BLS 0.40g Ultimate Heavy BBS 1kg Bag – Ivory

BLS Ultimate Heavy BBS represent a step up in quality for serious players. At 0.40g per round, these are heavyweight projectiles designed to work with properly tuned hop-up systems and elevated FPS setups. The 1kg bag contains roughly 1,000 rounds of consistent, polished ammunition.

Key Features

• Ultra-tight tolerance – 5.95mm±0.01mm diameter for minimal wobble and enhanced accuracy
• Heavyweight profile – 0.40g mass suits upgraded AEGs and sniper platforms
• 1kg pack – approximately 1,000 rounds; economical for regular skirmishers
• Ivory colour – high-visibility rounds make spent case auditing easier downrange
• Polish finish – smooth surface reduces friction and hop-up drag

Real-World Use Cases

Ideal for players running upgraded gearboxes, M140+ springs, or tuned DSG builds. The 0.40g weight maintains velocity over distance whilst reducing side-drift in outdoor skirmishes. Heavy-duty hop-up bucking systems (such as Prometheus or Lambda) can reliably stabilise these rounds, making them excellent for semi-auto precision work. Milsim teams fielding bolt-action or spring sniper platforms also benefit from the flatter trajectory.

Compatibility & Upgrades

UK Legal & Site Notes

Heavy BBs remain unrestricted under UK airsoft law, but always check your local site rules before play. Many indoor CQB venues restrict BB weight; confirm 0.40g compliance with marshals beforehand. Store in a cool, dry place away from direct sunlight to preserve finish.
