Modern Warfare 3: How to unlock the KR Intlas LSJ-3 attachment

The KR Intlas LSJ-3 is one of the many aftermarket parts you can collect in Modern Warfare 3. These are weapon modifiers that will transform the weapon it is applied to. In this case, it will add a scope to any weapon that it is applied to, making it a special aftermarket part since it isn’t exclusive to a single specific weapon. While it may bring magnification, aiming stability, and ADS speed, you will also be more visible due to the resulting laser and sniper glint. Be sure to weigh out the following pros and cons so that you can choose whether to equip it or not.

ProsCons
4.0x Magnification
Aiming Stability
Aim Down Sight Speed
Laser Visible to Enemies
Very Small Sniper Glint
Laser Visible in ADS

So, how do you unlock the KR Intlas LSJ-3 attachment? Just like several other attachments, weapons, or aftermarket parts, this scope is a weekly unlock. This means that you will have to complete a total of 5 weekly challenges from week 4 to get it. This applies to Multiplayer, Zombies, and Battle Royale challenges, so be sure to pick the ones that better suit your preferences. As an example, here are the Week 4 Multiplayer challenges:
