Henry H1 Mare’s Leg .22 S/L/LR 12.875in 10-Rd Blued/Walnut
About this product
The Henry H1 Mare’s Leg is a legally configured pistol that delivers a classic lever-action repeater experience in a 24.5-inch overall package, avoiding the registration requirements of a Short-Barreled Rifle (SBR) under the National Firearms Act. It uses a .22 caliber rimfire system with a 12.875-inch barrel and a tubular magazine, blending historical firearm ergonomics with modern recreational practicality. For shooters who value traditional mechanics over platform size, this model offers an entry point into lever-gun handling without the paperwork wait and $200 tax stamp associated with Title II firearms.
What is the Henry H1 Mare’s Leg used for?
This firearm is primarily used for recreational target shooting, pest control, and introducing new shooters to lever-action mechanics under direct adult supervision. Its .22 Long Rifle chambering makes it a low-cost, low-recoil training tool, while its compact 4.45 lb weight and 24.5-inch overall length make it suitable for packable carry in controlled backcountry or ranch environments where noise discipline and portability are priorities. It is not designed for defensive engagements or hunting larger game, as the .22 LR cartridge lacks the necessary terminal ballistics for ethical harvests beyond small varmints.
How does the Henry H1 Mare’s Leg compare to a Stevens 334 rifle?
The Mare’s Leg is operationally faster for follow-up shots but less precise beyond 50 yards when compared directly to our Stevens 334 Rifle in .308 Win. The Stevens 334 offers a locked-breech bolt action that consistently holds sub-MOA groups at 100 yards with match ammunition, while the H1’s lever pistol is best for casual plinking where rapid, minute-of-soda-can accuracy is acceptable. The .308 Winchester in the Stevens platform provides 2,800 ft-lbs of muzzle energy, dramatically outperforming the H1’s 140 ft-lbs from a .22 LR, making the Stevens the clear choice for any hunting application where power is a prerequisite.
What does it weigh and what are the dimensions?
The Henry H1 Mare’s Leg weighs 4.45 pounds (1,997 grams) with an empty tubular magazine installed. Its barrel length is 12.875 inches (327 mm), and its overall length from buttplate to muzzle is precisely 24.5 inches (622 mm) — a full 15 inches shorter than a standard Henry .22 rifle configured with a 20-inch barrel. The straight-grip American walnut stock contributes approximately 1.75 lbs to the total weight, and the large-loop lever has an internal diameter of 3.125 inches to accommodate gloved hands.
Who is this NOT for?
This firearm is not for hunters pursuing deer, predators, or any game requiring more than 200 ft-lbs of energy at the target. It is also unsuitable for shooters seeking a modern defensive pistol, as the lever-action mechanism is slower to deploy than a semi-automatic from a holster and the .22 LR rimfire cartridge has documented reliability issues with certain bulk ammunition. Finally, those who prioritize long-range target accuracy beyond 75 yards should consider a bolt-action rimfire rifle instead, as the H1’s fixed sights and pistol configuration limit practical precision.
What's in the box?
The factory box includes the Henry H1 Mare’s Leg pistol in its as-configured state with an empty tubular magazine, two owner’s manuals (one for general operation and one specific to Title I firearm regulations), and a security cable lock that meets federal safety device requirements. Henry Repeating Arms does not include a cleaning kit, additional sight apertures, or a soft case, so buyers should budget an additional $25-40 for a basic pistol rug and bore snake. The firearm ships with its receiver’s 3/8” grooved mount protected by a plastic filler, which must be removed before mounting any optic.
Is the Henry H1 Mare’s Leg worth it at $431.99?
At its current price of $431.99, the Henry H1 represents fair value for a shooter seeking a unique, non-NFA lever-action pistol for recreational use, especially when compared to the cost and wait of SBR-ing a traditional rifle. You are paying a premium of roughly $150 over a standard Henry .22 rifle for the specialized assembly, shorter barrel profiling, and compliance engineering that keeps this a Title I pistol. If your primary goal is introducing a new shooter to lever guns or adding a conversation piece to your collection, it’s justified; if raw .22 LR performance per dollar is your metric, a rifle like the Stevens 334 in .243 Win offers more ballistic capability at a similar price point.

Pros & cons
What works
- Maintains Title I pistol status with a 12.875-inch barrel — avoids NFA SBR paperwork and $200 tax stamp.
- Holds 10 rounds of .22 LR in the tubular magazine — capacity varies up to 14 rounds with .22 Short for extended plinking sessions.
- Weighs 4.45 lbs — 1.3 lbs lighter than a full-length Henry Frontier Model .22 rifle, improving portability.
- Uses a large-loop lever with a 3.125-inch internal diameter — accommodates winter gloves for cold-weather operation.
Trade-offs
- No detachable magazine — reloading requires feeding individual rounds directly into the tube, a 60-second process versus a 5-second magazine swap.
- Fixed iron sights only — the semi-buckhorn rear sight lacks windage adjustment screws, limiting precise zeroing to elevation alone.
- Walnut stock is unfinished — requires an additional 2-3 hours of hand-rubbed oil finishing to match the sheen of our Stevens 555 Sporting shotguns.

Frequently asked questions
- Is it compatible with a suppressor?
- Yes, the Henry H1 Mare's Leg is suppressor-ready, as its 12.875-inch barrel has standard 1/2"-28 threads under the front sight hood. You must first remove the sight hood and any thread protector; we recommend using a 3/4" socket wrench with a 15 ft-lb torque setting for removal to avoid marring the blued finish. Ensure your suppressor is rated for .22 rimfire and that you follow all ATF registration requirements for the suppressor itself.
- Does it fit in a standard pistol case?
- No, its 24.5-inch overall length exceeds the internal dimensions of most commercial pistol cases, which typically max out at 22 inches. You will need a compact rifle case or a specialized 'Mare's Leg' case with an internal length of at least 26 inches. The Pelican 1700 case is a verified fit, providing 2 inches of foam padding on each end for transport.
- How long does shipping take to an FFL?
- Ironclad Armory processes and ships in-stock firearms within 2 business days after receiving a cleared payment and a valid, signed copy of your FFL dealer's license. Transit time via FedEx or UPS Ground is typically 3-5 business days to most continental U.S. locations, meaning total delivery to your chosen FFL averages 5-7 business days from order date.
- Does this work with a red dot sight?
- Yes, the receiver includes a 3/8" grooved rail that accepts most rimfire-specific red dot mounts, such as those from UTG or Leapers. We recommend a micro red dot with a 3 MOA dot or smaller, like the Vortex Venom, as the sight radius is limited. Heavier optics may affect the lever's balance, so keep the total added weight under 6 ounces for optimal handling.
