Loading & Care Tips

• Spring Break-In: Mid-caps perform best when broken in gradually. Fill the magazine to half capacity for your first 2–3 skirmish loads before pushing it to the full 120 rounds to let the internal spring settle.
• Use Quality BBs: Pair with high-grade, polished 0.20g–0.28g BBs to prevent inner channel jams during high rate-of-fire bursts.
• Decompress After Play: Always empty your mid-caps at the end of the day. Storing magazines loaded under tension weakens the spring over time, reducing feeding reliability.
