Thompson Center Hawken .45 Cal Percussion Muzzleloader with Tasco 1860 4×15 Brass Scope

Produced in the United States and now discontinued in this caliber, it combines a 28-inch octagonal 4140 steel barrel and double-set triggers with a factory-style walnut stock.

What’s Included
- Tasco 1860 4×15 brass reproduction Malcolm-type scope with external micrometer mounts (approx. 32" tube)
The 28-inch octagonal barrel is crafted from 4140 steel and secured with Thompson/Center’s hooked breech system, allowing easy removal for cleaning and potential caliber swaps. A 1:48 twist stabilizes both round ball and conical projectiles, giving the shooter flexibility at the range or in the field.
The percussion caplock action pairs with an external hammer and a traditional double-set trigger, providing the crisp let-off favored by target shooters. The rifle’s blued finish contrasts with the richly grained walnut stock, which features a cheek-piece for steady sight alignment.
Iron sights remain in place—dovetail blade front and adjustable semi-buckhorn rear—so the shooter can choose between open sights or the included Tasco 1860 scope. The brass-bodied 4×15 optic mirrors 19th-century Malcolm designs and is itself a sought-after collectible from the 1970s–80s.
At 14.5 inches, the length of pull suits most adult shooters, while the single-shot design retains the authentic handling of the original Hawken pattern. Overall, this rifle delivers a blend of historical style, reliable modern construction, and hard-to-find .45 caliber chambering.
