The Specna Arms EDGE ULTRA™ BIO 0.40g BBs are high-quality precision airsoft BBs designed for demanding airsoft players who require maximum consistency, accuracy and stable ballistic performance.
This BIO version is made from biodegradable material, allowing the BBs to naturally decompose over time. This makes them ideal for use on airsoft fields where bio BBs are required.
Each BB has a diameter of 5.95 mm (±0.01 mm), ensuring a perfect fit in precision inner barrels. The weight difference between individual BBs does not exceed 0.01 g, providing excellent consistency and repeatable ballistic performance.
During production, the BBs undergo strict quality control at every stage of the manufacturing process. Each BB is carefully polished to a high-gloss finish, which improves flight stability and minimizes surface imperfections.
EDGE ULTRA™ BBs are also coated with a special friction-reducing layer, ensuring smooth interaction with precision barrels and excellent results when used with Hop-Up buckings.
Thanks to the perfectly balanced center of gravity and the absence of internal air pockets, these BBs deliver reliable and consistent performance even in high-performance airsoft replicas such as DMR or sniper platforms.
