Which weapon is blowback operated?

Explanation:
Blowback operation relies on the pressure of the fired round to drive the bolt rearward, without a locked breech, with the bolt and spring then cycling the next round. The MK19 is designed as a blowback-operated weapon, typically firing from an open bolt and feeding from a belt. Its mechanism uses the cartridge pressure to push the bolt back, extract and eject the spent casing, then chamber the next round as the bolt springs forward. The other weapons listed use different cycling systems—gas-operated or recoil-operated with locking mechanisms—so they don’t use blowback.
