- Durable .50 caliber rubber rounds for training and self-defense—deliver strong, non-penetrating impact with exceptional accuracy and reliable performance in any situation.

Umarex T4E Practice RUB .50 Rubber Balls are durable, multi-purpose rounds designed for .50 caliber RAM markers. Built for self-defense, recreational use, and intensive tactical training, they perform reliably in both civilian settings and professional law enforcement drills.
High Stopping Power – Constructed from dense, high-impact rubber, these rounds deliver strong kinetic energy upon impact. While non-penetrating, they generate significant pain and knock-down force, making them a highly effective option for non-lethal self-defense.
Precision Shape and Surface – Each ball features a perfectly spherical design and smooth finish, ensuring exceptional accuracy and smooth operation within the marker. Their consistent shape reduces the risk of jams and guarantees stable flight, which is especially critical during rapid, high-stress shooting scenarios or team-based exercises.
Versatile Application – The Umarex T4E RUB .50 rounds are ideal for shooting drills, tactical simulations, force-on-force games, and daily self-defense use. Their impact force and rugged design allow them to perform well in a variety of environments and weather conditions.
Universal Compatibility – Compatible with a wide range of .50 caliber RAM markers, including popular models such as the Umarex HDR 50, HDS 50, HDP 50, and training markers from Vesta Defense. Their broad compatibility makes them a top choice for shooting enthusiasts and tactical instructors alike.
