Strike Industries UDC AR-15 Ultimate Dust Cover

Strike Industries UDC Ultimate Dust Cover Standard for AR-15 / M4 / M16 

Upgrade your AR platform with the Strike Industries UDC (Ultimate Dust Cover) Standard – an innovative quick-detach ejection port cover designed for AR-15, M16, and M4 rifles chambered in .223 / 5.56. Engineered for durability, reliability, and enhanced protection, the UDC is the first dust cover featuring a patent-pending internal sealing lip for superior resistance against dust, dirt, and environmental debris.

Unlike traditional metal dust covers, the Strike Industries UDC is constructed from high-density reinforced polymer, making it lightweight, corrosion-resistant, and highly durable. It will not rust, deform, fade, or bend out of shape even under demanding conditions.

The patent-pending spring-loaded internal detent rod system allows for extremely fast installation and removal in just 5–10 seconds without complicated tools or disassembly. An integrated adjustable detent set screw enables users to fine-tune the opening tension and compensate for receiver wear over time.

The SI Ultimate Dust Cover has been extensively tested and is compatible with a wide range of Mil-Spec AR receivers, including Colt, Daniel Defense, Noveske, LMT, Sig Sauer, Stag Arms, Kel-Tec, PWS, and many others.
