Most all good rifles coming from the manufacturer will be well lubed. First of all so they will properly function if the proud owner takes them straight out of the box and shoots them. Also for shelf life protection against any corrosion should the rifle set on a shelf in a warehouse or at a dealers for a long period of time. I know Rock River Arms when the rifle gets back from the live fire test on the outdoor range, which everyone of them goes through. They are then cleaned while going through the rifle's final inspection, lubed with G-96 and packed in the box ready to go out the door! So it is common for good rifles like yours to be well lubricated. And while we are on it, you need to keep your bolt and carrier assembly always looking a little wet and you will not have any problem. A damp AR Rifle is a Happy AR Rifle!
Nice rifle and it looks like Old Santa was good to you! Give us some range reports when you get a chance.
