Recommendations & practical tips

• Keep your magazines clean
  When crawling or playing in dusty environments, use pouches with flaps. Sand in your magazine will be carried straight into the hop-up chamber and barrel, degrading accuracy and damaging the bucking and barrel.
  
  
• Don’t reuse BBs from the ground
  Even tiny dust particles act like sandpaper inside your hop-up and barrel.
  
  
• Regular inner barrel maintenance
  After each game, clean the inner barrel with a cleaning rod and a dry microfiber cloth. Avoid oils – the barrel must stay dry and degreased for the hop-up to work properly. You can use isopropyl alcohol for degreasing. Also see our guide How to properly clean an airsoft barrel.
  
  
• Watch your speedloaders
  Dirt often enters your replica through a dirty speedloader. Keep them clean just like your magazines.
  
  
• Material degradation
  BIO/PLA BBs absorb moisture. If you store them in a magazine or open packaging for weeks, they may swell or change surface properties, causing jams and serious replica damage. Dispose of deformed BBs immediately.
  
  
• Final tip
  Don’t hoard BBs for years. Buy fresh stock before events and use opened bags quickly. Store them in the original sealed packaging with a silica gel packet. A cheap dirty BB can easily damage a premium barrel. Professional snipers even degrease their BBs before every game. If unsure which BB type to choose, read our guide How to choose the right airsoft BBs.
