The Nimrod BIO Professional Performance BBs are a top-of-the-line product specifically designed for players seeking the highest possible shot consistency, outstanding quality and maximum accuracy.

The Professional Series of BBs offer superior performance and are ideal for high-end tuned replicas where even the slightest inconsistency in the BB structure will affect accuracy and dispersion. Measuring 5.95mm +/- 0.01mm and featuring a highly polished finish, the BBs offer predictable trajectory and repeatable performance with every shot.

Even at high firing rates of up to 50 shots per second, these BBs deliver reliably and consistently.

In addition, they are biodegradable – a common requirement for skirmishes and airsoft arenas.
