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.
