Part 70

AP Tracer Rounds: Can be equipped on assault rifles, carbines, battle rifles, and semi-auto snipers. They counter the Mechanic's Armored Insert and do increased damage to armored vehicles. However, they reveal your position with bright bullet trails and can reduce max damage, affecting the four-hit kill potential for several assault rifles and carbines.

Muzzle Attachments: These are fitted to the end of the barrel.

Standard Barrel: The default configuration with no attachments.

Muzzle Brake / Compensator: Redirect propellant gases to reduce recoil. The Muzzle Brake reduces horizontal recoil by 50% and vertical by 17.5%, but penalizes spread recovery rate by 50%. The Compensator reduces vertical recoil by 40%, but increases horizontal recoil by 17% and spread increase per shot (SIPS) by 30%. The Muzzle Brake is often more useful due to easier manual counteraction of vertical recoil.

Heavy Barrel (HBAR): Increases accuracy and reduces recoil by making the barrel stiffer. It provides a 50% reduction to stationary ADS spread and a 20% reduction to stationary ADS spread maximum. It also offers a 20% reduction to ADS/hipfire vertical and horizontal recoil. The downside is a 50% penalty to ADS/hipfire spread when moving, making it best for players who stop before shooting.

Flash Hider: Conceals muzzle flash, which can reveal your position, especially in dark environments. It has no statistical bonuses or penalties and is a good default if no other barrel attachment is used.

Suppressor: Reduces weapon sound and functions as a flash hider. It prevents the player from being marked on the enemy minimap when firing, offering a tactical advantage. Disadvantages include reduced muzzle velocity (making it harder to hit moving targets and increasing bullet drop), exclusion of other muzzle attachments, and increased weapon length. Revolvers cannot use suppressors.
