The invention relates to weapon mount systems that can be locked into a particular position. In an embodiment, the invention includes a weapon mount including a base structure; a mounting structure pivotably coupled to the base structure; a weapon cradle pivotably coupled to the mounting structure, the weapon cradle configured to hold a weapon. The weapon mount also includes a first locking mechanism configured to restrict pivoting of the weapon cradle relative to the mounting structure in a vertical plane, the first locking mechanism comprising a first brake caliper; and a first brake rotor, wherein the first brake caliper selectively engages the first brake rotor. The weapon mount also includes a second locking mechanism configured to restrict pivoting of the mounting structure relative to the base structure in a horizontal plane, the second locking mechanism comprising a second brake caliper; and a second brake rotor, wherein the second brake caliper selectively engages the second brake rotor. The weapon mount also includes a first control interface configured to actuate the first locking mechanism and a second control interface configured to actuate the second locking mechanism. Other embodiments are also included herein.
