Airsoft BB BLS BIO 0.25g/4000

BLS BIO 0.25g – Precision Biodegradable Airsoft BBs, 4000 Rounds

BLS BIO 0.25g airsoft BBs are designed for players who demand consistent dimensions, reliable feeding and predictable flight performance. Manufactured by Taiwanese airsoft ammunition specialist BLS, these biodegradable BBs combine precision manufacturing with PLA-based material.

The 0.25g weight offers a practical balance of velocity, flight stability and range, making these BBs a popular choice for standard AEG rifles, outdoor airsoft games and CQB environments.

Precision Diameter – 5.95 mm ± 0.01 mm

BLS BBs feature a carefully controlled 5.95 mm diameter with a tolerance of ±0.01 mm.

Their consistent dimensions and polished surface support smooth feeding, reliable hop-up contact and repeatable performance.

They are suitable for compatible precision inner barrels, including 6.01 mm tightbore barrels, provided the airsoft gun is properly maintained.

Biodegradable BIO PLA Material

These BBs are made from BIO PLA (polylactic acid), a biodegradable polymer derived from renewable raw materials.

Compared with conventional plastic ammunition, PLA-based BBs can biodegrade under suitable environmental conditions. They are particularly useful for outdoor airsoft fields and events requiring biodegradable ammunition.

Actual decomposition rates depend on environmental conditions such as temperature, moisture and biological activity.

4000 BBs in a Resealable 1 kg Bag

Each package contains 4000 BBs with a total ammunition weight of 1 kg.

The durable resealable bag allows convenient transportation, refilling and storage while helping protect the BBs from dust, dirt and moisture.
