The MCR will not top cover will not close on a live round nor will a live round be able to be pulled through the mechanism. The blank discriminator is clearly visible on feed and ejection sides of the weapon with the top cover open or closed.
The design remains untested on Gen 1-5 MCRs but is fully compatible with my 3D printed starter tabs found on my page.
Non M200 blanks such as German DAG 5.56 blanks are likely not compatible with the system
