Why Choose .40g Airsoft BBs?

At 0.40 grams, these BBs offer the highest level of stability commonly used in airsoft. The increased mass dramatically reduces wind drift, improves hop-up consistency, and maintains energy over longer distances. This results in a flatter, more predictable trajectory and tighter groupings—especially important for single-shot and semi-auto precision platforms.

These BBs are ideal for:

• Bolt-action sniper rifles

• High-powered DMR builds

• HPA and upgraded AEG platforms tuned for heavy ammunition

If your rifle is built to handle heavyweight BBs, .40g ammunition allows you to fully exploit its precision potential.

Precision Manufacturing & Tight Tolerances

HK Army Hostile BIO BBs are produced under strict quality control standards to ensure consistent diameter, weight, and surface finish. Each BB features a highly polished, seamless exterior, reducing friction and minimizing the risk of feeding issues in tight-bore barrels.

This precision manufacturing makes them safe and reliable for use in high-end hop-up systems and inner barrels, where inconsistencies in ammunition can significantly impact accuracy and performance.

Biodegradable & Field Legal

Designed with outdoor play in mind, HK Army Hostile BIO .40g BBs meet the requirements of fields that mandate biodegradable ammunition. The BIO formulation allows the BBs to naturally break down over time, helping reduce environmental impact without sacrificing reliability or accuracy.

This makes them an excellent choice for:

• Outdoor airsoft fields

• Milsim and scenario events

• Long-duration games where eco-compliance is required

You get top-tier performance while staying environmentally responsible.

White Finish for Easy Shot Tracking

The white color of these BBs provides excellent visibility in flight, allowing players to track shots and fine-tune hop-up settings with ease. Visual tracking is especially valuable for snipers and DMR users who rely on precision adjustments and feedback to maintain consistent accuracy during gameplay.

Ideal Applications & Compatibility

Recommended for:

• Sniper rifles and DMRs

• HPA systems and tuned AEGs

• Tight-bore inner barrels

• Precision hop-up units

Not recommended for:

• Stock or low-powered AEGs

Because of their weight, .40g BBs should be paired with platforms capable of generating sufficient energy and hop to achieve optimal performance.
