When it comes to surviving the harsh wasteland of Fallout 76, having the right weapon mods can make all the difference. Whether you're taking on Scorchbeasts, clearing out Super Mutant camps, or just exploring Appalachia, optimizing your gear is key. To help you get the most out of your arsenal, we’ve compiled a list of the 20 best mods to enhance your weapon performance.

1. Hardened Receiver (Ballistic Weapons)

A staple for any ballistic weapon, the Hardened Receiver increases base damage significantly. If you're running a rifle or heavy gun build, this is a must-have.

2. Aligned Automatic Barrel (Commando Builds)

For players who prefer automatic weapons, the Aligned Automatic Barrel improves recoil control and fire rate, making it ideal for VATS-focused builds.

3. Stinging Magazine (Handmade Rifle)

This magazine mod adds armor penetration and increases ammo capacity, giving your Handmade Rifle a serious edge in firefights.

4. Prime Receiver (Energy/Heavy Weapons)

If you're up against high-level enemies, the Prime Receiver boosts damage and allows you to use ultracite ammo—perfect for endgame content.

5. Suppressor (Stealth Builds)

A suppressor is essential for stealth snipers. It keeps you hidden while dealing critical damage from the shadows.

6. Beam Splitter (Laser Weapons)

Turning your laser weapon into a shotgun-like spread, the Beam Splitter is devastating at close range.

7. Calibrated Shocks (Power Armor - Indirect Weapon Boost)

While not a direct weapon mod, Calibrated Shocks increase carry weight, letting you haul more Fallout 76 items for sale or loot without slowing down.

8. Reflex Sight (VATS Efficiency)

Improving VATS accuracy and AP cost, the Reflex Sight is a top pick for players who rely on critical hits.

9. Extended Barrel (Range Boost)

For rifles and pistols, the Extended Barrel increases range and accuracy, making it easier to pick off enemies from a distance.

10. Compensator (Recoil Reduction)

If you struggle with weapon kick, the Compensator helps keep your shots on target.

11. Drum Magazine (Heavy Guns SMGs)

More ammo means less reloading—essential for heavy gunners and run-and-gun playstyles.

12. True Long Barrel (Precision Rifles)

A variant of the Extended Barrel, this mod offers even better stability for precision shooters.

13. Glow Sights (Low-Light Combat)

These sights highlight enemies in the dark, giving you an advantage in dimly lit areas.

14. Bayonet (Melee Hybrid Builds)

Adding a bayonet to your rifle gives you a melee option when enemies get too close.

15. Scorched Killer Receiver (Vs. Scorched)

As the name suggests, this mod increases damage against Scorched enemies—great for Fallout 76’s endgame.

16. Recoil-Stock (Shotguns SMGs)

Reduces recoil dramatically, making follow-up shots much easier to land.

Another great armor-piercing option, this mod works well on rifles and pistols.

If you prefer speed over raw damage, this mod decreases firing delay.

Increases weapon durability while also improving recoil control—great for long expeditions.

Final Thoughts

Finding the right mods can take time, especially if you're missing specific plans. Some players opt to buy Fallout 76 caps to speed up the process, while others trade for mods directly. Sites like U4GM can be a resource for those looking to acquire rare mods or gear efficiently.
