Whether you’re facing down hordes of ARC machines or dueling other players, weapon attachments in ARC Raiders make a massive difference in performance. Attachments modify key stats like recoil, bullet spread, magazine size, aim speed, and even noise — yet the game itself doesn’t clearly explain what each one actually does or which ones are worth using.

In this guide, we break down the best attachments for every weapon in ARC Raiders, helping you maximize your firepower and handling in both PvE and PvP scenarios.

---------------------------------------------------------------

Rattler – Built for Controlled Bursts

The Rattler’s biggest weakness is dispersion, not recoil. After about five shots, its bloom expands rapidly, forcing a burst-fire playstyle. This weapon was clearly designed for players who dip in and out of cover.

Best setup:

Stable Stock (priority) – Improves dispersion recovery for burst firing 
Compensator – Reduces maximum bloom

Grips are unnecessary here, as recoil is already manageable. A compensator and green stock dramatically improve performance.

---------------------------------------------------------------

Pharaoh – Recoil Mods Are a Trap

Grips, stocks, and compensators are largely useless on the Pharaoh because you drop ADS after every shot anyway. Recoil doesn’t matter.

What does matter:

Silencer – Great utility and stealth 
Lightweight Stock – Massive ADS speed boost enables quick-scoping and faster weapon swaps 
Extended Barrel – Improves bullet velocity and effective range

The Pharaoh thrives on speed, not stability.

---------------------------------------------------------------

Kettle – Vertical Recoil Focus

The Kettle has manageable dispersion, so recoil reduction is the priority.

Recommended setup:

Muzzle Brake 
Vertical Grip 
Extended Magazine (important due to long reload)

A cheaper option is a gray stock and gray mag, but an extended magazine is highly recommended.

---------------------------------------------------------------

Stitcher – Close-Range Stability Matters

In close PvP fights, recoil control becomes crucial.

Best setup:

Epic Padded Stock – Extremely strong and affordable 
Extended Magazine – More bullets = better 
Angled Grip – Reduces horizontal recoil

Stable stocks usually don’t help Stitchers — except the padded stock, which is exceptional.

---------------------------------------------------------------

Shotguns (Toro) – Choke Above All

The Toro recovers bloom extremely fast, making stable stocks unnecessary.

Priority mods:

Shotgun Choke – Tightens spread and increases effective range 
Vertical Grip (only at higher levels) 
Extended Magazine

At level one, grips are unnecessary. A green choke alone is enough for a reliable shotgun.

---------------------------------------------------------------

Arpeggio – Loves Full Attachments

The Arpeggio benefits from almost everything.

Priority order:

Compensator 
Stable Stock 
Vertical Grip

Upgrading to at least level three is strongly recommended for consistency.

---------------------------------------------------------------

Anvil – Simple but Effective

With only one real mod slot, the choice is easy.

Best option:

Compensator

Alternatives:

Silencer (preferably blue) for stealth

Extended Barrel for range and projectile speed 
Green compensator remains the most balanced choice.

---------------------------------------------------------------

Beretta – Quiet and Efficient

The Beretta already has low recoil.

Recommended:

Blue Silencer (near silent) 
Green Magazine 
Upgrading beyond level two or three isn’t necessary.

---------------------------------------------------------------

Renegade – Stock First, Always

With at least a green stable stock, dispersion fully recovers between shots.

Optimal setup:

Stable Stock 
Muzzle Brake

Upgrading the Renegade is very impactful, especially at higher levels.

---------------------------------------------------------------

Torrene – Magazine and Fire Rate Win

Best setup:

Compensator 
Extended Magazine 
Kinetic Converter (optional) – Increases fire rate and damage output

No need for stable stocks. Level two or three upgrades are enough.

---------------------------------------------------------------

Osprey Sniper – Ignore Recoil Mods

Because ADS resets after every shot:

Grips, stocks, and compensators are useless

Best mods: Silencer

---------------------------------------------------------------

Volcano – Go All In or Don’t Use It

The Volcano has extreme recoil.

Required setup:

Shotgun Choke 
Angled Grip 
Extended Magazine 
Upgraded to at least level three

Level one Volcano is simply not worth using.

---------------------------------------------------------------

Hulk Slapper – Naked Is Best

Attachments and upgrades provide almost no benefit.

Best setup:

No attachments 
Level one

Save your resources.

---------------------------------------------------------------

Bobcat – One of the Best Weapons in the Game

Optimal setup:

Muzzle Brake 
Angled Grip 
Extended Magazine 
Padded Stock (optional)

Upgrading the Bobcat is extremely important — level three or higher is recommended.

---------------------------------------------------------------

Tempest – Recoil Over Dispersion

Instead of a compensator, focus on recoil control.

Best setup:

Muzzle Brake 
Vertical Grip 
Level two or three upgrade

Produces smooth, accurate burst fire.

---------------------------------------------------------------

Batatina – Fix the Feel

The Batatina suffers from awkward bullet velocity.

Recommended setup:

Stable Stock (priority) 
Extended Barrel 
Vertical Grip

Level two or three upgrades are sufficient.

Weapon performance in this game is heavily influenced by hidden mechanics like dispersion recovery, bloom behavior, and fire-rate interactions. Many attachments seem useful on paper but do nothing in practice.
