Damage, time to kill and the in-game Gunsmith bars are not published by Activision, so they are not shown. Community-reported movement, handling and recoil values follow in their own section.

These are arithmetic on the published fire rate and magazine size. They ignore reloads, recoil and burst or pump cycling, and they say nothing about damage.

How this is sourced

Movement, handling, recoil and ammo values for the .50 GS with nothing attached. Activision has not published them, and they are launch data that changes with patches. Fire rate, magazine size and total rounds are Activision's published numbers. Damage and time to kill are not included.

Each attachment below lists its biggest changes as a percentage of the value above, and the changes of everything equipped are multiplied together (the source's rule, not confirmed by Activision). The Apex Attachment is listed with its own changes further down. Where these numbers come from.

How this is sourced

Activision has not published the names or effects of the individual attachments, so there is no official list to check these against. They are grouped by type in Gunsmith order. Where CODMunity lists a stat change for an attachment on this weapon, the biggest changes are printed under it as a percentage of the base value; "No stat change reported" means the source lists none, not that there is none. Where the names come from.
