In 2007, Aimpoint set the bar high for the micro red dot sight (MRD), which was then new to the market. Until then, military grade red dot sights were fairly large, consisting of a wide 30mm tube with a battery compartment slung off the side. While very effective in combat and in the civilian hunting and shooting sports, they added bulk and weight to the firearm. This proved cumbersome, especially for competition shooters mounting red dots to their pistols. When Aimpoint launched its Micro Red Dot series, it took all the reliability, durability and long battery life of its proven larger red dots and crammed it into a small, light-weight package.
Originally Aimpoint had three micro models, the T-1, H-1 and R-1. All three shared the same physical dimensions, weight and operating controls, but they were intended for different applications. The T-1 was designed primarily for a military and law enforcement application, while the H-1 and R-1 were intended for the American hunter and competition shooter respectively. As the R-1 has been discontinued and the primary difference from the H-1 is the color (silver instead of black), this article will only address the T-1 and the H-1. The different specifications between the T-1 and the H-1 are their availability of night vision settings, operating temperature ranges, water resistance and color. The military and Law Enforcement T-1 has four night vision settings and is rated for operation in -50 to 160 degrees Fahrenheit. It is also submersible to 80 feet. These extra features come at a premium, and the T-1 commands a higher price point than the H-1. The H-1 looks like the more expensive T-1, but it lacks the night vision settings, has an operating temperature range of -20 to 140 degrees Fahrenheit and is only submersible to 15 feet. The H-1 also has more distinct manufacture and product markings than the T-1.
