VATS in Fallout 76 has been completely reworked for Patch 62 (Sept 2025). Instead of starting with a low hit chance and building upward, the new system begins at the maximum value (95%) and then reduces that number based on weapon stats, distance, visibility, and perks.

This update aims to make VATS behave more like real combat, where weapon handling, positioning, and line of sight matter as much as your SPECIAL stats.

This guide will explain the following and how each affects your VATS hit chance:

Distance & Weapon Range
Visibility (Line of Sight)
Body Part Difficulty
Recoil
Cone of Fire (Spread)
Fire Rate
VATS Accuracy Stat
Perception
Mods & Perks

Distance & Weapon Range

Distance is one of the most important factors in determining VATS hit chance. Every weapon in Fallout 76 has a range stat, measured in feet, that defines how far it can fire effectively. This stat controls both how accurate your shots are in VATS and how much damage the weapon deals over distance.

Hit Chance and Distance

At close range, VATS applies fewer penalties. Being within about half of your weapon’s listed range gives you a higher chance to hit, and smaller penalties from spread and recoil.
Once you move beyond half range, hit chance steadily begins to drop. The farther away the target, the lower the percentage will fall, even if you’re aiming at a large body part.
At your weapon’s maximum range, VATS hit chance may drop to 0%, no matter how well you aim.

Damage Falloff In addition to accuracy, damage also decreases as distance increases:

At maximum range, weapons deal 50% of their base damage.
At double their range, weapons deal only 10% of their base damage.
This applies to all combat — hipfire, aiming down sights, and VATS.

Example A rifle with a 120-foot range:

At 60 feet or less (half range), you’ll have strong accuracy and full base damage.
At 90 feet, your hit chance will begin to decline, though you’ll still deal close to full damage.
At 120 feet, hit chance may drop to zero, and damage will be halved.
At 240 feet (double range), even if you hit, damage will be reduced to just 10%.

How to Improve

Use longer barrels or range-focused mods to push accuracy further.
Avoid short-range weapons (shotguns, SMGs) in open combat where VATS accuracy will collapse.
Keep targets within half your weapon’s range to get the best balance of accuracy and damage.

Visibility (Line of Sight)

VATS no longer allows you to target enemy body parts that you cannot clearly see. In the old system, players could sometimes select hidden or obstructed limbs — such as aiming at the back of an enemy while standing in front of them — but this has been corrected.

How It Works

VATS checks line of sight before letting you select a body part.
If a limb or weak spot is behind cover, terrain, or the enemy’s own body, it cannot be targeted.
Shots cannot be forced through walls, rocks, or obstructions using VATS targeting.

Gameplay Impact

Enemies using cover are more difficult to hit because fewer body parts are exposed.
Large enemies (such as the Scorchbeast Queen) can no longer be targeted through their torso to reach a weak spot on the other side.
Specific mechanics, such as shielded parts on certain bosses, must now be approached from the correct angle.

How to Improve

Reposition during combat to gain a clear line of sight on the body part you want to hit.
Use vertical positioning (jetpacks, high ground, ledges) to expose hidden parts of large enemies.
Flank enemies who are hiding behind obstacles to open up new targeting options.

Body Part Difficulty

Not all targets are equally easy to hit in VATS. The system assigns different base hit chances depending on the size and visibility of each body part. Larger areas, such as torsos, are easier to lock onto, while smaller parts like heads or limbs carry heavier accuracy penalties.

How It Works

Torso – Highest base hit chance.
Limbs (arms, legs) – Moderate penalties, especially at longer ranges.
Head and other small targets – Lowest base hit chance, often requiring higher accuracy to land consistently.

Gameplay Impact

Precision targeting (heads, weak spots, limbs) will usually show a lower hit chance than the torso, even at close range.
At longer ranges, limb and head targeting may drop close to zero, even when torso shots remain viable.
For builds that rely on crippling enemies or landing headshots, this means VATS accuracy must be improved through perks, mods, or buffs.

How to Improve

Use the Concentrated Fire perk to increase hit chance on a selected body part with each consecutive VATS shot.
Increase VATS Accuracy stat through mods and perks to improve baseline precision.
Raise Perception to help reduce penalties when targeting small body parts, particularly at mid-range.

