⚙️ Product Details

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.
