BLS TRACER Airsoft Pellets 0.25g, 4000 BBs (Bag) - Green

BLS TRACER Airsoft BBs

Do you want to shoot accurately and far, and most importantly hit your opponents with laser-like streaks? Are you looking for the world’s best-selling ammo for airsoft guns, perfectly smooth, clean and highly visible? Do you want tracer BBs that are made for spraying, dominating CQB arenas and performing precise long-range shots? Then these are the right BBs for you. BLS TRACER BBs are one of the most trusted names in high-quality 6 mm ammo. This Taiwanese manufacturer delivers globally best-selling BBs for all types of airsoft guns — pistols, rifles, SMGs, LMGs and sniper rifles. BLS TRACER BBs undergo hand-measured and extremely strict quality control. Besides dimensional accuracy, BLS also focuses on surface quality — polishing and smoothness are carefully checked to achieve 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), making them safe for use even in tightbore barrels (6.01 mm) and high-RoF setups (25+ BBs/s). To charge the BBs, a tracer unit is required — either a tracer suppressor, a tracer magazine or a hop-up chamber with a built-in tracer module.

Recommendations & Practical Tips

• Magazines as a vault
  When crawling or playing in dusty environments, use pouches with flaps. Sand inside your magazine will be pushed straight into the hop-up and barrel, instantly ruining accuracy and damaging the bucking and barrel.
  
  
• Do not reuse dropped BBs
  If BBs fall on the ground or stay exposed in a dusty environment, do not use them again. Even microscopic dust acts like sandpaper on your hop-up and barrel.
  
  
• Regular inner barrel cleaning
  After every game, clean your inner barrel with a cleaning rod and a piece of dry microfiber cloth. Avoid oils — the barrel must be dry for proper hop-up function. For degreasing, you may use isopropyl alcohol. See our guide How to clean your airsoft barrel.
  
  
• Watch your speedloaders
  Dirt often enters the gun through a dirty speedloader. Keep them clean.
  
  
• Material degradation
  BBs (especially BIO / PLA) absorb moisture over time. When stored opened for weeks, they may swell or change surface properties, causing jams and severe damage. Dispose of any deformed BBs immediately.
  
  
• Final advice
  Don’t stockpile BBs for years. Buy before events, use them quickly, store them in original packaging with silica gel. Even a premium barrel can be ruined by dirty or degraded BBs. Professional snipers even degrease BBs before every game. If unsure which BBs to choose, read our article How to choose airsoft BBs.
