The Elcan SpecterM145 is the U.S. government model (NSN 1240-01-411-6350) of the ELCAN 3.4x magnification optical rifle sight employed as the standard machine gun optical sight (MGO). The front objective is fitted with a laser filter and Signature Reduction Device.

The M145 M4 is a variant of the M145 Machine Gun Optic with a 'M4' reticle that is optimized for use on the M4 Carbine, M16 rifle and derivatives. Aside from the reticle, it is the same mechanically and optically as the M145 Machine Gun Optic.

不过美军所装备的型号作了一些改进，包括在物镜前加上防反光装置，取消了后备机械瞄具等，并重新命名为M145 MGO（MachineGun Optic，即“机枪光学瞄准镜”）。另外还专门为卡宾枪及机枪配用了两种不同的分划。

MIL-SPEC Rated Waterproof to 20 Meters (66 Feet) for 2 Hours. Eye relief (Cheekweld) and bore sighting remain constant. Large, low light exit pupil remains constant. High efficiency coatings for extended low light performance. Retains Zero Time-After-Time for Dependability with your Accuracy. Rugged, Reliable Performance.
