God Damn I love this thing. Love it so much I might just keep it as my primary sight. Any drawbacks to this? Seems as sturdy as a fixed sight. I was planning on buying an expensive red dot but I don't have a lot of money and a red dot seems bulky and cumbersome to me. Target acquisition is so much faster with this troy than my fixed. What do you think is the Troy dependable enough to be my only sight?
