I will try mine on my 52cal LRH and see how the eye relief works out first. It uses the same rings and bases, plus it does not have a "permanent" scope yet. It currently has the cheap Simmon 4x Pro Diamond with a longer relief so the Omega might be ok too.

I would actually prefer a non BDC for the GMB54 though but i can live with it. That is a killer price even with shipping.

I just compared specs and i think i will stick with my Redfileds for now. Mine is lighter and FOV is pretty close. Plus i know it works great on my Knights. Thanks for the heads up though. I will still give mine a try on the 52cal LRH build because 2oz of weight isn't as important and the BDC might be useful on that gun.
