The Omega barrel should be free floated when you got it. Have you done the Dollar bill test this is what I'm talking about Gunsmithing - How to Free Float a Rifle Barrel Presented by Larry Potterfield of MidwayUSA - YouTube
You will only be able to go back to the 1st lug then it should stop. If you have no resistance till that point you should be good. I do this every time I remove the stock & reassemble. Like HM said if it's not effecting the gun down range I would not worry about it.
