NOVRITSCH 0.40 g BIO BBs — 555 rds

Heavy-weight 0.40 g BBs designed for precision airsoft replicas, packaged in a bottle of 555 rounds. The biodegradable formula makes them compliant with outdoor field regulations that ban conventional BBs, without sacrificing the ballistic performance required for accurate shooting at medium and long range.

The 0.40 g weight reduces wind drift and stabilises the trajectory over the demanding distances typical of sniper-role gameplay, where a lighter BB loses velocity and direction too quickly. The trade-off is the classic one for heavy BBs: you gain stability and wind resistance, but you need a replica with a sufficiently powerful spring and a tuned hop-up to impart enough backspin and kinetic energy — on standard or stock replicas, a 0.40 g BB can be underpowered and actually distort the trajectory rather than improve it.

The surface is polished to minimise the irregularities that cause unpredictable deviations in the feed channel and hop-up chamber. According to NOVRITSCH, the balance between polish level, material and weight was refined through months of field testing before reaching the current formulation. The BIO certification is formally documented, meaning the BBs break down over time rather than accumulating in the environment.

Key points

• The 0.40 g weight stabilises long-range trajectory and reduces wind sensitivity compared to standard 0.20–0.28 g BBs.
• Certified biodegradable formula: suitable for outdoor fields requiring BIO BBs, without compromising performance.
• Polished surface for consistent feeding through the magazine and hop-up channel, reducing random deviations.
• Bottle of 555 BBs: a practical field size with no unnecessary bulk.
• Developed directly by NOVRITSCH for sniping use: tolerance and finish requirements oriented towards precision airsoft shooting.
