Attachment

The slots for attachments. From left to right: Barrel, Mag, Optic, Stock, and Hop-Up.

Attachments are items that can improve a weapon's stats.

There are 5 categories:

• Barrels reduce recoil.
• Mags increase magazine size.
  • Shotgun Bolts increase the rate of fire for shotguns. They are classified as mags even though they do not provide any magazine increase.
• Optics provide an optic to look through while aiming down sights.
• Stocks improve handling, reduce aim drift, and reduce reload time.
• Hop-Ups modify the weapons in unique ways.

The number of attachments a weapon can have varies from weapon to weapon. Some weapons can have up to five attachments, while others only need two. Fully kitted weapons come with all their attachments but they cannot be removed, except for the optic.

Barrels, Mags, and Stocks

The following attachments come in different levels, each a different rarity. Level 4 attachments have the same stats as Level 3, but come with additional perks.

Tips

• It is better to equip a Standard Stock on heavier weapons first (LMGs, then ARs, then SMGs) to minimize switch time as the heavier the weapon, the slower their equip and holster speed usually are.

Optics

Icon

Optic attachments, or sights, are attachments that give zoom and more precision to guns. They offer magnification while aiming down sights. The Kraber .50-Cal Sniper has its own 6x-10x Variable optic and cannot accept any others.

Optic	Range	Compatible weapons
1x HCOG "Classic"	Close range	All
1x Holo	Close range	All
2x HCOG "Bruiser"	Close range	All
1x-2x Variable Holo	Close range	All
6x Sniper	Sniper	Snipers
3x HCOG "Ranger"	Mid-range	ARs, LMGs, marksman, snipers
2x-4x Variable AOG	Mid-range	ARs, LMGs, marksman (except the Bocek), snipers
4x-8x Variable Sniper	Sniper	Snipers
1x Digital Threat	Close range	Pistols, shotguns, SMGs
4x-10x Digital Sniper Threat	Sniper	Snipers

Legendary optics highlight enemies, even through smoke. Since this is especially potent long range, the 4x-10x Digital Sniper Threat can only be found in Care Packages or on fully kitted weapons.
