    I've been thinking about a magazine fed mag but I think I would like mine to be a side feed with more of the sten/sterling look. can't wait to see this one work.

        There are a few members here who have done top and side-fed mags. On those, you don't have to move the frame or drill the rail. So it's really just a matter of drilling the side of the body, milling the barrel to feed horizontal, and attaching the magwell to the body. I know at least one guy 3D printed a magwell with a "cuff" that slid over the body. If it were me, I'd probably just dremel a thin stretch of material out of the rail in 2 places so I could hose clamp the magwell straight onto the body.

        If you have access to a machinist, another option would be to make 2 small aluminum blocks that the magwell can bolt onto and then braze those onto the body in the right place. It would look cleaner and be a lot more stable than the hose clamps. The blocks would be flat on 5 sides and radiused to the body on the other side. Probably an easy build.

        All of this gets even easier with a Doc's cocker adapter. I think that will probably be how I finish this build, but we'll get it knocked out this way first.

          Had the work done on the frame last night. It serves its purpose really well, but I need to shave some meant from under the rail so the stock can fit in there and still let my trigger fix sit under the frame screw. there might be an easier way to do this, but I haven't found it. Feel free to offer up advice.






          and just a note, the way the actuator sits on the trigger plate still allows you to use an allen wrench to tighten the frame screw.

                  I thought you were going to link something with the word "this" in post #20.

                  I see now it doesn't have to be interpreted that way. What do you mean by "dual mag"?

                      I recently bought a T2W stock. I've wanted one for a long time and this build seemed the perfect time (and excuse) to do it.

                      So this is the way the back half of the bottom-fed mag is going to look.




                      You can see the sketching on the rail. That is how it will be milled to allow the main rail to sit down on it. This was an old, very rough rail that I got cheap so it's not hurting anything that wasn't already damaged.
                      I'm going to have the Kapp drop milled so that the cradle can slide all the way back to the bend. I'll then cut off the extra post and that will give the magazine room in front of it.

                      I think we're getting to the point of this not only functioning well, but looking decent too.

                        I've been working on this some in order to finish it before our move back to Africa.
                        I'll get some updates and more pics, but wanted to go ahead and put out there that I'll be getting rid of this project before moving. If anyone is interested, PM me.

                          Wow that's a very interesting build ! Can't wait to see it finished
                          I'm assuming you bolt the back half of the grip frame to the stock that runs in between ( post # 10 ) ?
