YHM Gas Block Mounted Front Forearm Flip Sight Yankee Hill Tall BUIS
Flip up iron sights are a highly functional AR15 accessory for use with various optics. This durable, all steel AR15 Front Sight attaches to any Weaver or Picatinny rail to give you a Back-Up Iron Sight (BUIS). The sight folds out of the sight line with the push of a button and flips and locks in the deployed position with ease. Once placed in the up position, the AR or M4 Carbine Sight cannot be folded down without depressing the spring assisted detent release button located on the left side of the sight base. This totally eliminates the possibility of accidentally lowering the sight. Don't even consider an Iron Sight without this feature. This sight accepts all standard AR sight posts (included). The front sight post is adjustable for elevation.
YHM makes two front sight flip models. The YHM-9584 is taller and is designed for placement on railed gas blocks which have rails that are lower than the receiver flat top rail. Weight: 2.6oz
