) training and defense systems. Each ball is made from a special blend of hard rubber into which steel filings are evenly mixed. This unique combination increases the total weight of the ball to 2.6 g, which dramatically changes its ballistic properties. This weapon against targets excels in flight stability and, above all, destructive effect at the point of impact, where the steel core ensures minimal deformation and maximum energy transfer.

RB Steel ammunition is designed for realistic shooting practice and active self-defense. Due to its high hardness and weight, this ammunition is unsuitable for standard paintball games against live targets without professional protection, as there is a risk of serious injury. They are compatible with all Umarex T4E series weapons of .50 caliber, such as HDR 50 revolvers or HDP 50 pistols. The 10-piece pack is ideal for testing ballistic properties or as an emergency supply for defensive purposes.

Frequently Asked Questions (FAQ):

1. Are these balls reusable?
Technically yes, if they are not damaged or dirty. However, for safety reasons and to maintain the accuracy of your weapon, we recommend always using new balls for defensive purposes.

2. Can I use these balls on a paintball field?
Usually not. Due to the steel admixture, they are too hard and heavy for regular sports games. Always check with the arena operator beforehand.

3. Will the steel filings damage my weapon's barrel?
No, the steel filings are cast directly into the rubber compound, so there is no direct metal-to-barrel contact. Your weapon is safe.


Safety Warning:

Always use certified eye protection when shooting. This ammunition has high reflectivity from hard surfaces. Never aim at people or animals unless it is an extreme emergency in self-defense. Keep out of reach of children.
