M-1 paratrooper

Sale price: $1,560
"To the Greatest Generation, and even their kids, the M-1 defined the word 'rifle,'" wrote the late Chris Kyle, the deadliest sniper in U.S. history, in his posthumously published "American Guns." M-1s typically have wooden stocks, so this extra-portable paratrooper model, with a folding metal stock, is quite rare.
