Slight difference in the specs would probably be the key. I think the Omega has good eye relief. On a muzzlelaoder that is something you will find handy. The Omega is also set up for ballistics on what you might find with the muzzleloader velocity, I wonder what the other is set at.

I never was a fan of the BDC but a lot of people like them so they must have merit. What's the eye releif and over all length on the Team Primos?
