The Spikes Tactical SED7000 Ejection Port Door provides reliable dust and debris protection for AR-15 platforms while maintaining smooth cycling operation. This black phosphate finished steel component replaces factory ejection port covers with enhanced durability and corrosion resistance.
What Makes This Different
Unlike standard aluminum port doors that can bend or crack under stress, the SED7000 utilizes hardened steel construction with black phosphate coating for superior longevity. The precision-machined tolerances ensure proper fit across multiple AR-15 manufacturers, while the enhanced spring tension maintains secure closure without binding during rapid fire sequences. This upgrade addresses common failure points found in mil-spec components through improved materials and manufacturing standards.
Key Features
- Hardened steel construction resists impact damage and wear
- Black phosphate finish provides corrosion resistance and low-profile appearance
- Drop-in replacement for standard AR-15/M16 ejection port covers
- Enhanced spring mechanism maintains proper tension through extended use
- Precision tolerances ensure compatibility with forged and billet receivers
- Heat-treated components withstand high round count firing schedules
- Factory-style installation requires no gunsmithing or modification
Field testing demonstrates consistent operation across temperature ranges from -20°F to 140°F, making this component suitable for competitive shooting, tactical applications, and hunting environments. The steel construction maintains dimensional stability during rapid heating and cooling cycles that can cause aluminum components to loosen or bind. Law enforcement and military users report improved reliability in sandy or dusty conditions where debris infiltration commonly causes malfunctions.
