Most, if not all, of the M1 Carbine kits disappeared about two years ago. The CMP flooded the markets with new carbines, and kindled a new generation of "carbine collectors" who quickly learned that they could buy carbine kits, sell the desireable parts for about 3X what the kit cost. There were a bunch of companies that bought kits, and parted them out as well. With stocks bringing $150+, bolts commanding $100+, barrels bringing $150+, and trigger housings holding steady at $75+, not including small parts (recoil springs, operating slides, etc.) you could pay $400 for a kit, and quickly turn $500-$600.
