What is the JAK Widemouth Barrel in MW3 and Warzone?
The JAK Widemouth Barrel is an Aftermarket Part for the MORS sniper rifle. It transforms the rifle into a blunderbuss similar to other weapons that have featured in Advanced Warfare and WWII.
The Aftermarket Part provides players with better mobility, accuracy, and handling at the cost of a huge range reduction and damage output. It excels in close-quarters combat but at longer distances, the standard MORS is a much better pick.
