Hey .30 Carbine fans! Anybody heard about this?

I've seen these guys around for a few years. They had a neat looking .22 Magnum that they've now made in 5.7x28 (which I thought was a no brainer), but now, they make a series of rifles in .22 Mag, 5.7x28, and .30 Carbine, which I think is exciting.
I cast for my beloved Underwood M1, but the gas system is notorious for Lead build up (although it hasn't been a problem for me so far). A modern, "delayed blowback" (no gas system, I assume) rifle in .30 Carbine that takes cheap and plentiful M1 Carbine magazines, that weighs about the same as an M1 and costs about the same as a Mil-Surp GI or a new cast clone? Yes, please!
