Abstract: A graphical configuration editor for highway-rail grade crossings includes a storage device comprising an application, and a processor configured to execute instructions of the application to generate, on a display, identifications of a plurality of objects for controlling a grade crossing, receive user input comprising a selection of objects out of the plurality of objects, generate, on the display, a visual representation of a track plan using the selected objects, and store the track plan in the storage device. Further, associated method(s) and a grade crossing controller are described.

Abstract: A muzzle brake for a firearm provided herein generally includes a housing having a chamber and an insert removably couplable to the housing such that the insert is interchangeable depending on the caliber of projectile. The insert includes a body with a central bore defining a projectile axis, the central bore at least partially extending toward an end of the housing within the chamber. The muzzle brake may further include a first lateral port extending from the chamber through the housing and be configured to expel combustion gases away from the housing and a first baffle projecting radially from the body and disposed at a location along the body configured to direct a portion of the combustion gases toward the first lateral port. The muzzle brake may further include an upward port configured to expel combustion gases in direction to counteract muzzle lift of the firearm.
