Design and functional highlights

The 16.5″ finned barrel is more than cosmetic — the fins increase surface area to shed heat faster under extended strings of fire, which helps preserve point of impact during range sessions. The pinned compensator gives the Deluxe model the appearance and legal benefits of an 18″ barrel while maintaining the handling of a shorter carbine. Solid-steel frame and receiver machining delivers rigidity for consistent cycling and long-term durability, and the blued finish resists corrosion while matching the period look.

Ergonomics and handling

Genuine American walnut woodwork balances the piece and offers a tactile, traditional feel. The detachable buttstock pistol grip and vertical foregrip let operators configure the platform for rapid handling or stabilized two-handed shooting. The blade front sight and open adjustable rear sight are straightforward, robust, and easy to use in daylight conditions.

For shooters who value caliber performance, the .45-caliber chambering provides significant terminal energy at typical pistol-carbine ranges and is well-suited to controlled, defensive-style loads as well as classic ammunition choices.
