Elite Force MILSIM Heavy Reserve Biodegradable BBs

These are heavy-weight 0.40g BBs, which are specifically designed for high-performance, upgraded airsoft rifles and sniper platforms. They are generally too heavy for standard, entry-level AEGs and may cause feeding issues or low velocity in stock guns.

No. These BBs are designed to remain stable under normal storage conditions and will only begin to break down when exposed to specific environmental factors like moisture, soil bacteria, and prolonged UV exposure in the field.

The 5.95mm diameter is a precision standard that minimizes the gap between the BB and your inner barrel. This tight tolerance reduces air leakage and barrel vibration, which directly improves your accuracy and consistency at long ranges.

The high-gloss, seamless finish is specifically engineered to prevent surface imperfections that cause friction. While all BBs require regular barrel maintenance, this polished surface significantly reduces the buildup of debris compared to lower-quality, matte-finish rounds.

While you can use them indoors, these BBs are optimized for outdoor field operations where their biodegradable composition is most beneficial. Because they are heavy, ensure your indoor backstop is capable of absorbing the higher kinetic energy these rounds carry.
