Delta Armory 0.40g BIO EAGLE BBs – Biodegradable 1kg White

Delta Armory 0.40g BIO EAGLE BBs represent a responsible choice for airsoft players who value both performance and environmental impact. These biodegradable rounds are engineered to provide reliable consistency across all AEG platforms, ensuring accuracy downrange without compromising on trajectory or energy retention.

Key Features

• Biodegradable PLA polymer construction – breaks down naturally in outdoor environments
• 0.40g weight – ideal for longer-range engagement and improved accuracy
• White finish – high visibility for recovery and field management
• 1kg bag capacity – approximately 4,500 rounds per bag
• Consistent quality – uniform weight and diameter for reliable hop-up performance

Real-World Use Cases

These BBs excel in outdoor woodland skirmishes, milsim events, and outdoor CQB scenarios where environmental considerations matter. The 0.40g weight suits bolt-action sniper rifles, upgraded AEG platforms, and higher-power platforms where heavier rounds stabilise better. Many UK airsoft sites now encourage or require biodegradable ammunition, making this an essential upgrade for regular players.

Technical Specifications

• Weight: 0.40g per round
• Material: Biodegradable PLA polymer
• Colour: White
• Quantity: Approximately 4,500 rounds per 1kg bag
• Packaging: 1kg resealable bag

Compatibility & Upgrades

These rounds work with all standard airsoft AEG gearboxes, gas blowback pistols, and sniper rifles with standard 6mm bore. Heavier 0.40g BBs benefit from upgraded hop-up units and tighter barrels; they’ll perform adequately in stock platforms but truly shine in tuned builds. Always check your hop-up is clean and properly adjusted before use to avoid feeding issues.

UK Legal & Site Notes

Biodegradable BBs comply with UK airsoft regulations and are actively welcomed at most organised sites. Many woodland venues specifically request eco-friendly ammunition to minimise environmental impact. Always verify your chosen site’s BB policy before attending, as some indoor CQB venues may have specific ammunition requirements.
