Good catch. In my opinion, that's definitely a typo and it should be foot pounds.
Just for a point of comparison, my personal notes (summarizing information from the Colt Factory Armorer's Manual) say this:
"carbine buffer tube castle nut - using tool #2, 38-42 ft-lbs (dry)
rifle buffer tube - using tool #1 (in-line), 35-39 ft-lbs (dry)"
Of course, this gets back to the issue of what exact tools are used, and what the extension lengths and orientations are . . . If you really want, I can try to dig up a picture of them from the Colt manual. However, if you use the tool in the U.S. military manual linked in my post above, and use foot pounds instead of inch pounds, I am sure it will work out fine.
