SD Instant Grat | Call of Duty Wiki

"Added components allow for bypassing the initial charge sequence."

— Gunsmith description

The SD Instant Grat is a Barrel attachment available uniquely for the EX1 Assault Rifle in Call of Duty: Vanguard. It helps to increase the recoil control, accuracy and flinch resistance as well as the removal of the charge-up time and reduced scope sway and gun bob. However, this in cause lowers the aim down sight, movement and sprint to fire speed respectfully.
