930 SPX Tri-Rail from Aimpro I received the new rail for the 930 SPX from Mike Shain at Aimpro today. Here are some pics. The rail arrived in a sealed plastic sleeve, wrapped in shipping foam in a heavy cardboard box. The package includes the rail assembly and 12 soft rail ladder covers. Bottom view of the rail assembly. End closest to camera is the receiver end. Muzzle end view of the rail. This view shows the collar that fits the rail to the barrel lug/piston collar. Side view of muzzle end of the rail assembly. Screws secure the collar inside the rail body. Looking inside the rail body, from the receiver end towards the muzzle end.
