Season 5 has made its debut in Modern Warfare 3 and Warzone, bringing with it a plethora of content drops. From high-action game modes to the arrival of two Battle Pass-exclusive weapons, players have quite a lot to dive into. Following the trend of previous seasons, Week 1 of Season 5 also introduces an additional Aftermarket Part, one which players can earn for free.

The JAK Widemouth Barrel is an Aftermarket Part for the MORS Sniper Rifle that essentially converts the weapon into the Blunderbuss from previous Call Of Duty titles. This provides players with essentially a bolt-action Shotgun variant, one that can provide consistent one-shot eliminations on unarmored Operators at close range. Here is the best loadout for the JAK Widemouth Barrel MORS in Modern Warfare 3 and Warzone.

Unlike its regular counterpart, the MORS paired with the JAK Widemouth Barrel can be built the same for both Core Multiplayer and Warzone. With the JAK Widemouth Barrel essentially converting the MORS into a Shotgun, players should focus on improving attributes such as aim-down-sight and sprint-to-fire speed over recoil control, as the weapon will recenter after firing. The attachments below enhance these attributes, and although they don't necessarily make the MORS a top-tier option in the overall meta, they do provide players with a fast weapon capable of one-shotting Operators without armor.

Secondary Recommendations To Pair With JAK Widemouth Barrel MORS

The MORS, with the JAK Widemouth Barrel equipped, is a powerful weapon in Core Multiplayer capable of one-shotting opponents at medium range. However, its heavy reliance on accuracy, and its fairly slow fire rate, can make it difficult to use in hectic gunfights. With this being the case, players can consider running a quick-swap-to Secondary to keep them covered in situations where they either miss a shot or need a quick backup option. Some great options for Multiplayer include the Renetti and the WSP Stinger.

When it comes to Warzone, however, the MORS (with the JAK Widemouth Barrel equipped) is a little less versatile thanks to the game's larger map size — along with the fact that it is less effective at downing a player with full armor in a single shot. However, the weapon is effective at breaking an opponent's armor plates, making it a great weapon for opening close-range gunfights. Therefore, players should opt for a weapon that is capable of performing well in a variety of situations. Such weapons include the BP50, the BAL-27, the RAM-7, and the STG44.
