Shiv,
That upper receiver is fine for the grendel. As far as I can tell, MOST grendels are built on standard upper receivers. Everyone Ive seen on an A3 or similar upper has dust cover that looks to be normal size. I have seen some custom oversize dust covers on another forum, but those were for the .50 beowulf.
