Why Choose HPA .28g Biodegradable BBs?

For airsoft players, BB quality directly impacts accuracy, consistency, and reliability. Low-grade BBs can shatter, cause jams, or degrade performance, but HPA’s lab-tested biodegradable BBs solve these issues:

• Improved Accuracy: Tight tolerances and seamless construction mean straighter trajectories and more consistent grouping.

• Reliable Feeding: Whether you’re running a high-speed AEG, GBB pistol, or precision sniper rifle, these BBs feed smoothly and consistently.

• Eco-Friendly Gameplay: Fully biodegradable under EN13432 standards, ensuring compliance with most outdoor and environmentally conscious fields.

• Stronger & Safer: Less prone to chipping or shattering compared to cheaper bio BBs, protecting both your rifle and your investment.

The 0.28g weight is especially well-suited for upgraded AEGs, HPA systems, and gas blowback rifles, where a slightly heavier BB provides better stability in flight, reduced wind drift, and improved accuracy at range.
