The Williams Gun Sight WGOS Front Sight Base (Williams part no. 001568) in black is sized to clamp onto barrels measuring between .730 and .830 inches in diameter, giving a shooter or gunsmith a correct-fit base for mounting a compatible front sight blade or bead on a rifle or shotgun barrel within that range. At .290 inches tall, the base sets a specific sight height that needs to be matched with the corresponding rear sight for a correct sight picture. Getting barrel diameter right matters for a secure clamp fit, so measuring the barrel before ordering is an important step. It’s a foundational part for anyone building or restoring a front sight setup on a barrel in this diameter range.
