Hek

"The HEK is a powerful shotgun that fires its shots with a tight spread, making it efficient at medium range as long as its strong recoil is properly managed."

- In-Game Description

The Hek is a shotgun that deals very high damage in a narrower cone compared to other shotguns. Presumably of Grineer design, the Hek trades subtlety and ammo capacity for raw firepower.

Characteristics
Advantages:
 * High damage.
 * Narrowest pellet cone of all shotguns.
 * Fastest reloading time of all shotguns.
 * Inflicts the most damage per shot of all shotguns.
 * Longest range of all shotguns.
 * Least damage falloff of all shotguns.
 * Infested Runners don't explode on death when killed by the projectiles of this weapon.
 * 100% stagger on Infested Ancients.

Disadvantages:
 * No polarity mod slots.
 * Very small base magazine size.
 * Like all shotguns, this weapon is less effective against the Grineer without armor piercing mods.
 * Requires Mastery rank 4 to unlock and purchase.
 * Extremely inefficient beyond medium range.
 * May miss enemies at point-blank range due to the length of the barrels.
 * Tight pellet spread may make close-quarter combat difficult.

Acquisition
The Hek can be purchased for  225 or the blueprint for  25,000 upon reaching Mastery Rank 4.

Tips

 * Very effective against the Infested, especially when used with fire mods.
 * Climbing mastery ranks requires leveling many weapons. Mastery rank 4 is equivalent to leveling 2 warframes to level 25 and 10 different weapons to max rank (Or 3 Warframes and 5 weapons to Rank 30).
 * Ammo Stock mod rank 0 (+10%) adds no extra rounds to the magazine. Rank 1 (+20%) adds one round to the magazine (for a total 5) and Rank 3 (+40%) adds two (for a total 6). There is no need to upgrade the mod further as no additional rounds will be gained.

Trivia

 * This weapon is used by Councilor Vay Hek. This has caused speculation as to whether the Councilor himself is the shotgun's namesake, or otherwise responsible for designing/commissioning it.
