The Big Bore designation identifies this as the .58 caliber variant of the CVA Mountain Rifle, offering a larger bore in a traditional single-shot muzzleloading platform. It uses a percussion sidelock with a drum-and-nipple bolster and an exposed hammer for ignition.
The 32-inch full-length octagonal barrel provides the classic long-rifle profile. A dovetailed brass blade front sight is installed for a period-correct sighting setup.
The half-stock hardwood stock is outfitted with brass furniture, including a crescent buttplate, and a pewter nose cap. A wood ramrod with a metal tip is carried by two pipes on an under-barrel rib and a separate entry pipe inlet into the fore-stock, and there is a small oval brass inlay with a slotted opening near the breech on the left side.
Barrel markings read "Connecticut Valley Arms, Inc." and "Black Powder Only .58 Cal. Spain," confirming its Spanish manufacture. Light decorative engraving appears on the hammer, adding a subtle traditional touch.
This reproduction muzzleloader has a 14.0-inch length of pull and a single-round capacity, staying true to the classic mountain rifle layout and handling.
