How far is a Red Dot Accurate for an AR-15?
A red dot sight on an AR-15 is typically accurate for close to medium-range engagements, generally up to 100-200 yards.
Red dots provide quick target acquisition but lack magnification, so they are best suited for shorter distances. For engagements beyond 200 yards, their precision decreases as targets become smaller and harder to distinguish.
Some shooters use red dots effectively at 300 yards with practice, especially when paired with a magnifier. However, for longer-range precision beyond 200 yards, a scope or Low-power variable optic (LPVO) is usually more suitable.
