SI (Strike Industries) just released another version of their SI Ultimate Dust Cover with a new Flag design. The previous version had more of a looping / flowing flag design. The new design features more straight lines that go better with the lines of an AR15. The coolest part about the SI UDCs is that they can be installed in seconds without needing to remove the handguard. They have a spring loaded pin that can be manually retracted for easy installation.
The new Flag model of the SI Ultimate Dust Cover is finally in stock and shipping now in black and FDE!
