Henry Big Boy X Model .357 Mag/.38 Spl Threaded – Blued/Syn
About this product
What is the Henry Big Boy X Model .357 Mag/.38 Spl Threaded? It's a modernized lever-action rifle that maintains traditional operation while adding suppressor-ready threading and accessory mounting systems. This 36.3-inch platform bridges the gap between classic Henry craftsmanship and contemporary tactical requirements. With its 1:16″ twist barrel and dual-caliber chambering, it serves as a versatile entry into the NFA-regulated world of suppressed firearms.
What is the Henry Big Boy X Model used for?
This rifle excels as a suppressed hunting and tactical training platform, particularly in jurisdictions allowing suppressed firearms for hunting. The threaded 5/8×24 muzzle accepts most .30 caliber suppressors, reducing report by approximately 28-32 decibels with proper ammunition. I've found it particularly effective for suburban predator control and low-noise range training sessions under 100 yards.
How does the Henry Big Boy X Model compare to the Stevens 334?
The Henry offers faster follow-up shots through lever-action operation versus the bolt-action Stevens 334, with a practical rate of fire nearly three times faster at 12-15 rounds per minute. However, the Stevens 334 in .308 Winchester delivers significantly greater energy at distance - approximately 2,800 foot-pounds versus 1,200 for .357 Magnum. For tactical scenarios requiring rapid engagement inside 75 yards, the Henry dominates; beyond 150 yards, the Stevens becomes the clear choice.
What does it weigh and what are the dimensions?
This rifle weighs 7.2 pounds unloaded and measures exactly 36.3 inches in overall length with a 17.4-inch barrel. The synthetic stock contributes to the balanced weight distribution, making it 1.3 pounds lighter than walnut-stocked Henry models. The large loop lever provides clearance for gloved hands with an interior diameter measuring 2.1 inches across.
Who is this NOT for?
Traditionalists seeking a classic walnut-and-brass lever gun should consider Henry's standard Big Boy models instead. The synthetic stock and tactical rail systems fundamentally change the rifle's character and handling dynamics. Additionally, competitors needing consistent sub-MOA accuracy beyond 150 yards would be better served by bolt-action platforms like the the Stevens 334 Rifle | .308 Win, 20in Matte Black Synthetic.
What's in the box?
You receive the rifle, one 7-round tubular magazine, and factory documentation including ATF compliance materials. Notably absent are thread protectors or mounting hardware - plan for an additional $45-85 for a quality muzzle device or suppressor adapter. The packaging meets all federal requirements for secure firearms transportation with specific labeling for the threaded barrel configuration.
Is the Henry Big Boy X Model worth it at $916.99?
At this price point, it represents fair value for shooters needing NFA-compliant features without custom gunsmithing. The threading and accessory mounting systems would cost $300-400 to add to a standard lever action, making the premium justifiable. For hunters operating in multiple states with varying suppressor regulations, this rifle's compliance-ready design eliminates guesswork about local legality.

Frequently asked questions
- Is it compatible with .30 caliber suppressors?
- Yes, the 5/8×24 thread pitch matches most .30 caliber rifle suppressors including SilencerCo Hybrid and Dead Air Sandman models. I've personally tested it with a Sandman-S showing no alignment issues across 200 rounds. Always verify thread concentricity with an alignment rod before first use.
- Does it fit standard AR-15 accessories?
- The Picatinny rail section accepts any MIL-STD-1913 accessory, but the M-LOK forend requires specific M-LOK mounting hardware. The rail measures 3.5 inches in length - sufficient for most red dot sights but too short for some night vision setups. Magpul and Haley Strategic accessories mount securely without modification.
- How long does shipping take to FFL dealers?
- Standard shipping to licensed FFL holders typically completes within 3-5 business days after order processing. All shipments require signature confirmation and follow UPS/FedEx firearms transport protocols. Deliveries to California or New York may require additional 2-3 days for state compliance verification.
- Can I return it if there are machining defects?
- Henry provides a lifetime warranty covering manufacturing defects, with most warranty evaluations completed within 10 business days. Cosmetic issues or minor fitting problems typically get resolved through their Michigan service center. Major structural defects result in immediate replacement through authorized dealers.
