JAK Widemouth Barrel explained

The JAK Widemouth Barrel AMP turns the MORS Sniper Rifle into the Blunderbuss Shotgun, previously seen in SHG’s Advanced Warfare and WWII. This attachment grants better overall mobility, accuracy, and handling, while considerably reducing the range, damage, and recoil control values.

The Blunderbuss wasn’t anywhere near the meta in previous titles and it still struggles to stand out in MW3 and Warzone. This is mainly due to the hefty cons it brings, especially with the Barrel and Ammunition attachments being restricted.

Still, it offers fun and challenging gameplay thanks to its unique reload and performance, especially at close ranges. While the original version featured a distinctive muzzle-loading animation, the MW3 version uses the MORS’ reload system.
