hmmm... since out country is less likely to have evil scientists plotting and developing zombie viruses, I reckon they'd first come into the country via Airports or Marinas.

Modifying an AK-47/74/1xx with a silencer and some heatsinks with belt fed ammo might work since in a post apocalyptic scenario, you can't afford weapon jams and cleaning the gun. silencer is there so that it won't attract attention from them zombies :D

to survive, one must conceal and since the dead have compromised vision, their senses are mostly auditory and olfactory. hence, one must cover himself with odor masking and be silent.
