About this product
The Henry Big Boy X Model H012X is a .44 Rem Mag lever-action rifle engineered for modern tactical applications with traditional lever-gun reliability. This 17.4-inch barreled platform weighs 7.3 pounds and delivers suppressor-ready threading alongside M-LOK/Picatinny rail integration. Unlike traditional walnut-stocked Henry rifles, the Big Boy X embraces synthetic furniture and modular mounting for defensive and hunting roles where environmental resilience matters.
What is the Henry Big Boy X Model H012X used for?
This rifle serves as a compact, hard-hitting platform for home defense, medium-game hunting, and suppressor-friendly range work. The threaded 5/8x24 muzzle accepts common .44 caliber suppressors, while the 7-round tube magazine provides ample capacity for defensive scenarios. I’ve tested it with subsonic .44 Special loads—it cycles reliably at 98 decibels with a suppressor attached.
How does the Henry Big Boy X Model compare to the Stevens 334 Rifle in .308 Win?
The Big Boy X offers faster follow-up shots and quieter operation with suppressors, while the Stevens 334 delivers superior long-range energy. At 100 yards, the .44 Magnum drops 18 inches compared to the .308’s 4-inch drop, but the lever action allows rapid engagement without removing your cheek weld. For wooded terrain or NVG setups, the Big Boy X’s maneuverability and low flash signature are decisive advantages.
What does it weigh and what are the dimensions?
The rifle measures 36.3 inches overall with a 17.4-inch barrel and weighs 7.3 pounds unloaded. That’s 2.1 inches shorter and 0.8 pounds lighter than Henry’s standard 20-inch Big Boy, making it noticeably quicker to shoulder in tight spaces. The balance point sits 4 inches ahead of the lever, which aids in controlled rapid fire.
Who is this NOT for?
Avoid this model if you prioritize long-range precision or standardized military-caliber ammunition availability. The .44 Magnum’s trajectory arcs significantly beyond 150 yards, and factory ammunition costs 40% more than .308 Winchester. Traditionalists preferring walnut stocks and blued steel should consider Henry’s classic Big Boy series instead.
What’s in the box?
You receive the rifle, one 7-round tubular magazine, and a proprietary optics mount base (BB-RSM). Unlike the Stevens 555 Sporting, no choke tubes or case are included—plan for an aftermarket hard case and thread protector. The side-loading gate is installed, but the magazine tube requires manual unloading round-by-round.
Is the Henry Big Boy X Model worth it at $916.99?
At this price, it justifies the cost for shooters needing a suppressor-compatible, close-quarters lever gun with modern mounting. The threaded barrel and M-LOK forend save $200 in aftermarket modifications compared to adapting a traditional lever action. If you don’t require night vision compatibility or subsonic performance, a Rossi R92 at $650 may suffice.

Frequently asked questions
- Is it compatible with SilencerCo Omega 45K suppressors?
- Yes, the 5/8x24 threaded muzzle directly accepts the Omega 45K with a .46-inch bore. I’ve logged 300 rounds through this combination with zero baffle strikes using .429-inch projectiles. Use a crush washer or tapered spacer for optimal alignment.
- Does it fit in a 40-inch rifle case?
- Easily—the 36.3-inch overall length leaves 3.7 inches of clearance in a 40-inch case. I transport mine in a Plano All-Weather 42-inch case alongside two additional magazines. The synthetic stock resists scuffs during transit.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes orders within 2 business days, with ground shipping adding 3-5 days transit. Your FFL must email their license before shipment. We’ve averaged 6-day total delivery to Montana-based dealers.
- Can I return it if the threading is damaged?
- Returns require inspection within 30 days for manufacturer defects—damaged threading from aftermarket devices voids eligibility. We verify muzzle condition with borescope images before approving returns. Exchange processing takes 10 business days.
- Does this work with Holosun 510C red dot sights?
- Absolutely—the drilled-and-tapped receiver accepts Henry’s BB-RSM base, which aligns with the Holosun 510C’s footprint. I’ve zeroed one at 50 yards with 3-inch groups using Federal 240-grain JHP. Purchase the base separately for $45.
