Custom Killer

is an achievement in Windforge.

Summary
Complete all Lars side quests.

Tips
If you don't start the main questline and complete all of Lars' missions, the achievement won't pop until you do.

1. Sawed-off Shotgun: Requires Hunting Shotgun (just a shotgun works, otherwise use hunting gun recipe with 10 iron to make a shotgun)

2. Recoil Rifle: Requires Machine Gun (automatic rifle recipe with steel, or buy one from vendor at random)

3. Scoped Rifle: Requires Sniper rifle (rifle recipe) plus scope (teaches you scope recipe when he gives you quest, but you will need lens recipe from somewhere or find a scope randomly for sale)
