Once you have unlocked an Barrel attachment for your gun, access the Gunsmith menu, go into the Loadout menu, select a custom loadout, highlight the weapon, and press the button corresponding to the Gunsmith menu.
Note that you will need to have Custom Loadouts unlocked at Progression Level 4 to access the Gunsmith.
Barrels mostly modify the effective range and recoil control of your weapon. Longer Barrels increase bullet velocity and damage at longer distances, while Shorter Barrels focus on weapon handling such as jumping ADS and Jump-to-Fire speeds.
Some barrels, such as the Damage Barrel, can modify the damage dealt to body part such as the head at the cost of several drawbacks such as lesser recoil control.
