The long eye relief of 3.9 inches and an ultra-forgiving eye box make target acquisition quick and comfortable. One downside to consider is that the scope is on the heavier side, weighing in at 2 pounds, which might add noticeable weight to your rifle. Additionally, it does not have night vision capabilities.
