So I just purchased my first nagant at the gun show today. Spent a hundred bucks, and by the looks I'm happy. But cupple questions. It seems to be all greased up. I mean its on everything. Can I take it or most of it off? Will it effect the rifle? Second, it seems the barrel is a tad bit loose. And I mean just a tad. The wood on top of The barrel is loose so The barrel moves a slight bit. Should I be worried? And is there any way to find out where its been. All four serial numbers match, barrel, butt, bolt and the bottom of the clip. Paid a hundred flat and its now in my name. Don't know if it was a good deal but big 5 wanted 120 for there's. Any info is appreciated. And as always, Thx.
