Attachment package
Evidence-backed Beta build. This page records a readable four-attachment M4 setup from the supplied capture. It is not a universal best loadout; the screenshot shows the complete setup's visible stat deltas but does not isolate each attachment's contribution.
| Slot | Attachment |
|---|---|
| 1 | FSS IS300 Heavy Silencer |
| 2 | SZ GEN.6 PEQ Laser |
| 3 | Demo HVR2 Stock |
| 4 | FSS Fireline Grip |
How to read this build
The laser explicitly improves sprint-to-fire and aim-down-sight speed while becoming visible in ADS. Individual claims for the other named attachments are withheld where the capture does not isolate them.
