The Yankee Hill Machine flip rear sight is a folding backup iron sight for AR-style rifles. Many shooters run a red dot or magnified optic as their primary aiming system, and a flip-up sight gives them a lightweight, low-profile fallback that stays out of the way when folded and pops up when needed. Light at under a quarter pound, it adds redundancy without much weight. Yankee Hill Machine is a well-known name in AR accessories, and this sight is a sensible addition to a modern sporting rifle build.
