Magpul MAG1206-ODG Enhanced Ejection Port Cover OD Green AR-15 M4

The Magpul MAG1206-ODG Enhanced Ejection Port Cover eliminates the common failure point of standard military-spec dust covers while providing superior protection for AR-15, M4, and M16 upper receivers. This OD Green polymer upgrade replaces the factory steel cover with an improved design that won't bind or break under heavy use.

What Makes This Different

Unlike standard GI dust covers that rely on a single pivot pin and spring-loaded detent, the Magpul Enhanced Ejection Port Cover features a reinforced polymer construction with an integrated torsion bar. The design eliminates the detent system entirely, reducing parts count while improving reliability. Testing shows 40% better retention force compared to military specification covers, with no reported failures after 10,000+ round evaluations.

Key Features

• Reinforced polymer construction resists impact damage and temperature extremes
• Integrated torsion bar eliminates detent spring failure points
• Self-centering design maintains consistent ejection port seal
• OD Green finish matches Magpul furniture and military equipment
• Drop-in replacement for mil-spec AR-15, M4, and M16 upper receivers
• Oversized paddle provides positive manipulation with gloves
• Corrosion-resistant materials withstand saltwater and chemical exposure

Field testing across multiple environments demonstrates consistent operation from -40°F to 140°F without binding or premature wear. The enhanced design maintains ejection port protection during rapid fire sequences while allowing immediate access when needed. Law enforcement agencies report zero maintenance issues after 18 months of patrol rifle deployment, while competitive shooters note improved consistency during high round count matches.
