Unertl Optical Company, Inc. was a manufacturer of telescopic sights in the United States from 1928 until 2008. They are known for their 10× fixed-power scopes that were used on the Marine Corps' M40 rifle and made famous by Marine Corps Scout Sniper Carlos Hathcock during the Vietnam War.
The scope body is sealed and filled with nitrogen, which prevents fogging of optics and was designed to function within a -50 °C to 50 °C temperature range. For zeroing the telescopic sight the reticle can be adjusted by manipulating the elevation and windage turrets in 5 centimetres (2.0 in) at 100 metres (109 yd) (0.5 mil or 1.72 MOA ...
The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.
When using a scope with both mrad adjustment and a reticle with mrad markings (called a mrad/mrad scope), the shooter can spot his own bullet impact and easily correct the sight if needed. If the shot was a miss, the mrad reticle can simply be used as a "ruler" to count the number of milliradians the shot was off target.

A Sniper Advanced Targeting Pod hangs from the underbelly of a B-1B Lancer A Sniper pod on an F-16s hardpoint.. The Lockheed Martin Sniper is a targeting pod for military aircraft that provides positive target identification, autonomous tracking, GPS coordinate generation, and precise weapons guidance from extended standoff ranges.
Since the BORS is mounted directly to the scope and coupled with the elevation knobs, the computer can interact with the scope by simply turning the elevation knob until the LCD displays the target’s range. [1] The kit includes the proprietary Barrett Ballistic Software that is pre-programmed with a library selected by Barrett. It also ...
