Call of Duty: Modern Warfare 3’ssecond season has released its mid-season content update, featuring new weapons, events, and maps for players to experience. This update also came with a new set of Weekly Challenges that run until the end of this season, giving players some new Aftermarket attachments and cosmetics to earn.

This week, completing any five challenges will unlock the SOA Subverter, a powerful battle rifle that might dethrone the BAS-B as MW3’s best automatic weapon. This guide will explain how to unlock this weapon, give a brief overview of its base stats, and provide tips on how to complete every Week 5 challenge in MW3’s second season.

Modern Warfare 3 SOA Subverter Battle Rifle

Week 5 Challenge Reward

Upon completing five of this week’s challenges, you will unlock theSOA Subverter.This is a full-auto battle rifle thatdirectly competes with MW3’s best automatic weapons. It fires 697 rounds per minute, deals 44 damage to the torso, and has a solid base ADS speed of 278ms. Its only major downside is its mobility stats, suffering from a rather low ADS movement scalar and poor sprint speed.

Builds for this weapon can either lean into the SOA’s superb long-range accuracy or morph it into an AR/SMG hybrid. It does have a fairly small magazine of 20 rounds, however, so a magazine extension is recommended for virtually every Gunsmith build.
