Does Magura make a LHRB system?

First off all, It's just a overpriced "hope" MTB brake master with a Rekluse logo.

Second, is the worst part, the dual action is optained by changing the lid of the original foot operated master to a new Rekluse lid with a thread to fit the brakeline from the LHRB.

That means when you use the LHRB you pressurize the original master from the top, and the brakefluid reservoir is NOT designed to take that kind of pressure!!

My friend fit the system on his GG 300 and it was actually working good, untill he while braking, heard a loud "POP" and the LHRB lost all pressure and his right boot was soked in brakefluid, the level check window in the foot master was gone leaving him with a big hole in his rear master..
I have heard this exact same thing before.
There is a lot of discussion about it on KTM Talk.

I have not seen this in the flesh, but...
Of course the rear master cylinder isn't designed to take the brake pressure in its reservoir (window and all), and I do not think the Rekluse design intends to use it that way either. There should be a o-ring at the bottom of the part that you insert into the rear master cylinder. At least this was the case with the previous dual action design (where you used the clutch master for the rear brake). This o-ring seals off the pressure, so that the pressure from the left hand master cylinder is routed into the rear master cylinder's high pressure circuit.
Could it be that the o-ring is missing or leaking, or that the length of the insert is wrong for the actual rear master cylinder?

I have been playing with the idea of building a similar system for my bike, so if you could give me a link to the Hope (or other make) radial master cylinder that Rekluse use, I would be grateful.

It's actually a "Hayes" lever. Google Hayes trail disc brake. They have several version trail, pro and stroker and you can choose black or white also. I went with a white to be a bit different . Plan is to have a custom braided line and fitting eliminating the rear brake lever(tired of replacing them)

The Rekluse install video does show a rubber oring for fitment on the bottom of the brake reservoir.

I will take a better look at my friends system, maybe he installed it wrong?

It's a "Hayes" not a "Hope" master, rekluse are using, The Stroker Trail master:

Good find on the Hayes Mtn Bike master cylinder.

I really like the slim style of this and how it does not take up much space at all.

But my concern is that it will not be able to operate my new LHRB setup that uses a daul piston KTM 950 Brembo Rear Caliper. I am currently using a KTM Brembo Clutch Master Cylinder to operate my caliper. It provides plenty of braking power that only a slight grip of the lever and the brakes are there! I currently still have my Magura clutch installed but it makes for a very messy left side of my handlebars. I honestly don't think I have a need for my clutch but am still keeping it for a safety precaution...

To answer your question.
Yes they do. And so does Brembo.
They are made to be used on stunt bikes. But with this type you have to add a small brake fluid reservoir and they are very expensive.

rekluse installs an 1/8" spacer to increase the fluid capacity in the Hayes

I like that caliper! I'll take a look at your link for the Magura master cylinders.
