If you are looking for affordable biodegradable BBs, NUPROL's RZR BBs would be a great choice! RZRs have a superb reputation for precision and tight tolerances and this version is made from a biodegradable material which means you can shoot as much as you want without worrying about cleanup afterwards.

Full description

These might come in handy...


These 0.20g 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 0.20g in weight, making them well suited to indoor gameplay where projectile speed is a priority over wind resistance and long range effectiveness. Being 5.95mm +/- 0.01mm makes them equally useful for tightbore barrel setups, guaranteeing smooth feeding with every shot. If your local site only allows Bio BBs, NUPROL's RZR BBs are a fine choice made even better thanks to this great value bulk bag!
