Muzzle

Muzzle attachments can affect a number of weapon characteristics: Compensators reduce horizontal recoil and muzzle brakes reduce vertical recoil; vent brakes increase optimal range; suppressors dampen your weapon's report so enemies pay less attention to you; and a flash hider reduces visible firing effects and improves accuracy.

Attributes[]

The number of attributes a muzzle modification supplies is based on the rarity of the modification. A standard rarity modification will have 1 major attribute, while a specialized rarity modification will have 2. High-end muzzles will have three major attributes.

It appears that large suppressor modifications are guaranteed to have the Reduced Threat minor attribute.
