This is an exceptional example of one of the approximately 2,800 scopes developed and manufactured c.1940 for the U.S. Marine Corps, to be installed on 1903 National Match rifles by USMC/Navy armorers (a combination also known as the "USMC 1941 Sniper"). The scopes themselves were kept in inventory after World War II, seeing re-issue as late as Vietnam. It is marked "J. Unertl/USMC-SNIPER/2668" on the main body tube ahead of "8", with a rail-guided sliding aluminum front ring and an adjustable Unertl marked rear ring.

Excellent, retaining 98% original blue finish and sharp optics. The rings retain 95% plus original anodized finish. A must have accessory for the serious U.S. military collector.
