Luth-AR Front Sight Base, .750″, “F” Marked
The Luth-AR Front Sight Base, .750″, “F” Marked is designed for use with flat top upper receivers and a .750″ diameter barrel. The front sight base on the M16, M16A1 and M16A2 are shorter than the FSB on flat top ARs. The removable handle and shorter carbine sight radius requires a taller FSB to maintain the correct point of aim – point of impact. The “F” marking is lightly stamped into the gas tube cross bar.
*Note: Cross pin holes are not pre-drilled.
*Note: Front sight and gas tube hardware are not included.
