Seriously though, use some shorter rings, that scope may need a little red light on the top in case any planes come flying by...
Other than that, its pretty tastefully done. Not my style. But I do have a mismatched 91/30 that has some mangled up stock parts and an ATI stock...hmmm

ETA: your title says "Black Nagant", when just using "Nagant" it typically refers to the Nagant Revolver, not the Mosin Nagant Rifles...Thus the terms "M.N." or sometimes just "Mosin" or "Flame Thrower Rifle"
