Henry Big Boy 45 Colt Lever Action Octagon Rifle

Powerful Tradition — Octagon Barrel Style Meets Big-Bore Heritage

The Henry Big Boy .45 Colt Lever-Action Octagon Barrel Rifle blends the hard-hitting performance of the .45 Colt cartridge with the timeless aesthetic of an octagonal barrel. Built on Henry’s trusted Big Boy platform, this rifle delivers reliable big-bore ballistics, smooth lever cycling, and heirloom-quality finishes that collectors and hunters both admire.

Octagon Barrel — Balance, Rigidity, and Classic Looks

The standout feature is the 20-inch octagonal blued steel barrel, which adds rigidity for consistent harmonics and a vintage silhouette reminiscent of 19th-century frontier rifles. The octagon profile provides a refined balance and a longer sight radius for improved open-sight accuracy while delivering unmistakable Old West styling.

.45 Colt Performance and Versatility

Chambered for .45 Colt, this Big Boy model offers excellent stopping power for hunting and practical field use. The rifle handles standard .45 Colt loads reliably and provides a satisfying balance of energy and controllable recoil. It’s an ideal choice for hunters, ranchers, and shooters who want classic big-bore capability in a lever-action format.

Solid Brass Receiver and Heirloom Fit & Finish

The solid brass receiver is polished to a mirror finish and paired with brass accents for warm, timeless appeal. Matched with a hand-finished American walnut stock, the result is a rifle that’s as comfortable to carry as it is striking on the wall. The brass and walnut combination matures gracefully over time, evolving into a true family heirloom.

Smooth Lever Action and Practical Features

Henry’s smooth lever mechanism provides reliable feeding and effortless cycling for consistent follow-up shots. The tubular magazine offers practical capacity for field use, and the rifle’s sights (adjustable semi-buckhorn rear / brass bead front) deliver quick target acquisition. The receiver is often drilled & tapped on select SKUs to accept optics if desired.

Made in the USA — Built to Last Generations

As with all Henry rifles, the Big Boy .45 Colt Octagon Barrel is 100% made in the United States, combining traditional workmanship with modern quality control to produce a rifle that shoots beautifully and endures for generations.
