How to complete the build

Start with the SIG MPX from Peacekeeper LL2 and install the required grip, flash hider and flashlight.

The Steiner LAS/TAC 2 is available from Ref LL2 or Mechanic LL3. Check your access to that specific flashlight before spending money on the rest of the build.

Check the complete weapon in the inspection window before handing it over. The quest checkmark can be inconsistent even when a build qualifies, so a missing marker alone does not prove the weapon cannot be submitted.
