Description:
The Winchester Model 12, particularly the 2-pin version, is known for its milled rib design. This model features a rib that can be removed by disengaging it from the barrel using two pins. The 2-pin rib is a distinctive feature of certain grades of the Winchester Model 12, including Trap, Skeet, Pigeon, and Black Diamond models. These guns typically came with the large receiver ramp known as the Duckbill ramp. The 2-pin rib design allows for easier maintenance and customization of the shotgun's appearance and performance.
