Strike Industries Ultimate Dust Cover Capsule for AR-10, Black

Strike Industries built the Ultimate Dust Cover Capsule for AR-10 (part no. SI-AR-UDC-E-308-03-BK) to solve a common complaint with worn ejection port covers: a receiver that loosens with use and lets the dust cover flop open or shut too easily. This capsule uses an adjustable detent set screw so shooters can dial the opening tension back in as the receiver wears, instead of replacing parts.

Key Specifications

• Molded from black polymer for a lightweight, corrosion-proof ejection port cover.
• Features an adjustable detent set screw to compensate for receiver wear over time.
• Lets the shooter increase or decrease opening power to match feel and receiver tolerance.
• Built specifically for the AR-10 platform and its larger .308-length ejection port.
