    Building Grease Gun Magwells for a MAC 10/45 Clone.

    In conjunction with my previous post regarding the die set I built to form the MAC 10/45 clone lower receiver, I’ve also built a die set to form the magwell for same. This magwell is designed to use 45 ACP grease gun magazines.

    For the magwell, I took measurements from a Velocity Firearms magwell that I had previously purchased. They are formed of 16 ga. CRS.

    The die set for forming the magwell consists of a punch [or mandrel] and a cavity die. The punch was made from several pieces of mild steel bar stock, welded together, then milled to the internal dimensions of the Velocity magwell. The overall length was left slightly long. The cavity die was made from a block of ¾” thick mild steel and two lengths of 1 in. x ¼” angle. The angles were structural remnants with nicely rounded edges which only required a little smoothing/polishing with a scotchbrite pad.

    Once the magwell was formed, the back seam was tack welded and the relief cuts for the magazine stop stud channels were cut into both sides. This method of making these channels is detailed in the drawings found in the PDF file titled ‘Machinist Drawings for Sub-Machine Gun Frames’. This document can be found online through a web search.

    To obtain the rounded semi-circular shape for the mag stop channels, I built another die set as shown in the photos. Once formed, the side seams were welded, as was the back seam. A threaded boss was welded on for mounting the composite backstrap, and a relief was cut for the mag release.

    The magwells are commercially available [Velocity Firearms is one vendor]. When I last checked pricing, they were $20.00 ea., plus shipping.

    For a couple of dollars I purchased enough 16 ga. CRS from my local supplier to make half a dozen.

    Time to get on with these builds….
