Delta Armory 0.40g BIO EAGLE BBs – Biodegradable White

Delta Armory 0.40g BIO EAGLE BBs are premium biodegradable airsoft ammunition designed for players who demand both performance and environmental accountability. Whether you’re a regular skirmisher, milsim operator, or tournament competitor, these 0.40g rounds offer the consistency and accuracy expected from quality ammunition—without the ecological footprint of standard plastic BBs.

Key Features

• 0.40g weight – precise ballistics and improved range for heavier platforms
• Biodegradable polymer construction – compliant with most UK airsoft sites
• White finish – clean appearance and easy visibility on range
• High sphericity – superior feeding and accuracy across gearboxes
• 5kg bulk package – excellent value for regular players

Real-World Use Cases

These BBs are ideal for players running upgraded AEGs, sniper platforms, or DMR builds where 0.40g ammo maximises consistency. Their biodegradable composition makes them the go-to choice for outdoor sites with strict environmental policies, woodland skirmishes, and milsim events. If you’re rotating between multiple sites or building a green loadout, a 5kg supply ensures you’re never caught short.

Technical Specifications

• Weight: 0.40g per round
• Material: Biodegradable polymer
• Colour: White
• Package size: 5kg
• Sphericity: High-grade polished

Compatibility & Upgrades

These 0.40g rounds are compatible with all standard airsoft platforms—AEGs, GBBs, springers, and HPA systems. Slightly heavier than 0.30g ammunition, they perform best in upgraded gearboxes with strong springs and full-cylinder builds, delivering tighter groupings and extended effective range. Feed them through your preferred magazine type without concern; high sphericity ensures consistent loading.

UK Legal & Site Notes

Biodegradable BBs are widely accepted at UK outdoor sites and increasingly required at woodland locations. Always confirm your chosen site’s ammunition policy before arrival. These rounds comply with standard airsoft ammunition specifications and pose no additional legal considerations beyond regular airsoft use.
