Manufactured by the Unertl Optic Company as a 10x USMC 7.62x51 mm NATO calibrated optic, issued for use on top of M40A1 to M40A3 pattern bolt action sniper rifles. The left side of the adjustment body is marked "USMC SNIPER" with the serial number "1552" underneath. The elevation knob is graduated from 100 to 1,000 yards. Fitted with a pair of Badger ordnance scope rings (each marked "0366") with the front ring fitted with a SIMRAD night vision attachment point. The scope body and rings are spray painted in a desert tan scheme with tape on both objective bells to seal focus and parallax adjustment from sand.
