The bolts can normally be dropped in if the chamber and receiver are within spec, but that should be verified, IMHO. They are not, however, blowback operated, as most .22 rimfire semi-auto systems are, for example. The M1 bolts are gas-operated rotating bolt actions, operated by a short-stroke gas piston system, usually called a tappet and slide system.
