Every Attachment Explained

Barrel stabilisers: When attached to a compatible weapon, a barrel stabiliser will reduce recoil. The recoil reduction is higher the higher level of the barrel stabiliser (Levels 1-4 available), and Level 4 barrel stabilisers simultaneously reduce muzzle flash

Optics: There are many optics, including:

1x HCOG Classic 

1x HOLO 

1x Digital Threat 

2x HCOG Bruiser 

1x-2x HOLO Variable 

3x HCOG Classic 

3x-4x Variable AOG 

6x Sniper

4x-8x Variable Sniper 

6x-10x Variable Digital Threat Sniper

You can experiment with them in Firing Range to see how each optic changes your ADS, and:

- a 1x scope magnifies your ADS by 1

- a 2x scope magnifies your ADS by 2

- a 3x scope magnifies your scope by 3

and so on

- Variable scopes let you change the magnification of your ADS

- Digital Threats highlight enemies in red

Extended Mags: Increase how many bullets you can fire before reloading. Can be found in Level 1-3. 

Extended Light Mags do this for light ammo guns.

Extended Heavy Mags do this for heavy ammo guns.

Extended Energy Mags do this for energy ammo guns.

Extended Sniper Mags do this for sniper ammo guns.

Stocks: There are Standard Stocks and Sniper Stocks. Found in Levels 1-3

Standard Stocks can be attached to all LMGs, SMGs and Assault Rifles. They reduce the aim drift of your gun and reduce the time it takes to pull it out

Sniper Stocks do this for snipers

Hop-Ups

Skullpiercer Rifling: Valid for the Longbow DMR and Wingman. Increases the weapon's headshot damage.

Anvil Receiver: Vaulted. Was valid for the R-301 Carbine and VK47 Flatline. Increased semi-auto damage, but the single fire consumed two ammo per bullet and rate of fire was reduced.

Turbocharger: Vaulted (returning in Season 6). Was valid for the HAVOC Rifle and Devotion LMG. For the HAVOC Rifle it removed the need to charge before firing and for the Devotion LMG it significantly reduced the ramp-up time of the rate of fire.

Double Tap Trigger: Valid for the G7 Scout and Eva-8 Auto. Grants an alternative burst fire mode. As the name suggests, two shots can be fired per trigger pull.

Hammerpoint Rounds: Valid for the P2020 and Mozambique Shotgun. Greatly increases damage to unshielded targets.

Precision Choke: Valid for the Triple Take. Was valid for the Peacekeeper. Greatly reduces the gun's bullet spread by aiming down sights, up to three levels. The weapon loses the charge if the player stops aiming down sights.

Selectfire Receiver: Valid for the HAVOC Rifle and Prowler Burst PDW. Enables an alternative fire mode: it allows the Prowler to fire full auto and allows the HAVOC to fire single, hitscan lasers

Disruptor Rounds: Vaulted. Was valid for the Alternator SMG and RE-45 Auto. Increased damage to shielded targets.
