Swiss Arms Bio BB's (0.20g) (5,000 Rounds)

King Arms BB's are easily one of the best BB's on the market - they are extremely high quality, precision made, and polished for a smooth finish to work with even 6.01mm tightbore barrels.

Their series of biodegradable BB's is certainly no exception. They are seamless, well-polished, and extremely consistent. Unlike many other brands which suffer from poor centre of gravity, the King Arms Bio-BB's are evenly weighted ensuring you get the most out of each shot!

This particular bag is the industry standard of 0.20g BB's, and comes in 1kg pacakges. You get 5,000 precision rounds in each bag, and the bag itself is resealable
