5.7 Johnson and M1 Carbine

[RCS]

I am certain that I posted this short story before: soon after the 5,7 and 22 Carbine Wildcat cartridges found their way into surplus M1 carbines a gunsmith offered a "kit" (not cheap) to convert your carbine in a 7,62x33 mm Kurz caliber using 308 Win cases shortened to fit the carbine magazine with a 110 gr bullet. This kit, as I remember, included a longer barrel with the gas port moved forward, the slide was modified and bolt face opened-up completely, This also included a long recoil spring. A friend asked me to help him complete this conversion on a cheap DCM carbine and I told him that I wanted no part of this project. my photo shows the 5,7mm carbine and 30 Kurz cartridges (my kurz cartridge photo was also used by Cartridges of the World some years ago)

The 7,92x33 still lives as I saw a conversion of the AR-15 to use this cartridge, custom 8mm barrel with kurz chamber plus gages (around $800 ?) and still without a working magazine !
