Lockout Muzzle Brake

The Lockout Muzzle Brake is a Prestige-tier barrel slot weapon mod in Marathon, exclusively compatible with the BR33 Volley Rifle. It reduces hipfire spread by 1.8 degrees and lowers the weapon's weight by 18 points, improving movement speed while carrying the rifle. These bonuses make the BR33 significantly more viable in close-to-medium range situations where snapping shots from the hip is necessary, while also increasing the runner's mobility in fast-moving firefights.

As a Prestige-tier mod, the Lockout Muzzle Brake represents a rare and powerful attachment that fundamentally changes how the BR33 Volley Rifle handles outside of traditional scoped play. The weight reduction allows runners to reposition quickly between shots, while the tightened hipfire spread means unscoped rounds are far less likely to miss at close range. For players who have committed to the BR33 as their primary rifle, acquiring this mod substantially expands the weapon's utility across the full range of combat distances found in Marathon's extraction scenarios.
