If the other Lancer Tactical M4 magazines arent your cup of tea, theres always the black version. It fits almost all M4 AEG rifles along with Lancer Tacticals. Fire rate doesnt matter as it feeds like a dream.
While not as easy to see, this magazine also has a window to help you check your rounds. That way, you wont keep firing when the gun is empty.

Features:

• Consistent BB feeding, even in high-rate-of-fire HPA guns
• Transparent window for monitoring remaining BB count
• Impact-resistant polymer construction with rugged texture
• Compatible with Lancer Tactical Proline Series and most M4 airsoft AEGs
• Features 3 digital numbers on both sides for easy identification marking
• Removable magazine baseplate for quick draws
