Henry H1 Sporter .22 WMR 18.5in Threaded Barrel
About this product
The Henry H1 Sporter .22 WMR 18.5in Threaded Barrel is a modern lever-action rimfire rifle designed to bridge classic aesthetics with contemporary accessory mounting, specifically for shooters who need to attach a suppressor or optic under a straightforward regulatory framework. It achieves this with an integrated Picatinny rail and a standard 1/2-28 threaded barrel, housed in a platform that weighs 5.35 lbs and measures 36.5 inches overall. This particular configuration from Ironclad Armory directly addresses the legal gray area many shooters encounter when trying to modify traditional lever-actions for suppressor use.
What is the Henry H1 Sporter .22 WMR used for?
The H1 Sporter is used for suppressed small-game hunting and range training where low noise and optic-ready precision are required. Its .22 Winchester Magnum Rimfire chambering offers better terminal performance on varmints compared to standard .22LR, and the threaded barrel allows for direct attachment of a suppressor without modifying a non-threaded barrel—a process that often requires ATF Form 1 approval if done post-manufacture. I find it most effective for shooting duties like prairie dog control or pest elimination on noise-sensitive properties where its 18.5-inch barrel provides optimal velocity for the .22 WMR cartridge.
How does the Henry H1 Sporter compare to the Stevens 334 Rifle?
The Henry H1 Sporter is better for users who value traditional manual operation and suppressor use, while the Stevens 334 Rifle in .308 Win is better for hunting medium game at longer ranges. The key mechanical difference is action type: the H1 uses a lever-action cycling system with a tubular magazine, while the Stevens 334 uses a centerfire bolt-action with a detachable box magazine. For suppressing, the H1's 18.5-inch barrel with factory threading presents a simpler, legally clearer path compared to threading an unported barrel on most bolt-actions, which can be considered manufacturing a firearm under the NFA.
What does it weigh and what are the dimensions?
This rifle weighs 5.35 lbs and has a 36.5-inch overall length with an 18.5-inch barrel. The weight distribution, aided by the solid American walnut Monte Carlo stock, keeps the center of gravity just forward of the receiver for stable off-hand shooting. The 18.5-inch barrel is the minimum length I recommend for .22 WMR to achieve reliable powder burn and maximize the velocity advantage over .22LR without entering NFA Short-Barreled Rifle (SBR) territory, which begins at barrel lengths under 16 inches.
Who is this NOT for?
This rifle is not for high-volume plinkers seeking the cheapest ammunition or for hunters pursuing game larger than coyote. The .22 WMR ammunition costs approximately 40 to 60 cents per round compared to .22LR at under 10 cents, making sustained range use economically inefficient. Furthermore, the lever-action design, while classic, has a slower practical rate of fire and requires more manual dexterity than a semi-automatic rimfire rifle, something to consider if you're transitioning from a platform like a Ruger 10/22.
What's in the box?
The rifle ships with the firearm, a factory-installed tubular magazine, and a manual—it does not include an optic, rings, or a muzzle device. You will need to source your own 1/2-28 thread protector or suppressor, and an optic with a Picatinny-compatible mounting system. I advise purchasing a set of medium-height scope rings separately, as the integrated rail sits low; typical 40mm objective lens scopes require at least 0.87 inches of ring height to clear the barrel.
Is the Henry H1 Sporter worth it at $606.99?
At $606.99, it is worth the price for a shooter who specifically needs a suppressor-ready, optic-ready .22 WMR lever-action to avoid NFA paperwork for barrel modification. You are paying a premium for the factory-threaded barrel and integrated Picatinny rail, features not typically found on traditional lever-actions like older Henry models. For a shooter who doesn't plan to use a suppressor and prefers a shotgun for similar small-game roles, the Stevens 555 Sporting 20 Gauge might be a more versatile, albeit louder, alternative at a similar price point.

Pros & cons
What works
- 18.5-inch barrel with factory 1/2-28 threads — avoids ATF Form 1 for barrel modification
- 5.35 lb total weight — balances well for off-hand shooting versus heavier bolt-actions
- Integrated Picatinny rail — eliminates need for aftermarket drill-and-tap receiver work
- 10-round tubular magazine capacity — adequate for most small-game hunting scenarios
Trade-offs
- Lacks iron sights — requires immediate optic purchase ($150+ minimum) to be functional
- .22 WMR ammunition costs ~60 cents/round — 6x more expensive than .22LR for practice
- Monte Carlo stock comb is fixed — not adjustable for different optic/cheek weld heights

Frequently asked questions
- Will standard .22LR ammunition work in this rifle?
- No, it will not. This rifle is chambered exclusively for .22 Winchester Magnum Rimfire (.22 WMR), which is dimensionally different and operates at a higher pressure than .22 Long Rifle. Attempting to chamber and fire .22LR in this rifle can cause a dangerous bore obstruction. Always verify the cartridge marking on the base of the case reads '.22 WMR' or '.22 Magnum'.
- What thread pattern is the barrel for a suppressor?
- The barrel uses a standard 1/2-28 UNEF thread pattern, which is the most common thread for rimfire and many centerfire .22 caliber silencers. This means it is directly compatible with suppressors from brands like SilencerCo, Dead Air, and Rugged that offer 1/2-28 direct-thread mounts. Always ensure your local and state laws permit suppressor ownership and use on threaded rifles.
- What is the magazine capacity?
- The rifle uses a tubular magazine located under the barrel. Based on the .22 WMR cartridge length and the 18.5-inch barrel profile, the capacity is 10 rounds. Loading is performed through a port in the tube magazine located under the muzzle end cap. Always refer to your local regulations, as some jurisdictions may have magazine capacity restrictions for rimfire rifles.
- Does the Picatinny rail allow for co-witnessing iron sights?
- No, it does not. The integrated Picatinny rail on the receiver is the sole sight mounting interface; the rifle does not come with iron sights installed or provisioned. Once you mount an optic on the rail, it occupies the entire sight plane. If you desire iron sights as a backup, you would need to source a Picatinny rail section with a rear aperture or a specialized scope mount with integrated ghost-ring sights.
- How long does shipping to an FFL take?
- Processing and shipping to your selected Federal Firearms License (FFL) holder typically takes 3 to 5 business days after order verification from Ironclad Armory. The total delivery time depends on your location and the shipping carrier (usually UPS or FedEx). You must have your chosen FFL dealer's license information ready at checkout to prevent delays. The rifle will not ship directly to your home address.
