Armalite M-15 A1 Front Sight Base Clamp On With Screws

Forged-steel clamp-on front sight base/gas block allows the shooter to zero the front sight so that the rear sight is perfectly centered. Massive clamp screws hold the base tightly in place without the bore deformation that is common to the usual, difficult to service pins. No pins required allows this sight to be easily reusable. Includes screws.
