LBE Unlimited AREPC AR-15 Ejection Port Cover Assembly Black Steel

The LBE Unlimited AREPC AR-15 Ejection Port Cover Assembly provides reliable dust and debris protection for your AR-15 upper receiver. This black steel cover assembly maintains proper ejection port function while preventing contamination during storage and transport.

What Makes This Different

Unlike basic stamped covers, this assembly features precision-machined steel construction with proper spring tension calibration. The black finish resists corrosion better than standard phosphate coatings. Installation requires no special tools and maintains mil-spec dimensions for consistent function across different upper receivers.

Key Features

• Precision-machined black steel construction for long-term durability
• Mil-spec dimensions ensure proper fit on standard AR-15 upper receivers
• Corrosion-resistant black finish withstands harsh environmental conditions
• Spring-loaded mechanism provides reliable open/close operation
• Tool-free installation with included roll pin and detent spring
• Compatible with all standard AR-15/M16 upper receivers
• Maintains proper ejection timing and brass deflection patterns

Field testing demonstrates consistent operation through thousands of rounds without spring fatigue or binding issues. The cover opens smoothly during firing sequences and closes automatically when the bolt carrier group returns to battery. Weather exposure tests show the black finish maintains integrity through rain, sand, and temperature extremes from -20°F to 140°F.