Recoil

Recoil refers to the kick of your weapon each time it fires. In VATS, recoil makes it harder for the system to stay locked on target during follow-up shots. The more the weapon moves between shots, the lower your hit chance becomes.

How It Works

Each shot pushes your weapon’s aim off target.
VATS attempts to correct this movement, but heavy recoil lowers the chance of landing the next shot.
Recoil builds up during sustained fire, especially with automatic or high–rate-of-fire weapons.
Semi-auto weapons with strong kick (e.g. combat rifles, plasma guns) are also affected, though less frequently.

Gameplay Impact

Automatic rifles, heavy weapons, and burst-fire receivers lose accuracy quickly as recoil accumulates.
High fire rates magnify the problem, since VATS has less time to adjust between shots.
Short, controlled bursts remain more accurate than holding the trigger down.

How to Improve

Equip True or Stabilized grips and barrels to reduce recoil.
Use muzzle mods like compensators or muzzle brakes to stabilize firing patterns.
Choose semi-auto or slower-firing receivers when building a VATS-focused weapon.
Combine with perks that indirectly reduce spread or recoil for greater consistency.

Cone of Fire (Weapon Spread)

Every weapon in Fallout 76 has a hidden cone of fire — an invisible arc that defines how tightly or widely bullets spread when fired. VATS uses this value to estimate how predictable your weapon is. The wider the cone, the more uncertain VATS becomes about where shots will land, and the lower your displayed hit chance.

How It Works

Weapons with a tight cone (sniper rifles, semi-auto pistols) keep shots closer to the center, making them more reliable in VATS.
Weapons with a wide cone (SMGs, shotguns, fast automatics) scatter bullets, so VATS reduces the hit chance to reflect that unpredictability.
Spread grows during sustained automatic fire, making accuracy worse with each shot until the cone resets.
Multi-projectile weapons (such as the Pepper Shaker or Enclave Plasma Gun with splitters) also suffer heavily from spread penalties.

Gameplay Impact

Close-range weapons with wide spread may still perform well at point-blank range, where VATS penalties are reduced.
At medium to long ranges, high-spread weapons quickly lose hit chance, even on large targets like torsos.
Automatic weapons show noticeable accuracy loss in VATS when fired in long bursts.

How to Improve

Install True mods (−15% base spread, −15% ADS spread).
Use Stabilized mods (−5% base spread, −25% max spread, −15% hipfire spread).
Raise Perception to reduce how severely spread affects accuracy.
Select perk cards that tighten spread or indirectly improve accuracy with automatic weapons.

Fire Rate

Fire rate measures how quickly a weapon can fire successive shots. In VATS, very fast-firing weapons are more difficult for the system to predict accurately. While fire rate itself isn’t directly used in the hit chance formula, it interacts with recoil and cone of fire, meaning the faster a weapon shoots, the quicker those penalties stack up.

How It Works

Each shot in VATS is tracked individually.
If the weapon fires too quickly, VATS has less time to correct aim between shots.
Sustained high fire rates push weapons to their maximum recoil and spread values much faster, further lowering hit chance.
Semi-auto and burst fire weapons avoid this problem, as the system can reset between shots or bursts.

Gameplay Impact

Fast SMGs, automatic rifles, and energy weapons lose accuracy rapidly in VATS during long bursts.
Short bursts are usually more accurate than holding the trigger.
Semi-auto rifles and pistols tend to perform better in VATS due to slower, more predictable firing patterns.

How to Improve

Choose semi-auto, burst, or slower full-auto receivers for VATS-focused builds.
Avoid stacking fire rate bonuses if your goal is precision rather than raw damage.
Pair high-fire-rate weapons with recoil-reducing and spread-reducing mods to keep accuracy manageable.

VATS Accuracy

In addition to visible stats like Range and Fire Rate, every weapon in Fallout 76 has a hidden VATS Accuracy value. This stat determines your baseline hit chance before any penalties from distance, spread, recoil, or body part size are applied. A higher VATS Accuracy makes it easier to reach the 95% cap, even when other conditions are less than ideal.

How It Works

VATS Accuracy raises your starting hit chance across all body parts.
It softens the impact of minor penalties, such as small amounts of spread or moderate distance.
Weapons with high VATS Accuracy feel more consistent in targeting, especially when aiming for limbs or heads.

