The barrel top flat is marked "HOPKINS & ALLEN ARMS" and "45 CAL." The rifle uses an underhammer percussion ignition system with the nipple set in a brass-lined recess ahead of the trigger guard. A strap-style steel/iron receiver with visible side screws supports the action, and a single trigger completes the straightforward firing setup.
The 30-inch full-octagon barrel provides a long sighting plane. Sighting equipment includes a dovetailed blade front sight and an open rear sight with a stepped/elevator slider for height adjustment. The long fore-end is retained by screws.
The hardwood stock has a straight-grip profile and is finished with a crescent brass buttplate. A full-length wooden ramrod is carried beneath the barrel. Length of pull is 14.0.
Production is generally attributed to Numrich Arms marketing under the revived Hopkins & Allen name during the 1960s-1970s U.S. black-powder resurgence. A serial marking is present on the barrel at the breech. Capacity is 1 round.
