The diameter of a BB is 5.95 mm (+/- 0.005mm) and the difference in weight among BBs does not exceed 0.01 g. As a result, Specna Arms BBs work very well both with standard internal barrels as well as with precision barrels present in tuned replicas.
At the final stage of production, high-polish is carefully applied to every BB made by Specna Arms. Thanks to a full control over the production process, the manufacturer receives BBs with perfect shape. This in turn guarantees seamless BB feeding by all types of magazines as well as a stable spin provided by the Hop-Up system.
