JAK Slash Underbarrel explained

The JAK Slash is an Underbarrel vertical grip attachment that enhances recoil control, movement speed, sprinting, and Tac Sprinting. It also functions as a combat knife when meleeing with the gun equipped.

This attachment is available to any gun with Underbarrel capabilities, including all weapon categories except Sniper Rifles.

While not a huge modification like other AMPs, the JAK Slash is ideal for players who enjoy close-quarters combat, as it includes an integrated knife if their preferred weapon supports the Underbarrel attachment section. This will allow them to eliminate any nearby threats quickly.

Be sure to use the best controller settings and audio setup to complete all the required challenges and unlock the new Aftermarket Part in the game.
