I would imagine the idea is for a relatively easy conversion.... You don't even need to completely disassemble the Disco, just remove the front fill fitting and replace it with the one in the kit.... Even the gauge stays in place.... The mod to the stock is the hardest part, and that would happen with a larger tube also....

In comparing the dual tube setup to an MRod tube, the dual tube is about 250cc total with a 2000 psi fill pressure, while the MRod is 215 cc and you fill to up to 3000.... If you fit stronger screws in the Disco valve, then you can fill to a higher pressure, of course.... and by doing that, you can get MRod performance from the Disco....

The twin tube Korean rifles have a good following in the USA, and so the concept is already well accepted.... When you consider that the Disco Double will still be a couple of pounds lighter than an MRod.... I think it will make a heck of a good conversion....
