While the FDE anodized version is much easier to find, the black has not been made in many years. This is New Old Stock. "Vintage." LOL.
This rail is NEW, never mounted. Includes hardware. This is for FSB 14-1/2" or 16" barrels
Many collectors and clone builders consider the FSP version, with an opening for front sight block to be the preferable accurate Block 2 build rail!
Contains hardware. Does not contain RIS wrench.
