The combat shotgun is a weapon in Fallout 4.

Characteristics[]

FO4 combat shotgun expanded

Combat shotgun expanded

The combat shotgun by default utilizes an 8 round box magazine but can be upgraded with a 12 round extended magazine or a 32 round drum magazine. The weapon is semi-automatic and in being a magazine fed gun, it does well in clearing out rooms and ripping apart enemies at close range. As indicated by the metal stamping on the weapon's bolt, the combat shotgun is chambered for 12 gauge shotgun shells. Each shell holds 8 (shot) pellets by default.

The combat shotgun can, however, be upgraded to be a fully automatic weapon at the expense of reduced range (in contrast to other weapons where fully automatic modification mainly reduces damage per shot and only has a small effect on the range). But the automatic receiver fires barely faster than (manually) rapid-firing the semi-automatic version. In fact, the hair trigger and advanced semi-auto receivers fire faster than the various automatic receivers, apart from the rapid automatic receiver.

Like double-barreled shotguns, combat shotguns suffer very severe damage penalties when fired outside of the listed range. The range-based damage penalties are five times greater than for other types of weapons. This is in addition to the consequences of pellet spread at range, which will cause more pellets to miss as the range increases.

On the plus side, when hip firing outside of V.A.T.S., unlike other weapons, shotguns suffer no penalty to the aiming reticle size when moving the weapon laterally. This is similar to the effect of finned barrels on pipe guns.

Notes[]

  • Combat shotguns with the two-shot legendary modified causes it to fire 7x2=14 projectiles, instead of the usual 7+1=8 projectiles.
  • Applying the advanced receiver adds an extra projectile per shot.
  • When equipped with a drum magazine, full stock, front sight ring, long barrel, and compensator, this weapon closely resembles the combat shotgun seen in Fallout 3. The only major difference is the placement of the magazine, which in Fallout 3 was placed in front of the ejection port.
  • Because the bleed damage is applied per projectile, a combat shotgun with the "Wounding" prefix inflicts massive damage per shot. The bleed damage will continue to stack with successive shots. With an advanced receiver, the weapon will deal 200 additional damage per shot over 5 seconds, if all projectiles hit the target.
  • The automatic receiver fires just one round in V.A.T.S., with no increase in damage compared to the single-shot receiver, while also adding a 25% increased cost to action point usage.
  • The combat shotgun and combat rifle share nearly identical models, with only a few differences.
  • When equipped with a bayonet and short barrel, the bayonet's model will clip through the shotgun's handguard.

Bugs[]

  • [Platforms needed] The damage of the explosive legendary variant of the combat shotgun is labeled wrong, while V.A.T.S. adds 15 damage to the total damage, the added damage is actually increased per pellet (7 pellets*15=105 Base, 120 W/ advanced receiver. Ranking up the Demolition Expert perk increases the explosive damage independently from direct hit damage). [verified]
  • [Platforms needed] The glow front sight ring does not appear in the Sights tab unless a front sight ring is placed in the player's inventory or a workbench, although it has no requirements and cannot be installed. This is because it is incomplete due to an oversight. It has no associated Construction Object, which determines the requirements to craft it, and shares a world object model with the front sight ring. The front sight ring's world object is called glow front sight ring, but it will only allow the installation of the front sight ring.[verification overdue]
