Do you want to shoot with high accuracy, long range and consistently hit your opponents? Are you looking for the best-selling airsoft ammunition globally that is perfectly polished, clean and highly visible? Do you want BBs that are ideal for CQB spraying, arena domination, long-range precision shots and are also environmentally friendly? Then you’ve just found the right BIO PLA BBs for you. BLS BIO ULTIMATE HEAVY BBs are a well-established brand on the 6 mm ammunition market. This Taiwanese manufacturer produces high-quality, globally best-selling BBs suitable for all airsoft guns, including pistols, rifles, SMGs, LMGs and sniper rifles. BLS BIO ULTIMATE HEAVY BBs undergo hand-measured and extremely strict quality control. Besides dimensional accuracy, the manufacturer focuses on surface finish: polishing and smoothness are inspected to ensure maximum range and stable flight trajectory. BLS BBs offer the best price-to-performance ratio. Their measured diameter is 5.95 mm (± 0.01 mm), which means you can safely use them in tightbore barrels down to 6.01 mm and even in high-speed builds pushing 25+ BB/s. BIO BBs are made from PLA-based biodegradable polymer (Polylactic Acid), which decomposes much faster in nature. Some fields and arenas require BIO BBs exclusively.
