Consistent Accuracy You Can Trust

The .28g weight class is a favorite among experienced airsoft players for its versatility. It offers improved wind resistance over lighter BBs while maintaining excellent velocity and responsiveness. HK Army Hostile BIO BBs are carefully balanced for even weight distribution, ensuring consistent hop-up engagement and stable flight from the muzzle to the target.

Thanks to their polished, seamless exterior, these BBs feed smoothly through high-capacity magazines, mid-caps, and gas magazines alike. The result is fewer misfeeds, reduced barrel friction, and improved shot-to-shot consistency—especially critical during sustained outdoor engagements.

Built Clean for Your Barrel & Your Field

Poor-quality BBs can leave behind residue, debris, or imperfections that negatively impact accuracy and internal components. Hostile BIO BBs are manufactured with a clean, polished finish that minimizes friction and eliminates barrel fouling. This not only preserves your inner barrel but also ensures consistent FPS and accuracy over extended play sessions.

Equally important, the biodegradable construction allows these BBs to naturally break down over time, making them ideal for outdoor fields with environmental restrictions. You get competitive performance without leaving a lasting footprint behind.
