      Warning<\/h5>\n
        \n
      • Some manufacturers\u2019 springs are\u00a0significantly overrated<\/strong>\u00a0(e.g., an M130 spring may perform like M140\u2013150), which may exceed the declared gearbox strength.\u00a0We recommend using only the included Specna Arms springs<\/strong>. With other brands,\u00a0an M120 spring<\/strong>\u00a0is generally the safe choice.<\/li>\n
      • When installing springs with\u00a0progressive (irregular) coils<\/strong>, ensure the\u00a0tighter coil end is placed on the spring guide<\/strong>\u00a0facing outward from the gearbox.<\/li>\n
      • Never store the rifle with a connected battery.<\/strong><\/li>\n
      • Never store the rifle with pre-cocking enabled.<\/strong>\u00a0Always release the piston forward before storage to avoid spring damage.<\/li>\n<\/ul>\n
