Umarex BB 4.5mm – Reliable ammunition for your air pistol
Umarex is the world leader in airguns, and their 4.5mm BB steel rounds are no exception. With this box of 1500, you get ammunition that is specifically designed to function flawlessly in magazines and barrels, so you can focus on hitting the target.
The expert behind the counter advises: According to the new rules that came into effect in February 2026, we are required to scan ID or digital firearms cards when selling all ammunition, including airguns. As for the actual shooting: Always use polished steel BBs like these from Umarex. Cheap bullets with an uneven surface can cause jamming and, in the worst case, destroy the magazine's feeding mechanism.
Precision in every bullet
Each bullet is polished to minimize friction in the barrel. This not only provides higher muzzle velocity, but also better accuracy. Umarex 4.5mm BB is the safe choice for all types of CO2 pistols, whether they have blowback or fixed slide.
