Helldivers 2 is a chaotic, high-stakes co-op shooter where every bit of performance counts. Whether you're mowing through bug hordes or holding your ground against automatons, having the right weapon attachments can drastically improve your effectiveness on the battlefield. With the game offering more tactical depth than ever before, many seasoned players have begun fine-tuning their loadouts to match specific mission types or enemy threats.

Here are 13 weapon attachments that can give you a serious edge in Helldivers 2.

1. Muzzle Brake

If you're using high-caliber weapons like the Diligence Counter-Sniper or Liberator Penetrator, a muzzle brake significantly reduces vertical recoil. This is especially useful for precise follow-up shots in tense encounters.

2. Red Dot Sight

For those who prefer fast target acquisition, the Red Dot Sight is a game-changer. It doesn't offer zoom, but the clearer reticle and faster ADS speed make it a staple on SMGs and assault rifles.

3. Reflex Sight

Similar to the Red Dot but with slightly better peripheral vision. Great for players who want situational awareness while still benefiting from a clean optic.

4. Suppressor

While not always necessary, the suppressor can help in stealth-oriented missions or in the early stages of enemy contact where avoiding detection can buy your squad valuable time.

5. Extended Magazine

More bullets before reloading means more uptime during fights. Particularly helpful for weapons like the Breaker shotgun or the Liberator carbine, where every second counts during swarm attacks.

6. Recoil Pad

This underappreciated attachment helps with sustained fire stability. It shines in missions with long engagements, especially when paired with light machine guns.

7. Thermal Scope

In night missions or against cloaked enemies, the thermal scope provides a major visibility advantage. It's also helpful for spotting threats through smoke or environmental clutter.

8. Flashlight Attachment

You might laugh until you play a mission in complete darkness or low-visibility biomes. A flashlight attachment can help spot mines, bugs, or interactables that would otherwise be missed.

9. Quick Swap Grip

Speeds up weapon switching — a critical boost when transitioning between your primary and support weapons under pressure. Ideal for players running close-quarters builds with backup sidearms.

10. Laser Sight

Perfect for hip-fire builds, especially when using SMGs or shotguns. The laser gives a good sense of aim without the need to ADS, keeping your field of view wide.

11. Armor-Piercing Ammo

Technically more of an ammo modification, this attachment punches through heavier armored enemies. Combine it with high-precision rifles or the new Helldiver-issued Diligence series for best results.

12. Compensator

Another recoil control tool, but with a horizontal emphasis. Great for automatic weapons where you need to maintain accuracy during long bursts.

13. Angled Foregrip

Enhances aim stability and speeds up ADS transitions slightly. A solid all-rounder for players who want balanced control improvements across a variety of weapons.

Bonus Tip: Maximize Loadout Customization with Resources

Many of these attachments are unlocked using in-game progression, and some are tied to reward trees where Helldivers 2 medals play a key role. Efficiently earning and spending these medals is crucial if you want to optimize your build quickly. And if you're looking to accelerate your progress or expand your customization options, some players choose to buy Helldivers 2 Super Credits to access premium gear faster. U4GM is one of the community-recommended places for this, offering a fast and straightforward service trusted by many veteran Helldivers.

Remember, no attachment is universally best — your choice should complement your squad's strategy, your personal playstyle, and the mission objectives. Test different combinations, and don’t be afraid to adapt between drops.
