Abstract: A firearm support brace has an attachment facility operable to removably connect securely to the mounting portion, an arm extending downwardly and rearwardly from the mounting portion, an extension extending from the arm and having an end away from the arm, and a saddle element connected to the end of the extension, such that the firearm is stabilized by positioning the saddle against the upper arm of a user adjacent to the elbow of the user while the barrel is aligned for sighting by the user. The attachment facility may include a first clamp portion connected to the arm, and a second portion removably connected to the first clamp portion. The attachment facility may define a cylindrical aperture. The attachment facility may be rotatable with respect to the firearm about a rotation axis parallel to a barrel axis defined by the barrel.
