The item that you are considering is a Unertl 8X scope with factory black adjustment mounts. This scope is similar to the ones used on the M1941 (1903 Springfield) sniper rifles as well as the USMC Winchester M70 snipers and occasionally other military weapons. I had this one on my M1941 until I found an actual issue USMC SNIPER marked scope. No, this one is not USMC SNIPER marked hence the price I have it listed. The USMC SNIPER marked scopes go for about 3 times what I have this listed at and I know because I paid for one. The scope functions perfectly and is 8x. The overall length is 21 3/4 long. The objective end diameter is 1 1/4 and the eye piece diameter is 3/4. The reticle is a fine cross hair with one speck on the horizontal hair. Yes, the metal screw on caps are intact and included. So if you are looking to put a scope on that Winchester M70 heavy barrel or your 1903 Springfield then here is your chance to save a few thousand dollars. If you have any questions then please feel free to contact me.
