Gunsmith Master – Part 1 starts the Master chain with an HK 416A5 in a specific tan and FDE configuration. Matching the component colors is part of the job, and this rifle has an 80-durability requirement rather than the 60 shown on many other Gunsmith builds.
Requirements
- Must be level 27 to start this quest.
- Mechanic loyalty level 4.
Objectives
- Modify an HK 416A5 to comply with the given specifications
Weapon specifications
- 80 Durability
- 50 or more ergonomics
- 310 or less recoil
- 4 kg or less in weight
- 300 or greater sighting range
- A magazine with a capacity of at least 30
- SureFire SOCOM556-RC2 5.56×45 sound suppressor

- EOTech EXPS3-0 holographic sight (Tan)
- AR-15 Magpul UBR GEN2 stock (FDE)
- AR-15 Magpul MOE pistol grip (FDE)
- L3Harris LA-5B/PEQ tactical device
How to complete the build
Use a standard black HK 416A5. Peacekeeper LL3 sells the base rifle after Weapons Circulation, while several of the required components need higher trader access.
Fit the FDE grip, foregrip and stock, tan EOTech sight, RC2 suppressor and LA-5B/PEQ. Empty the chamber before checking the 4 kg weight limit.
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.
Example parts and trader access
These parts form an example configuration. Follow any alternative-part choices in the table and check the assembled weapon against every required stat. LL refers to trader loyalty level.
