HERE IS A NICE LYMAN 17A "XNA" FRONT TARGET SIGHT. THIS SIGHT WAS MADE SPECIFICALLY FOR SPRINGFIELD 1903 .30 CALIBER RIFLE. THE SIGHT IS IN VERY GOOD SHAPE, HAS GOOD COLOR AND COMES WITH 4 ORIGINAL SIGHT DISCS. LYMAN 17A SIGHT DISCS ARE SOLD ON A WEEKLY BASIS SO YOU WILL HAVE NO PROBLEM FINDING EXTRA ONES. THE SIGHT IS STAMPED "LYMAN" ON THE SIDE OF IT. THE SIGHT DOES NOT HAVE IT'S "XNA" STAMPED ON THE BOTTOM OF IT'S DOVETAIL BECAUSE THE BOTTOM OF THE DOVETAIL HAS BEEN FILED ON JUST A HAIR BUT IT SHOULD STILL FIT YOUR DOVETAIL JUST FINE. ANY LIGHT SPOTS YOU SEE ON THE SIGHT IS JUST THE REFLECTION FROM THE OVERHEAD LIGHT AS THE SIGHT HAS A NICE UNIFORM DARK BLUE COLOR. PLEASE LOOK AT MY OTHER sales AS I HAVE SEVERAL OTHER WINCHESTER, MOSSBERG, REMINGTON, MARLIN, LYMAN, REDFIELD AND OTHER VINTAGE SIGHTS FOR SALE.
