The G11 was stopped very early in the development curve. The concept is valid, but this particular design is not yet a viable weapon.
Recall that HK submitted this design for the US ACR trials. It, along with all the others, were rejected as not being a sufficient improvement over the M16. See a photo on page 294 of Military Small Arms Of The 20th Century.
