Umarex BB 4.5mm – Reliable ammunition for your air pistol
Umarex is a world leader in airguns, and their 4.5mm BB steel round balls are no exception. With this box of 1,500 rounds, you get ammunition specially designed to function flawlessly in magazines and barrels, so you can focus on hitting the bullseye.
The expert behind the counter recommends: Following the new rules that came into effect in February 2026, we are required to scan an ID or digital firearms licence when selling any ammunition, including airgun ammunition. When it comes to shooting itself: Always use polished steel BBs like these from Umarex. Cheap rounds with an uneven surface can cause jamming and, in the worst case, damage the magazine’s feeding mechanism.
Precision in every shot
Every single BB is polished to minimise friction in the barrel. This not only provides higher muzzle velocity, but also improved accuracy. Umarex 4.5mm BBs are the safe choice for all types of CO2 pistols, whether they have blowback or a fixed slide.
