Strike Industries ARUDCE0122 Ultimate Dust Cover AR-15 Black Polymer

The Strike Industries ARUDCE0122 Ultimate Dust Cover transforms standard AR-15 protection with enhanced sealing capabilities and tool-free installation. This polymer dust cover addresses common issues with mil-spec designs that allow debris infiltration during extended field use.

What Makes This Different

Unlike standard aluminum dust covers that rely solely on spring tension, this design incorporates improved sealing surfaces and a reinforced pivot mechanism. The polymer construction resists corrosion while maintaining proper tension over thousands of cycling operations. Enhanced contact points create a more secure seal against dust, moisture, and fouling compared to basic military specification covers.

Key Features

• Enhanced polymer construction resists corrosion and impact damage
• Improved sealing design blocks fine dust and moisture infiltration
• Tool-free installation fits standard AR-15, M4, and M16 upper receivers
• Reinforced pivot pin assembly maintains proper tension over time
• Low-profile 3.46-inch length accommodates most accessories
• Matte black finish matches standard receiver coatings
• Spring-loaded mechanism provides reliable automatic closure

Field testing demonstrates superior protection in sandy and dusty environments where standard covers often fail to maintain adequate seals. The polymer material withstands temperature extremes from -20°F to 160°F without cracking or warping. Competition shooters report consistent function even after extended rapid-fire strings that generate significant heat buildup.

Technical Specs

• Length: 3.46 inches
• Material: High-strength polymer construction
• Finish: Matte black
• Compatibility: AR-15, M4, M16 platform rifles
• Weight: Approximately 0.8 ounces
