Key Features
- 16.5″ Octagon Barrel – The shorter barrel keeps this carbine handy in tight spots like brush or a truck cab, without sacrificing accuracy. The octagon profile adds rigidity and that classic Henry look.
- Polished Brass Receiver – This isn’t just for show. The brass receiver is corrosion-resistant and gives the rifle a smooth, premium feel that stands up to years of use. Why it matters: you get a heirloom-quality gun that actually works hard.
- Large Loop Lever – Makes cycling the action easier with gloved hands, especially in cold weather or when you’re in a hurry. Why it matters: you won’t fumble or lose grip when speed counts.
- Adjustable Semi-Buckhorn Rear Sight with Diamond Insert – The reversible insert lets you switch between a standard notch and a fine target notch, depending on your shooting needs. Why it matters: you can dial in your sight picture for plinking or precision without swapping parts.
- Drilled and Tapped Receiver for Scope Mounting – If your eyes aren’t what they used to be, or you want a red dot for fast target acquisition, this carbine is ready out of the box. Why it matters: you don’t need a gunsmith to modernize it.
Who It’s For
This carbine is for the shooter who wants a lightweight, multi-caliber lever gun that’s as fun at the range as it is in the field. It’s a great choice for new gun owners who want a simple, reliable action with mild recoil, and for families who want a gun that everyone from teens to grandpa can shoot comfortably. Hunters will appreciate the compact size for carrying through timber, and collectors will love the brass receiver and walnut stock. If you’re looking for a single gun that does double duty as a plinker and a small-game getter, this is it.
Pros and Cons
- Pros: Four-caliber versatility (shoot .327, .32 H&R, .32 S&W Long, .32 S&W), lightweight at 6.2 lbs, compact 16.5″ barrel, large loop lever for gloved hands, classic brass receiver that won’t rust, and drilled/tapped for optics.
- Cons: The polished brass receiver shows fingerprints and tarnish over time – you’ll want to wipe it down after handling. Also, .327 Federal Magnum ammo can be harder to find than .357 Mag or .44 Mag in some areas, so stock up when you see it.

FAQ
What calibers can the Henry Big Boy Carbine H006MR327 shoot?
Per Henry Repeating Arms specs, this carbine is chambered for .327 Federal Magnum, but it also safely cycles .32 H&R Magnum, .32 S&W Long, and .32 S&W. That means you can practice cheap with .32 S&W Long and hunt with .327 Fed Mag.
Is the receiver drilled and tapped for a scope?
Yes, the polished brass receiver is drilled and tapped for scope mounting, so you can add a red dot or low-power scope without any gunsmith work.
What is the barrel length and twist rate?
The barrel is 16.5″ long with a 1:16″ twist rate. That twist stabilizes both .327 Fed Mag and the shorter .32 H&R rounds well.
Can I use this for hunting?
Absolutely. The .327 Federal Magnum delivers enough energy for small to medium game like deer at reasonable ranges (under 100 yards). The compact carbine length makes it easy to carry in thick cover.
How do I care for the brass receiver?
Wipe the brass receiver with a soft, dry cloth after handling to remove fingerprints and oils. For tarnish, use a brass cleaner like Brasso, but avoid getting it on the blued barrel or walnut stock.
