Iron Sights for AR's
Since a-lot of guys want to use irons in some capacity, it may be of value to everyone to see what types of irons guys use specifically on an AR frame, for what purpose, and how well those particular irons have worked. Let me throw this out and see what you guys are using and why. No need to comment on all of them.
If you were to buy irons for hunting medium game to 300, what would they be and why?
If you were to buy irons for LEA, Military or Action Shooting purposes, what would they be and why?
If you were to buy irons to improve your own marksmanship ability when firing from unsupported positions (Standing, Kneeling, Prone, Seated), what would they be and why?
What, are your lessons learned from buying, mounting / dismounting, and using iron sights on your ARís?
