Integral gas block and folding front sight replicates the strength and appearance of the classic factory AR-15/M16 front sight tower, yet folds neatly out of the way when it’s not needed. Weight-saving, all-in-one design; no need to purchase a railed gas block and a separate rail-mount folding sight. Deploys and locks securely open with the flick of a finger—as fast as any flip-up combat sight. To fold, press straight down on the top of the diagonal rear support to release the lock while pulling back on the sight tower. Standard, A2-type sight post is the same height as factory post, so it works with any factory height rear sight. Easy to install; dual clamping rings fit standard .750" diameter barrels, and hex-head bolts (hex wrench included) provide plenty of clamping force to make sure the sight doesn’t shift and change point of aim. Base/gas block of rugged, precision machined steel provides exceptional strength and resistance to erosion by hot gases. Includes bayonet lug, and rear clamping ring drilled to accept sling swivel pin. Aluminum sight post minimizes weight while still providing plenty of strength. Uniform, black finish matches most factory gun finishes.

SPECS: Steel and aluminum, matte black finish. Fits barrels that are .750” O.D. at the gas port.
