If you are looking for heavy-weight biodegradable BBs, NUPROL's RZR BBs would be a great choice!

Full description

These might come in handy...


These 0.36g BBs are constructed from a special biodegradable polymer and measure 5.95mm in diameter with a tolerance of +/- 0.01mm, making them a great choice for improved accuracy and smooth, consistent feeding compared to cheaper alternatives. You are what you eat, and the same is true for your Airsoft gun. To get the most out of features such as adjustable HOP-up units and tightbore inner barrels, high quality ammo is an absolute must!

These BBs are approximately 0.36g in weight, making them well suited to use with sniper rifles, DMRs and other high FPS or upgraded setups. The extra weight will reduce your projectile velocity but means your BBs are less affected by the wind and can cut through foliage more effectively without losing too much energy. Being 5.95mm +/- 0.01mm guarantees smooth feeding in setups with a tightbore inner barrel and the tight tolerances help your rifle be as consistent, and thus, as accurate as possible. If your local site is a woodland and they only allow Bio BBs, these are perfect for handling any long-range threat!
