The diameter of Specna Arms CORE BBs is 5.95 mm (+/- 0.005 mm) and the difference in weight between BBs does not exceed 0.01 g, which makes them ideal for replicas with a stock internal barrel as well as tuned replicas equipped with precision barrels.
A very good focus of shots is provided by the ideal shape of each Specna Arms CORE BB. Meticulous quality assurance and high-gloss polish guarantee problem-free feeding of BBs from all sorts of magazines and a stable spin of the BB by the Hop-Up system.
