From the manufacturer

The Strike Industries PolyFlex Dust Cover for .223/5.56 offers a simple, quick and tool-less installation with its one-piece construction. Install in literally seconds by just pushing it into place. With our patent pending "True Seal" design, the internal lip seals the port tighter than traditional dust covers. Unlike stamped steel dust covers, this PolyFelx DC is made of durable and lightweight polymer which makes it resistant to rust. If the time ever comes, knowing you can remove and quickly reinstall makes this an easy cost-effective choice. Consider the Strike Industries PolyFlex Dust Cover for .223/5.56 for a new build or when you are going to untorque the barrel nut as th Mfg: Strike Industries
