The Specna Arms ONE series is renowned for combining high-quality with precision when it comes to airsoft ammunition. This range of BBs is specifically designed to offer professional performance at an affordable price. Crafted to a glossy finish and featuring a special layer to reduce friction, these BBs cooperate wonderfully with Hop-Up buckings and have a perfectly round shape. Not only that, but their core is free from air bubbles and the weight difference between individual BBs is set to a maximum of 0.01g, affording stable and consistent shots every time. The ONE BBs have a diameter of 5.95mm (+/-0.005mm), and promise to work in any type of barrel - from standard to precision.
