Yes, Ronin does good work. I have one of his older VZ58 grips in dark grey on my rifle now. Besides the new grip you posted, he also makes a taller regular VZ58 grip. It looks like the original shape but is ?? taller for a better grip. They are only $20, US made and count as a compliance part.
They are near the bottom of this page:
