BLS is the best-selling airsoft BB brand in the world, and not by coincidence. Their BBs are manufactured using fully automated technology and undergo precise grinding and polishing, ensuring maximum roundness, minimal deviations, and excellent compatibility with precision barrels and sensitive feeding systems. Thanks to this, BLS has earned the trust of airsoft players at all levels, from beginners to professionals and competitive teams.
The BLS brand (Lien Sheng Plastic Industry Co., Ltd.) was founded in 1991 and originally focused on precision grinding for the jewelry industry. With the growing popularity of airsoft, the company redirected its production capacity in 1996 to the manufacture of airsoft BBs. Today, it ranks among the absolute leaders in airsoft ammunition, offering both standard plastic variants and biodegradable BIO BBs.
Hundreds of tons of BBs are produced every month, in various weights ranging from 0.12 g up to 0.50 g. The selection includes standard BBs for AEG replicas, precision ammo for HPA systems and sniper rifles, as well as BBs for gas replicas or manual guns. All BBs undergo quality control, including manual measurements, ensuring consistent output quality in every batch. The result is BB ammunition that does not jam replicas, maintains accuracy, and does not foul the barrel.
