Specna Arms CORE BB's are a cost-effective BB, designed to give excellent performance without breaking the bank. Each bag is 1kg, and manufactured with precision, which allows them to work with guns out of the box, as well as upgraded/tuned replicas with precision barrels.

Every BB in your CORE bag is manufactured at 5.95mm with a tolerance of /- 0.005mm, ensuring compatibility even with 6.01mm tightbore barrels. Best of all, such small deviations are not limited to size, but also weight - the difference between every pellet will not exceed 0.01g, improving shot-to-shot consistency.

Specna Arms have concentrated on the areas that matter most to the gamer - ensuring perfect shape for the BB, which combined with their meticulous quality assurance, gives you the peace of mind that you will be problem-free for feeding (in all sorts of magazines). 

These BB's are 0.25g - the standard choice for the more discerning airsofter