Gameplay Impact

Helps precision-focused builds that target heads or weak spots.
Makes mid-range combat more reliable, even without perfect positioning.
Benefits semi-auto or burst-fire weapons most, since their shots are naturally easier for VATS to track.

How to Improve

Equip weapon mods that specifically boost VATS Accuracy (such as glow sights).
Use perk cards that directly improve accuracy in VATS (e.g., Awareness, VATS Enhanced, Eye of the Hunter).
Combine with Perception buffs to raise your effective baseline even further.

Perception

Perception is one of the SPECIAL stats that directly influences VATS accuracy. It doesn’t guarantee a hit on its own, but it reduces penalties that come from weapon spread (cone of fire) and from fighting at longer ranges. The higher your Perception, the less harsh these penalties become — as long as you’re still within your weapon’s maximum range.

How It Works

Spread Penalties: With higher Perception, VATS is better at handling weapons with wide cones of fire. Bullets are treated as more predictable, so your hit chance doesn’t drop as steeply.
Range Penalties: Within your weapon’s listed range, Perception lessens the accuracy loss that occurs as you get farther from your target. Once you pass the maximum range, Perception no longer helps.

Gameplay Impact

Builds that rely on automatic weapons, SMGs, or shotguns benefit from higher Perception, since these weapons normally suffer from spread penalties.
Mid-range rifles are noticeably more accurate with higher Perception, especially when targeting limbs.
Limb and head targeting remain more consistent at medium distances.

How to Improve

Use food, drink, and chem buffs to increase Perception, especially when fighting at medium to long ranges.
Equip perk cards that scale with Perception or boost their effectiveness

Sweetwater Special Blend Breakdown

	Base	Mutation	Mutation + SIN	Party Girl/Boy Rank 1	Party Girl/Boy Rank 2
Sweetwater Special Blend	+2 Perception	+4 Perception	+5 Perception	+10 Perception	+15 Perception

Note: Sweetwater’s Special Blend cannot benefit from All Night Long if Party Boy/Girl is equipped. With Party Boy/Girl, the buff scales higher (+10 PER at Rank 2 or +15 PER at Rank 3) but only lasts 60 minutes. With All Night Long, the duration doubles to 120 minutes, but the buff caps at +5 PER (with Herbivore + Strange in Numbers).

Mods & Perks

While distance, spread, and recoil all reduce your VATS hit chance, weapon mods and perk cards provide the main ways to counteract these penalties. By improving weapon stability, tightening spread, or directly boosting VATS accuracy, the right setup can push your hit chance much closer to the 95% cap.

Weapon Mods

Barrels – Longer barrels extend weapon range, delaying both accuracy loss and damage falloff. Stub barrels improve handling at short range.
Sights – Glow sights are especially strong, as they both increase VATS accuracy and reduce AP cost by 20%. Front sight rings also help by lowering the maximum cone of fire.
Muzzles – Compensators reduce initial recoil and extend stability during bursts. Muzzle brakes reduce overall recoil and lateral drift, while suppressors slightly reduce recoil and also grant a +50% bonus to sneak attack damage.
Receivers – Hardened and Critical receivers increase damage but also raise AP cost and recoil, making them a tradeoff for VATS use. Ammo conversion mods follow the same logic: stronger ammo raises AP cost, weaker ammo lowers it. Prime receivers add damage but with penalties to recoil, fire rate, and AP efficiency.
Stocks & Grips – Aligned stocks and grips provide some of the best recoil control, directly helping VATS accuracy.

Careful receiver choice balances damage output against AP efficiency.

Key Points to Remember

Stay within half your weapon’s range for the best accuracy and damage.
Position yourself so targets are fully visible, VATS can’t hit what you can’t see.
Expect torsos to be easier to hit than heads or limbs, especially at distance.
Recoil and cone of fire grow worse in sustained fire, short bursts are more accurate.
Glow sights are best-in-slot for VATS builds, improving accuracy and reducing AP cost.
Aligned stocks/grips, compensators, and muzzle brakes provide the strongest stability boosts.
Perk Cards directly increase VATS accuracy.
Perception buffs improve reliability at mid-range and help offset spread-heavy weapons.
