The Strike Industries AR Overmolded Ultimate Dust Cover for .223/5.56 is the next iteration of our Ultimate Dust Cover (UDC). The upgraded UDC design with double injection mold and overmolded rubberized soft sealing lip for better seal to prevent debris and water from entering when the cover is closed. The SI patent pending ""True Seal"" internal lip seals the port tighter than traditional dust cover designs. The AR Overmolded UDC comes pre-assembled with all the parts needed for a quick tool-less installation and easy disassembly using something as common as a pen or small point. Built into the UDC is an adjustable detent set screw to compensate for wear on the upper receiver. The SI patent pending noise-reduction rubber padding also makes it nearly 100% silent during activation. Made of overmolded high-strength impact resistant custom blended SI Polmer Extreme material, the SI AR Overmolded UDC does not deform or get bent out of shape. Resistant to rust unlike traditional steel covers, if the time ever comes, knowing you can remove and quickly reinstall makes this an easy cost-effective choice. Consider the Strike Industries AR Overmolded Ultimate Dust Cover for .223/5.56 on a new build or when you are going to untorque the barrel nut as this is the easiest time to remove your old stamped steel dust cover to upgrade. Install AND remove any SI UDC in just 5 to 10 seconds. COMPATIBILITY:
