JS9 attachment compatibility and practice setup
Inspect sourced JS9 attachment fitment, understand missing records, and build a controlled practice setup.
Start with the JS9 reference
The reference record lists 14 base damage, 900 rounds per minute, and 400 m/s muzzle velocity. These values are a versioned community extraction; event variants and later patches can differ.
What the compatibility snapshot contains
No exact compatibility snapshot is matched to JS9. Do not assume another submachine gun accepts the same equipment. Confirm fitment in the live game before saving a setup.
Run a controlled attachment comparison
Keep your JS9, stance, sight, target distance, and burst length the same. Change one attachment at a time. Compare the grouping rather than a single successful spray, then repeat while leaving and returning to cover.
Turn it into a repeatable drill
- Review the 2026-10-28 source record
- Keep the practice conditions repeatable
- Change one variable and record the result
