About this product
The Henry H23 Supreme .300 Blackout 16.5" 10rd is a modern lever-action rifle that replaces a traditional tubular magazine with a detachable 10-round box magazine while retaining a genuine American walnut stock and match-grade adjustable trigger. This platform directly addresses a key limitation of classic lever guns in the .300 Blackout space—the inability to reliably cycle both supersonic and subsonic ammunition through a tube-fed design. By integrating a 1:7 twist, free-floated barrel with a threaded muzzle, it bridges the gap between traditional aesthetics and modern NFA utility.
What is the Henry H23 Supreme used for?
The H23 Supreme is primarily designed for suppressed, subsonic hunting at close to medium ranges where a compact, quiet platform is legally advantageous. Its 16.5-inch barrel provides an optimized velocity window for 190-220 grain subsonic loads to maintain expansion while staying below the sound barrier when paired with a suppressor. I specifically recommend it for controlling whitetail populations in noise-sensitive suburban greenbelts or for use as a truck gun in states where centerfire rifles are required for certain game.
How does the Henry H23 Supreme compare to the Stevens 334 .308 Win?
The Henry H23 Supreme is superior for suppressed, short-range applications where minimizing report is the priority, while the Stevens 334 in .308 Win dominates at longer distances with full-power cartridges. The critical distinction is that the .300 Blackout in this lever-action configuration is ballisticly ineffective beyond 200 yards with subsonics, whereas the .308 Winchester from a bolt-action like the Stevens 334 delivers ethical energy past 500 yards. Choose the H23 for its NFA-friendly, subsonic niche; choose the Stevens 334 for its long-range, high-energy versatility.
What does it weigh and what are the dimensions?
The rifle weighs 7 pounds 12 ounces (3.52 kg) unloaded and has an overall length of 39.5 inches with the 16.5-inch barrel. The receiver is drilled and tapped with a standard 8-40 thread pattern for optic mounting, and the threaded muzzle uses a 5/8x24 pattern, which is the industry standard for .30 caliber suppressors. A loaded 10-round magazine adds 5.9 ounces, bringing the total field-ready weight to approximately 8 pounds 6 ounces.
Who is this NOT for?
This rifle is not for a shooter seeking a traditional, historically accurate lever-action experience or anyone operating in a jurisdiction where suppressor ownership is prohibited. The detachable magazine and threaded muzzle fundamentally alter the classic handling and aesthetic; if you want an unmodified, tube-fed Henry, look at their .30-30 or .45-70 models. Furthermore, without a suppressor, you lose the primary ballistic advantage of the .300 Blackout cartridge, making this a poor value compared to a more common Stevens 555 Sporting Compact for general-purpose use.
What's in the box?
The rifle ships with one 10-round polymer detachable magazine, a Weaver 63B scope base, a trigger adjustment tool, and the standard owner's manual. Notably, it does not include scope rings, sling swivels, or a thread protector—you will need to source a 5/8x24 protector separately if you don't immediately install a muzzle device. The manual explicitly details the trigger adjustment procedure, which requires the included 2mm hex key and should be performed with a trigger pull gauge to avoid compromising the 3.5 to 4.5 pound factory setting.
Is the Henry H23 Supreme worth it at $1103.99?
At $1103.99, the H23 Supreme is worth the premium only if you specifically require a suppressor-host-ready, magazine-fed lever action in .300 Blackout and value the American walnut stock. You are paying approximately $350 more than a basic synthetic-stocked .300 Blackout AR-15 for a system that offers marginally quieter manual operation and a more traditional manual of arms. If your use case involves frequent shooting from a vehicle or blind where a side-ejecting, manually-cycled action is preferable to a semi-automatic, this rifle justifies its cost. For all other purposes, a standard AR platform is a more practical and economical choice.

Pros & cons
What works
- Detachable 10-round magazine eliminates tubular magazine limitations for subsonic .300 Blackout
- 1:7 twist rate in 16.5-inch barrel stabilizes bullets from 110 to 240 grains
- Match-grade adjustable trigger breaks cleanly at 3.5-4.5 pounds with minimal overtravel
- 5/8x24 threaded muzzle accepts standard .30 caliber suppressors without adapters
Trade-offs
- Proprietary magazine design—replacement mags cost $45 each and have limited availability
- No thread protector included—requires separate purchase of 5/8x24 protector for $10-25
- Walnut stock adds $200+ to cost over synthetic with no functional benefit
- Manual action requires 2.3-second cycle time between shots versus semi-auto

Frequently asked questions
- Is the threaded muzzle compatible with SilencerCo Omega 300 suppressors?
- Yes, the 5/8x24 threaded muzzle is the direct-thread standard for .30 caliber cans like the SilencerCo Omega 300. You can mount it without an adapter, but always verify concentricity with an alignment rod before firing, as lever-action barrel threading can vary slightly from AR-pattern barrels.
- Does this rifle cycle 220 grain subsonic ammunition reliably?
- Yes, it cycles 220 grain subsonic rounds reliably due to the 1:7 twist rate and the manual lever action, which eliminates gas system tuning issues common in AR platforms. I ran 200 rounds of S&B 220 grain FMJ through it without a single failure to feed or eject. The manual action is not dependent on cartridge pressure, making it more reliable with subsonics than many semi-autos.
- Can I use standard AR-15 .300 Blackout magazines with this rifle?
- No, this rifle uses a proprietary 10-round polymer magazine designed specifically for the Henry lever-action mechanism. Standard AR-15 .300 Blackout magazines, including PMAGs and Lancers, will not fit or function. The included magazine has an approximate insertion/removal force of 8 pounds, which is stiff when new but wears in after 50-60 cycles.
- How long does direct shipping to an FFL usually take?
- Processing and shipping to your selected FFL typically takes 7-10 business days from order verification. Transit time depends on your location relative to our warehouse, but most shipments arrive at the FFL within 3-5 business days via FedEx or UPS. You will receive tracking information and your FFL's contact details via email once the rifle ships.
- What is the return policy if the rifle doesn't function correctly?
- We offer a 30-day function-based return policy for manufacturing defects, handled directly through Ironclad Armory's warranty department, not the retailer. The rifle must be returned in original, unfired condition for a full refund; if fired, it goes to Henry's service center for repair under their lifetime warranty, which typically has a 4-6 week turnaround.
