Strike Industries Ultimate Dust Cover — AR-10 .308, FDE

The Strike Industries Ultimate Dust Cover in Flat Dark Earth (SI-AR-UDC-E-308-01-FDE) is a high-density polymer replacement for the standard AR-10 .308 ejection port cover. Built tougher than a stamped steel factory cover, the SI UDC resists corrosion, deformation, and fading. The spring-loaded internal detent rod lets you attach or remove the cover in 5 to 10 seconds — no tools required.

Strike Industries UDC .308 FDE — Features & Design

The SI UDC .308 uses a high-density polymer construction that will not corrode, rust, bend, or deform over time. Key design features include:

• Spring-loaded internal detent rod — attaches and detaches in 5 to 10 seconds for fast field stripping
• Adjustable tension set screw — compensates for receiver wear and lets you dial in opening resistance over time
• High-density polymer build — lighter than steel, resistant to corrosion and deformation
• Flat Dark Earth (FDE) finish — will not corrode, rust, or fade
