The receiver is roll-marked "Mossberg - MADE IN U.S.A. - NORTH HAVEN, CONN. - 500A 12 GA." The 500A suffix denotes the 12-gauge variant within the Model 500 series, providing clear identification for parts-matching and documentation.
Construction is aluminum alloy with a matte black finish. The right-side ejection port is cut, and the bottom trigger-housing window has the cross-pin holes in place, consistent with Model 500 pattern receivers.
Controls include an ambidextrous top-tang manual safety with a red indicator dot. The receiver retains the classic Model 500 layout while offering straightforward, familiar ergonomics.
The top of the receiver is drilled and tapped and fitted with five plug screws. This preserves a clean profile while allowing future setup changes as needed.
