Fallout 76 Automatic Rifles Build

Automatic Rifles are hands down some of the most powerful weapons in the game, if not THE most powerful. Trying to grab a strong Handmade rifle, slapping together a couple perk cards, and you can be an absolute V.A.T.S. Critical shot hitting machine, with very few breaks for your enemies to breathe. 

Today, we introduce Prowler’s V.A.T.S. Critical focused Automatic Rifle build in Fallout 76.

Perk Cards of Choice (SOLO)

Fallout 76 Auto Rifles Build

If you play solo or in a team, you can deal pretty close to the same amount of damage, but if you DO play in a team, the bigger the team the better. 


In the Case of Automatic Rifles, there are ALWAYS better Legendary’s than others, as well as weapons in general. Assault rifles, Laser Rifles, anything automatic can be used well, but Automatic Handmade’s (In the current version of the game) are typically the most sought after and well rounded damage dealing Automatic Rifles. 

In that case, here are the Legendary effects you’d like to find on your Legendary Automatic Rifle.

Legendary Main Effects:

Anti-Armor: Ignores 50% of an Enemies armor

Junkie’s: Deals greater damage the more negative effects you have

Bloodied: (Deals greater damage when you’re health is low)

Two Shot: Fires a second projectile equal to 25% max damage every shot

Legendary Major Effects:

25% Faster Fire Rate

+50 Limb Damage


V.A.T.S. Critical Shots deal 50% more damage

+33% V.A.T.S. Hit Chance

Legendary Minor Effects:

25% Less V.A.T.S. Action Point Cost

15% Faster Reload Speed

Your V.A.T.S. Crit Meter fills 15% Faster

Rolling an Automatic Handmade with any of these Perks is going to serve you well, but obviously there are better perks than others. The BEST Legendary you could possibly run for this build would be either a “Bloodied – Explosive – 15% Faster Crit” Handmade, or a “Bloodied – 25% FFR – 25% V.A.T.S. AP Cost” Handmade. Rolling EITHER of those would be an absolute miracle, but just because they aren’t 100% one of those, doesn’t mean it’s bad. 

The other recommended weapons to look out for would be a Fixer with 25% Less Action Point Cost. This is probably one of the most sought after weapons in the game, and can have 4 legendary effects instead of 3.

Weapon Mods

As for Weapon mods, it’s fairly typical when it comes to using any Rifles. You’ll want to attach an:

  • Automatic Receiver (Preferably anything that adds Crit Damage)
  • Aligned Barrel
  • Forcedful/Aligned Stock
  • Fast Reloading Magazine
  • Red Dot Sight

These Attachments will help keep you in CONSTANT V.A.T.S. able to continuously swap from enemy to enemy.


Armor choice is VERY Important, especially when using a Bloodied build. You can die rather quickly when your health is continuously below 20%, which means you need some tough armor to help keep you alive.

That’s why this build highly recommends using Bolstering Armor, which is essential super protection while your so low of health. Using Combat or Marine armor with the Bolstering Main Legendary effect, you can soak up a TON of damage. Next up, you’ll want to focus on getting some two or three star legendary pieces, hopefully including things like:

+1 Perception 

+1 Agility

+1 Endurance

Now remember, ANY Legendary perk that lessens the carry weight of items is incredibly important, and is a must have when using builds that are built on holding tens of thousands of rounds for 5.56 firing weapons. 

The next Armor set recommended is the Chinese Stealth Suit which is essentially the best stealth armor you can get in the game. This allows you to turn invisible the moment you enter crouch, and you can walk and shoot to your hearts content. 


As an Automatic Rifle build, you want to try and focus on getting your Critical damage shots and damage in general so high that everything dies instantly. Try to focus on getting these specific build buffs.


Remember, you have BOTH Class Freak AND Starched Genes on to fully utilize the benefits of mutations and take away their negative effects.

Adrenal Reaction: Increased Damage Output at low health. Without Class Freak, this comes at a cost of 50 Health.

Marsupial: +20 Carry Weight, and you can jump much higher. The carry weight is a HUGE bonus in this game. Without Class Freak, this comes at the cost of 4 Intelligence

Speed Demon: +20% run and sprint speed, +30% faster reload speed. The reload speed with a Heavy Gunner build is a MUST HAVE, as they can take a LONG time to fully reload, and the Gauss Minigun is no exception. Without Class Freak, this comes at a cost of 50% more hunger and thirst while moving.

Eagle Eyes: Here you find yourself at a BIT of a dilemma, as your strength is now completely wiped off the face of the planet BUT your critical damage is boosted greatly. Even though you won’t be too strong anymore, you’ll be dealing better crit damage than ever before.

Healing Factor: With Healing factor on, you have quite a bit less to worry about with having a lower health build for Bloodied or Berserker’s. This is just an added bonus to help you stay alive.

Scaly Skin: Damage and Energy Resistance +50 at the cost of 50 Action Points.


Once again, really easy to find and make, these are the drinks you want to spam create in order to pop them as often as possible, plus the ingredients don’t weigh you down.

Tarberry Juice: 15% Water & +120 AP

Steeped Thistle Tea & Sweet Mutfruit Tea: +25% Water & +20% Crit Damage

Melon Juice: 15% Water & +0.08% Health Regen


Everyone’s favorite Fallout meal of the day. Here are the drugs you want to bulk up on, just to always boost your build to the most powerful it can possibly be.

Overdrive: +15% Damage, +25% Critical Chance. Of course, it doesn’t last for very long, so it’s good to use it sparingly.

The Rundown

This Automatic Rifle V.A.T.S. Crit Build guarantees that, if used correctly, you will be able to almost instantly kill any enemy within a matter of seconds, minus the bigger end game bosses… which is can still solo quite easily if you keep your distance. Make sure that you play carefully if you’re a Bloodied Build user, and take advantage of all the hiding locations you can, as this build relies heavily on killing everything from stealth.

If you want to check out the build for yourself, or maybe even customize it to your own liking, I would highly recommend checking out NukesDragons “You are SPECIAL” Character Builder, it’s super quick and easy to use.
