Henry Big Boy .45 Colt Lever Action Rifle, 20" Barrel, 10-Round Capacity, American Walnut Stock - H012GCL

The Henry Big Boy .45 Colt lever action rifle is a modern reimagining of a classic American platform, built for hunters and shooters who value both heritage and reliability. Chambered in .45 Colt—a round with deep roots in frontier history and modern hunting versatility—this rifle combines the proven lever-action mechanism with practical features that work at the range, in the field, or on the trail. The 20-inch barrel balances portability with velocity, while the 10-round capacity gives you enough ammunition on hand for most hunting scenarios without excessive weight.

What sets the Big Boy apart is thoughtful execution in the details. The American walnut furniture feels substantial and warm in your hands, while the large loop lever accommodates gloved operation in cold weather or quick cycling in the field. Sights come sorted: a fully adjustable semi-buckhorn rear with a diamond insert for precision, paired with a brass bead front for rapid target acquisition. If you prefer optics, the rifle ships drilled and tapped for scope rings, and includes Henry's BB-RSM scope mount base. The blued steel receiver and round barrel develop character over time and weather better than polished finishes.

A transfer bar safety ensures the gun won't fire if dropped, while the side gate loading system—a modern convenience—lets you top off rounds without cycling the action. The solid rubber recoil pad absorbs what little recoil .45 Colt produces, and swivel studs make mounting a sling straightforward. At 7 pounds and 37.5 inches overall, the Big Boy won't fatigue you on a full day afield yet has enough weight to settle your shooting rhythm.

This is a rifle for shooters who appreciate that sometimes the best tool isn't the newest one—it's the one that was proven right the first time, refined by a manufacturer that knows lever guns inside and out.

Frequently Asked Questions

Is the Henry Big Boy .45 Colt drilled and tapped for a scope?

Yes. The receiver is drilled and tapped for scope rings, and the rifle ships with Henry's BB-RSM scope mount base. You can run irons as-is or upgrade to a low-power optic without gunsmithing.

What's the length of pull, and will it fit me?

Length of pull is 14 inches, measured from the trigger to the center of the recoil pad. This is a standard rifle dimension and typically accommodates shooters from youth to average adult frame—if you're outside that range, try before you buy or measure a rifle you shoot comfortably.

Can I use the Henry Big Boy for hunting large game?

.45 Colt is suitable for deer, hogs, and similar game at hunting ranges. The 10-round capacity and lever action make follow-up shots quick if needed. Check your local regulations to confirm .45 Colt is legal for the game and season you're pursuing.

Does it come with scope rings or just the mount base?

The rifle includes the BB-RSM scope mount base. Scope rings are sold separately—you'll need to source rings that match your base.
