We like and recommend the T-1 for most applications for several reasons:
First, it is extremely rugged and absolutely reliable (like all Aimpoint sights). We routinely throw them around and drop them during classes to demonstrate their ruggedness. They get dinged and scratched, but they always keep working.
Next, the small tube size provides a very clean, unobstructed field of view. This improves situational awareness and speeds up target acquisition.
Finally, the short tube length buys extra space on the receiver rail, which allows for mounting of a back up iron sight AND a 3XMAG, PVS-14, or other device behind the sight.
The T-1 is suitable for use on rifles, carbines, shotguns, sub-machine guns, and handguns, either as a stand-alone sight or “piggybacked” on top of larger magnifying scopes, night vision, or thermal imaging optics. Note that, for AR-15 type rifles, a separate mount needs to be purchased.
The T-1 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 reflective lens reflects select frequencies of red light at near 100% efficiency in order to give the highest possible dot brightness. It also transmits 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 4 NVD-compatible brightness settings and 8 daylight settings (including one extra-bright setting), the Micro T-1 is ready for use anytime, anywhere, under any conditions.
