This is by no means accurate, but I want a "live fire" DL44 and this is the closest I will probably ever come. I thought about checking to see if the M712 can be accurized, but in the end there are so many little things that are off compared to a C96 that I don't think it would be worth it. The Umarex uses 4.5 mm steel BB's and is a CO2 powered gun that only comes with a long magazine. It has a single shot and full auto option. Right off the bat I wanted to remove the shot selector and make this single shot only, but the way the trigger mechanism is put together you have to have the selector parts in place. Still thinking about that.

This is what i started out with
Then I was lucky enough to get one of the DEC kits from the latest run (parts are hot glue gunned on to see how they fit)
With all the parts in place I could start thinking about the build. The biggest obstacle is the 18 round long magazine- It takes a CO2 cartridge, no way to cut it down and still have it be functional. Marushin used to make a 6mm and 8mm airsoft M712 that came with a gas blow back short magazine. The 8mm short mag is still available from some of the retailers in Asia. The Umarex is based on the Marushin and the magazines looked close enough in the pictures that I decided to give it a try and ordered one.

After receiving the wrong mag, returning it, and finally getting the right one I looked things over. The general dimensions are very close. The 4.5 mm head will fit on the 8mm mag with no problem and aligns in the chamber. BUT
1) the short mag is wider then the original- the Umarex mag has a slight taper towards the front. Easily fixed on the sander.
2) The 8mm ammo well will have to be sleeved to fit the 4.5 mm BB. Should not be a big issue, just have to find the right tubing. There is also a follower slot I will have to cut into the mag. In the last shot below they look like they have different dimensions, but it is just the way the mags are angled.
Magazine heads- the red is for 8mm
The 4.5 mm head in the 8 mm magazine:
3) The locking catch on the short magazine is smaller than on the Umarex mag. I fixed this by elongating the mag catch stop inside the gun to allow it to extend out a few mm further into the magwell.
The mag will now slide in and catch with no issues and is lined up within the chamber. First picture is with the top half of the gun removed, second shows the mag in the firing chamber.
And finally it fits.
Note the way the grill fits- the M712 has a flat front where the C96 is more rounded. I have not decided what to do about this yet. I plan to strip and blue the entire gun so I can't just use filler to round off the front end.
The majority of the barrel is held on by one allen screw. Fitting the bull barrel on this thing is a breeze.
I will update this as it goes, tomorrow I am going to work on the E-11 for a while...
Thank You

Im gonna be shoving in a blaster core for sound and lights in the mag well so I won't be doing a mag like yours but did you get it to fire yet with the shorter mag?
