Question: what is the difference between aimpoint h1 and t1?
Answer: Both optics utilize a 4 or a 2 MOA red dot as it's reticle. The H1 features 12 daylight settings and offers the most versatility from dawn to dusk shooting. The 12 setting also provide an overall brighter red dot for those with vision issues. The T1, however, offers 8 daylight settings and 4-night vision settings.
