Assault rifles and Launchers are the best weapon suitable for this class especially the Blaster and the AT4-CS.
If you have a Blaster, combine it with Critical Up and Accuracy Up to deal fatal damage. (make sure you have leveled up everything for best performance)
If you have an AT4/AT4-CS, combine it with Explosive Up and Nuclear Bomb to deal fatal damage against multiple enemies.
A good build for Rifleman would be:

Primary weapon: Blaster, secondary weapon: Dual Infinity Final, melee weapon: Katana or Master Combat Knife and any grenade.
Primary weapon: AT4/AT4-CS, secondary weapon: M79 Saw off or Dual Infinity Final, melee weapon: Katana or Master Combat Knife and any grenade.

Tankers are the main enemy to them.
If you are using Tanker, use a shotgun to stun them as stunned enemies are unable to shoot or move for a period of time.
If you are using Alice, use the MG36 with NHP: Spiritual and Auto Guard ability.

These weapons can be used by Riflemen:

Rifleman could use a several models of assault rifles, pistols, Grenade Launchers, rocket launchers and melee weapons only. Grenades are also usable.
Although some posters and the trailer show the rifleman armed with an XM8, it is unusable in the game.
This character is not available in Singapore/Malaysia, Indonesia, Vietnam and Counter-Strike Nexon: Zombies because Metal Arena is not released in these regions.
