The Ahrens AR 124 was an American single-seat glider developed by the Ahrens Aircraft Corporation. It was left in the prototype stage, with only three examples built.
The first AR 124 prototype made its first flight in 1974 and the definitive third prototype in 1975. Sales were to begin in late 1979, but the project was put on hold to save resources for the corporation's main product, the AR 404 transport. Ahrens's bankruptcy in 1981 spelled the end for both projects.
The AR 124 had an all-aluminium construction. The wings and the tailplane were of constant chord to simplify production. The same feature was used in the AR 404.
