The Talley 2-Piece Picatinny Rail for Winchester Model 70 Magnum Length, .330 Rear Hole Spacing (Talley part no. 252701P) is a two-piece Picatinny rail for the Winchester Model 70 Post-64 Magnum length action with a rear screw hole spacing of .330 inch. Talley machines both pieces from 7000 series aluminum and hard-coat anodizes them to 65 Rockwell. The two-piece layout does not overbridge the action, so the rifle still top-loads easily. Any optic mount built to MIL-STD-1913 specifications then mounts on top, including Talley Picatinny rings.
