The Strike Industries Enhanced Ultimate Dust Cover - Capsule is a quick-install polymer ejection-port cover for compatible AR-15 upper receivers. The spring-loaded internal detent rod allows the cover to be installed or removed without the traditional process of driving a standard retaining rod through the upper assembly.
The enhanced UDC-E design adds an access window for easier disassembly, a thinner profile for broader receiver fitment, an adjustable ball-detent screw, and Strike Industries’ internal True Seal lip.
Key Features
- Capsule-pattern enhanced Ultimate Dust Cover
- Spring-loaded internal detent rod
- Quick installation and removal
- Adjustable ball-detent set screw
- Cutout window for easier disassembly
- True Seal internal lip
- Lightweight high-density polymer construction
- Corrosion-resistant polymer body
Compatibility Notes
Strike Industries lists the UDC-E for AR-15 Mil-Spec upper receivers, most billet AR-15 upper receivers, and the Aero Precision M4E1. The manufacturer lists the VLTOR MUR and ZRO Delta as incompatible and also notes interference with certain adjustable or enhanced bolt-carrier designs. Confirm upper-receiver and carrier clearance before ordering.
