The RUST Muzzle Brake is a weapon attachment that allows players to modify their guns’ overall recoil. Simply put, the muzzle brake will drastically reduce the amount of recoil present when shooting but simultaneously reduce the damage output and bullet velocity by a rather large margin (20%).
The alteration is most viewed with guns that naturally shoot without a distinct recoil pattern, such as the SAR or M249. Many prefer using the Silencer over the muzzle brake due to the similar effect without such harsh consequences.
RUST players may acquire a muzzle brake through a number of mid-to-high tier crates, locked crates, or as drops from scientists. Players may also learn them directly via researching or investing considerable Scrap into the Tier 2 Workbench tech tree.
