This week, completing five challenges will award the JAK Glassless Optic, an aftermarket part that’s similar to a fan-favorite optic from Advanced Warfare. This guide will explain how to unlock this week’s unique reward, what it does, and provide tips on how to complete every new challenge as quickly as possible.
Week 4 Challenge Reward
Completing five of this week’s challenges will award theJAK Glassless Optic.It has the same visual profile as the red dot sight from Advanced Warfare, although the optic has a blue dot in MW3. Compared to other optics, the Glassless Optictrades ADS speed for Firing Aim Stability.Equipping this optic will reduce your ADS speed by 2%, but your Firing Aim Stability will increase by one point,similar to most MW3 muzzle attachments.
Most weapons that accept red dot optics can equip the Glassless Optic, including ARs, SMGs, LMGs, marksman rifles, and sniper rifles. It cannot be equipped on shotguns, handguns, or weapons that don’t accept optic attachments.
