Mesa Tactical Receiver Mount Picatinny Rail Standard Profile 4-1/2" Length for Mossberg 500

For attaching various optics to the Mossberg 500 shotgun, this M1913/Picatinny-style rail is installed using factory screw holes on top of the receiver (1997 and later Model 500's). The standard rail is for general optic mounting with a standard profile stock, while the tall rail is for use with the Mesa Tactical High Tube stock adapter. Both are constructed of 6061-T6 aluminum and are hard anodized.
