Magpul MAG1206 Enhanced Ejection Port Cover AR-15 M4 M16 Black

The Magpul MAG1206 Enhanced Ejection Port Cover eliminates the common problem of lost dust covers while providing superior protection for your AR-15's action. This black polymer upgrade replaces the standard military-issue cover with a more robust design that stays attached to your rifle.

What Makes This Different

Unlike standard ejection port covers that rely on a single pivot pin and easily detach, the MAG1206 features Magpul's enhanced retention system that prevents accidental loss during field stripping or maintenance. The cover incorporates a spring-loaded detent mechanism that provides positive engagement while allowing smooth operation. This design eliminates the frustration of hunting for dropped covers in the dirt or losing them entirely during cleaning sessions.

Key Features

• Enhanced retention system prevents accidental detachment during maintenance
• Spring-loaded detent provides positive lock-up and smooth cycling
• Reinforced polymer construction resists impact and temperature extremes
• Direct replacement for mil-spec ejection port covers on AR-15, M4, and M16 platforms
• Low-profile design maintains weapon aesthetics and function
• Textured grip surface for reliable manipulation with wet or gloved hands
• Matte black finish matches standard military and commercial receivers

Field performance demonstrates the MAG1206's reliability across temperature ranges from -40°F to 180°F without binding or failure. The enhanced retention system functions properly through thousands of cycling operations while maintaining dust and debris protection. Competition shooters and tactical operators report consistent performance in high round-count training scenarios where standard covers frequently detach.
