3-Gun Sight Options for ARs with Barry Dueck

Ace 3-gun competitor Barry Duke demos combo of 1.5-5X top-mount optic with side-mounted iron sights for 3-gun AR carbines. The Duke defense iron sights allow fast transitions from magnified view for far targets to a 1:1 view of close targets. Barry finds this set-up very fast and the iron sights are “dead-nuts” reliable in all situations.
