The TRAP-M1 is very good since the arsenal update, but it has a bug that makes it very unfun to use. When pressing the "Sprint/Hold Breath" hotkey while aiming down sights (any sights) the character doesn't unscope to sprint. Instead, nothing happens as though the game tries to hold breath. It makes repositioning after a kill extremely tedious. This is an issue because the TRAP-M1 doesn't have weapon sway with any scope. The expected behavior for every scope without sway is to sprint when pressing the "Sprint/Hold Breath" key while aiming down sights. The TRAP-M1 is the only exception that I know of where that hotkey does nothing.
