Flip-up front sight deploys with the flick of a finger to provide instant back-up to keep you in the fight if your Sig 556’s primary optics or laser sight fails. Fits the factory dovetail on the gas block, and is the correct height to allow use of any Midwest Industries AR-15 flip-up rear sight. Uses standard A2 front sight post to ensure correct sight picture and easy adjustment using an A2 front sight tool. Super-smooth pivot mechanism with sturdy ball-bearing detent locks positively in the raised position and stays locked until you hit the pushbutton release. Folds down neatly out of your sight path when not in use.
SPECS: 6061 T6 aluminum, hardcoat anodized, matte black.
