Recommended Mods
Max ammo is very useful if not essential for Dual Vipers, as it drains ammo very fast, and Damage and Multishot mods are vital to improve bullet efficiency. Quickdraw is also advised as this weapon relies on reloading quite often. You also have a fair degree of choice to invest in either AP, fire or electricity mods for the slot and specialize Viper against one faction or another.
 * Trick Mag (Max Ammo+) or No Return (AP+)/ Elemental Damage on
 * Hornet Strike (Damage+), Barrel Diffusion (Multishot+)
 * Quickdraw (Reload Speed+)

INSANE DAMAGE  Focus on critical damage and critical chance, the twin vipers have a very high crit rate.
 * Barrel Diffusion ( Multishot )
 * Hornet Strike ( Damage % )
 * Pistol Gambit ( 120% crit chance )
 * Target Cracker ( 80% crit damage )
 * No Return ( AP )
 * Trick Mag ( max ammo )
 * Fire elemental for infested, Ice for grineer, shock for corpus.

With 120% crit strikes, you will crit at least every 2 shots. You will see yellow flying off of people.

When you add crit damage with a fire mod vs infested, you will easily see 300 damage crits flying out often.

Add No Return for grineer and ancient's and you will tear them down in seconds.
