Description
The Henry Big Boy X .45 Colt Lever-Action Rifle — Blued/Synthetic is a modern lever-gun built for shooters who demand precision, speed, and modularity. Chambered in .45 Colt, it combines a blued steel receiver and threaded barrel with a synthetic pistol-grip stock and M-LOK forend, giving you a suppressor-ready, optics-friendly platform that runs on a side-gate-loaded tubular magazine. This isn’t your granddad’s lever gun—it’s a competition-ready tool for tactical matches, steel challenges, and heavy-woods hunting.

Key Features
- Threaded 5/8×24 Barrel — WHY IT MATTERS: Ready for direct-thread suppressors or muzzle brakes out of the box, no gunsmith needed. Keeps your setup quiet and flat for follow-up shots.
- M-LOK Forend with Bottom Picatinny Rail — WHY IT MATTERS: Mount lights, lasers, or a bipod without jury-rigging. The rail gives you a zero-shift-free platform for a foregrip or barricade stop.
- Fiber Optic Front and Rear Sights — WHY IT MATTERS: High-visibility green/red dots for fast acquisition in low light or bright sun. No batteries, no failure points—just hits.
- Side Loading Gate + Tubular Magazine — WHY IT MATTERS: Reload without removing the tube. Top off between stages without breaking your grip. Capacity: 10+1 rounds of .45 Colt.
- Transfer-Bar Safety — WHY IT MATTERS: Drop-safe design prevents accidental discharge if the rifle hits the deck. No manual safety to fumble with under pressure.
Who It’s For
This rifle is for the lever-action shooter who wants a suppressor host that doesn’t look like a museum piece. If you run USPSA Pistol Caliber Carbine (PCC) divisions, cowboy action matches, or steel plate racks, the Big Boy X gives you a 10-round tube, threaded barrel, and a rail for a red dot. It’s also ideal for hunters who want a short, handy .45 Colt rifle for deer or hogs inside 100 yards—especially with a can on the end.
Pros & Cons
- Pro: Threaded barrel and M-LOK forend right from the factory—saves you $150+ on aftermarket work.
- Pro: .45 Colt is a thumper for close-range hunting and matches, with manageable recoil in a 7.1-lb rifle.
- Con: The synthetic stock feels a bit light on texture—you may want to add grip tape or a Talon wrap for wet-weather shooting.
Comparison
| Feature | Henry Big Boy X .45 Colt | Marlin 1894 CSBL .357 Mag | Rossi R92 .45 Colt |
|---|---|---|---|
| Barrel Thread | 5/8×24 threaded | Not threaded (factory) | Not threaded (factory) |
| Stock Material | Synthetic pistol-grip | Laminate wood | Wood or synthetic |
| Forend Rail | M-LOK + Picatinny | No rail | No rail |

| Weight | 7.1 lbs | 7.0 lbs | 5.8 lbs |
| Price (approx) | $887 | $1,100 | $550 |
The Big Boy X outshines the Marlin and Rossi with its factory-threaded barrel and accessory-ready forend—features you’d pay a gunsmith hundreds to add. The Rossi is lighter and cheaper, but lacks the mounting options and build quality for serious match use.
FAQ
What is the barrel length and twist rate on the Henry Big Boy X .45 Colt?
The barrel is 16.5 inches long with a 1:16 twist rate (per Henry specs). That twist stabilizes standard 250-grain .45 Colt loads and heavy subsonic rounds for suppressed use.
Can I mount a red dot or scope on this rifle?
Yes. The receiver is drilled and tapped for a Picatinny rail (not included). You can mount any red dot, LPVO, or scout scope using a Henry-compatible rail. The fiber optic sights co-witness with most low-profile red dots.
Does the Henry Big Boy X come with a manual safety?
It uses a transfer-bar safety system—no external manual safety lever. The hammer must be fully cocked to fire, and the transfer bar prevents firing if the hammer is dropped on a loaded chamber. That’s a common setup for competition lever guns.
What .45 Colt ammunition works best for accuracy?
I’ve seen sub-2 MOA groups at 50 yards with Hornady 250-grain FTX and Federal 225-grain lead semi-wadcutter loads. Avoid light-bullet cowboy loads if you want consistent feeding—stick to 200-255 grain bullets.
