What's Included
- Mowery Ethan Allen .50 BPM percussion single-shot muzzleloader rifle
This rifle is a Mowrey Gun Works reproduction of the Ethan Allen & Thurber side-hammer pattern, executed with a brass boxlock-style frame that incorporates the trigger guard. The hammer is positioned on the left side, true to the historical style, and the build is noted as made in the USA.
The 28-inch octagon steel barrel is configured for .50 BPM black powder and uses a percussion cap ignition in a single-shot muzzleloading format. Capacity is one round, aligning with traditional muzzleloader operation.
Stocking is in curly (tiger) maple with a long fore-end, complemented by brass furniture that includes a crescent buttplate and ramrod thimbles. The length of pull measures 14.0 inches, and the brass frame/receiver presents a uniform brass finish.
Sighting is handled by open iron sights: a dovetailed front blade and an adjustable open rear sight with a sliding elevator insert. Markings include a serial marking on the top barrel flat and a maker's stamp on the barrel top flat that is partially legible.
