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.
