General Description
MOUNT, TELESCOPE: M146 forms an adjustable base to support TELESCOPE:M118C and M118 right-hand installation on barrel of HOWITZER, MEDIUM, SELF-PROPELLED, FULL-TRACKED, 155-mm and HOWITZER, LIGHT, SELF-PROPELLED, FULL-TRACKED, 105-mm.

Bore sight knob assemblies are provided to facilitate both ballistic and bore adjustment control for elevation and azimuth alignment by angularly transporting the entire telescope within the mount. The controls are automatically locked at any desired setting. Adjustable scales calibrated in tenths of a mil simplify corrections required for factors peculiar to the individual weapon and/or its emplacement.

Cant correction is achieved by rotating the entire telescope between the telescope ball supported at the forward end, and the fixed telescope sleeve near the opposite end, thereby erecting the reticle pattern. A single tapered kingpin secures the telescope in the mount in alternate mating holes and can be removed without the use of tools. A cable assembly is connected between the vehicle and power supply and the telescope to illuminate the reticles and level vial.
