The Old Army’s all-steel construction reflects Ruger’s investment-cast approach, delivering a sturdy percussion revolver built for repeated use with black powder. The frame, cylinder, and barrel share a matching silver-tone brushed steel finish, complemented by walnut grips with Ruger medallions.
Its 7.5 inch barrel pairs with target-style sights: a fully adjustable square-notch rear and a pinned square-blade front on a ramped base. This sighting setup supports precise elevation and windage adjustments.
The cap-and-ball system features an integral under-barrel loading lever with a spring-loaded rammer for seating projectiles. The unfluted six-shot cylinder is clearly rollmarked "FOR BLACK POWDER ONLY," underscoring proper use with black powder charges.
Control and safety elements include single-action-only operation with an external hammer, cylinder safety notches, and a half-cock notch. Period-correct markings include the top-of-barrel rollmark "STURM, RUGER & CO., INC. SOUTHPORT, CONN. U.S.A."
