Buck Mark Scope Base Attaches in place of the stock top strap on most Buck Mark pistols. Machined from aircraft-grade alloy Current versions of this base use the Picatinny style rail slots and spacing* This style base is not compatible with the proprietary Browning rings
*IMPORTANT: Some earlier versions of this rail were sold using the Weaver-style configuration of slots and spacing. Before purchasing, check the packaging to confirm that the sight you have fits the base on your firearm. The general rule is that Weaver-style devices will fit on Picatinny-style rails, but Picatinny-style devices will not always fit on Weaver-style rails.
