More Reasons to Love the Rapax RMS 3+J Upgrade Spring

• No More Twang:
  Eliminate the annoying “twang” sound that often accompanies standard springs. The Rapax RMS 3+J Upgrade Spring helps reduce or eliminate this noise for a stealthier experience in the field. Suggestion: always use grease on a spring guide and on the spring when installing it.
• Beginner-Friendly Installation:
  Thanks to its relatively short design, the Rapax RMS 3+J is easy to install, even for newcomers to airsoft sniper upgrades. This makes it an ideal option for both new and experienced players.
• Designed for Heavy BBs:
  The spring’s performance is optimized for heavy BBs (not 0.2g BBs). Adjust your hop-up for the best flight path before measuring FPS or Joules to ensure your shots are perfectly tuned.

Important Notes:

• If you’re using a Gspec airsoft spring gun (with a shorter 300mm barrel), you may need a stronger spring to achieve the same FPS/Joule output as longer-barreled models.
• Always measure Joules with heavy BBs for accurate results.
