Meprolight showed off their new Micro RDS Quick Release System for pistols. Their Micro RDS connects to their rear sights and has a quick release system that returns to zero when re-attached. The iron sights that the Micro RDS attaches to also has a three dot Tritium night sight setup. Check it out in the video above.
Pretty slick idea, they should come out with a mount system for the RMR as well.
