Item # 291488 Style STR-SI-AR-OMUDC-223-BK UPC 793811764758 Condition New Manufacturer [Strike Industries](https://www.kygunco.com/brand/strike-industries) Weight 1 lb **Strike Industries AR Overmolded Ultimate Dust Cover (.223/5.56)** The next evolution of the UDC, this overmolded design uses a double-injection process and a rubberized soft sealing lip to improve the seal and help keep debris and water out when closed. The patent-pending “True Seal” internal lip tightens the seal beyond traditional covers, while noise-reduction padding makes activation nearly silent. It arrives pre-assembled for quick, tool-less installation and easy disassembly with something as simple as a pen. Built from high-strength, impact-resistant SI Polymer Extreme, it won’t deform, rust, or bend out of shape. Ideal for new builds or whenever you’re breaking barrel torque, you can install and remove any SI UDC in just 5–10 seconds. **Product Features** - Upgraded UDC with double injection mold and overmolded rubberized seal - Quick, tool-less installation and easy disassembly (use a pen or small point) - Patent-pending “True Seal” internal lip for a tighter port seal than traditional covers - Overmolded soft sealing lip helps block debris and water when closed - Built-in adjustable detent set screw to compensate for upper receiver wear - Patent-pending noise-reduction rubber padding for nearly silent activation - High-strength, impact-resistant SI Polymer Extreme construction resists deformation - Rust-resistant vs. traditional steel covers - Install and remove in just 5–10 seconds **Compatibility** - AR-15 Mil-Spec upper receivers - Most billet AR-15 upper receivers - Aero Precision M4E1 ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
