I got jhartman's old Denix when he upgraded. He'd already done a lot of work, but I've continued in this vein. It's lovely to see what others are doing with these. One of the main things I saw to tackle was reshaping the breech:
That is my beater denix. You can see all sorts of “experiments” already done to itJust be careful! Taking material off is easy, adding it back on not so much. Practice on a scrapper Denix lower first; I learned that the hard way. Also; this area isn't flat but has a distinct curve to it, so don't just make it a flat bevel.
I did that with my Denix a few years ago. Before drilling the new holes, I had first epoxied aluminium L-brackets for reinforcement on the inside and above the hole. I also had to route some more space inside the upper for the new bumps to fit. (Apparently I did also shave off a mm off the top to make the upper sit lower)You can slide the whole top forward about 100 thousands of an inch so it’s more in line to an actual Mauser. Trigger and hammer still functions as it should as well.![]()
I did cut such a slot with a Dremel, but only long enough for the existing front tip of the rails to lock into. I used 199 High Speed Cutter bit, which is shaped kind of like a cutting wheel. It was just wide enough to fit in there and do the job.The only way I could eliminate the screw entirely would be if I could machine slots in the upper receiver to accept rails I would somehow add to the lower, like how a real Mauser/MGC assembles.

It would be awesome if you could make full rails though!

I did also scratch-build a new hammer out of a block of aluminium, with sheet metal sides glued on. My upper is even further forward and I wanted a longer hammer anyway.
