It is a milspec firearm., not a sporting arm. It will have machining marks, lathe marks, grinding marks etc. This is what makes it look , feel and be a miltary type weapon. If you want to improve the looks., I would suggest disassembly, degrease and give it a nice coat of semi-gloss Appliance Epoxy from a rattle can right over the original phosphate finish., and dry 4 hours then bake for an hour in the oven at 275. Your rifle., do as you see fit.
