Very Nice. by Mike, December 6, 2014
There is no denying this red dot is expensive, but I believe you 'usually' get what you pay for. The M4 Red Dot is one of the most well made high quality optics I have seen. I have a Leupold scope on my .270 that I bought used and it's as solid as ...

Product Info for Aimpoint CompM4 Red Dot Sight (No Mount)

AimPoint CompM4 and CompM4s 2 MOA Red Dot Sight w/out Mount are the finest sights that Aimpoint has ever produced. Improvements include improved energy efficiency that provides up to 8 years of continuous use from a single AA battery!image

Aimpoint Red Dot Sights from CompM4 series of sights are available in two versions: The CompM4 offers a high battery compartment, while the CompM4s offers a low battery compartment. In all other aspects, the Aimpoint CompM4 and Aimpoint CompM4s Red Dot Sight are identical.

The CompM4 is now the latest version of the US Army's M68 CCO (Close-Combat Optic), continuing a legacy that Aimpoint has maintained since 1997. The performance of the CompM4 series of sights is optimized for use with all generations of night vision devices (NVDs), but is especially suited for 3rd generation night vision technology. Aimpoint 's unique band-pass coating on the front lens reflects select frequencies of red light at near 100% efficiency in order to give the highest possible dot brightness with the smallest amount of energy while transmitting nearly 100% of light in the Infrared and near-infrared part of the spectrum to provide the clearest, brightest image possible when used with a 3rd generation NVD. With 7 NVD-compatible brightness settings and 9 Daylight settings including one extra-bright setting, the Red Dot Sight CompM4 and CompM4s by Aimpoint are ready for use around the clock.
