The E&C 300 BB high-capacity magazine is engineered for users who need extended capacity and dependable feeding on M4 / AR-15 style airsoft replicas. The durable nylon body keeps weight low while offering structural strength; the lower feed assembly features a reinforced feed gear and spring to ensure consistent feeding and to handle the larger BB count without common high-capacity malfunctions.

This magazine is suited to long skirmishes or training sessions where 300 BB capacity reduces reload frequency. It’s designed for quick fitment and smooth BB delivery while maintaining a compact footprint and secure mount on compatible replicas.

Do not tamper with, disassemble or modify the magazine: unauthorised interventions may impair fit, safety and feeding mechanism. Store dry and protected from extreme temperatures and direct sunlight to preserve material properties and spring tension. Keep out of reach of children: not a toy.

For maintenance, regularly remove dust and BB residues from the interior feed path; use moderate compressed air or a dry cloth. Avoid aggressive solvents that may damage the nylon or inappropriate lubricants. Inspect the feed spring and gear for wear, deformation or loss of tension; replace the magazine if defects are found to ensure operational reliability.
