Key Features

• Octagon barrel, 20.5″ length: The blued octagon profile adds stiffness and mass for improved accuracy, especially with .22 WMR’s higher velocity compared to .22 LR. The 20.5″ length balances swing speed with velocity retention.
• Brasslite receiver with polished brass finish: The Brasslite alloy reduces weight without sacrificing durability, while the polished brass finish provides corrosion resistance and a vintage look that stands out in a safe or on a rack.
• American walnut stock with straight grip: The full-length walnut stock with a straight grip offers a natural point of aim and traditional ergonomics, making it easy to carry for small-game hunts or plinking sessions.
• Adjustable rear sight with brass bead front: The factory sights are windage and elevation adjustable, and the brass bead front provides a fast, high-contrast sight picture in varied lighting—no need for immediate optic upgrade.
• Drilled and tapped receiver for optics: If you prefer a red dot or low-power scope for precision, the receiver is pre-drilled and tapped, saving you a gunsmith trip. The tubular magazine holds 12 rounds of .22 WMR.

Who It’s For

This rifle fits the long-range rimfire shooter who wants to stretch .22 WMR beyond 100 yards, the small-game hunter who values a reliable lever action for squirrels or rabbits, and the collector who appreciates a classic American design with modern manufacturing. It’s also a solid choice for a first lever action—light enough for youth shooters, but accurate enough for experienced marksmen.

Pros & Cons

• Pros: Classic octagon barrel design, Brasslite receiver reduces weight, factory drilled/tapped for optics, 12-round magazine capacity, excellent fit and finish for the price point.
• Cons: The Brasslite receiver, while durable, is not as traditional as a full steel receiver for purists; the straight grip may feel less secure for shooters used to a pistol-grip stock. Also, .22 WMR ammunition is more expensive than .22 LR, which can limit practice volume.

What is the barrel twist rate on the Henry Golden Boy H004M?

Per Henry Repeating Arms specs, the H004M uses a 1:16″ twist rate, which is standard for .22 WMR to stabilize 30- to 40-grain projectiles. This twist works well for both hunting loads and target ammunition.

Can I mount a scope without drilling?

Yes. The receiver is factory drilled and tapped, so you can mount a Weaver-style or Picatinny rail directly without additional gunsmithing. Use a low-profile rail to maintain a cheek weld with the factory stock.

Is the Henry Golden Boy H004M safe for .22 WMR +P loads?

No. Henry does not recommend +P or high-pressure .22 WMR loads in the Golden Boy line. Stick to standard-velocity .22 WMR ammunition to avoid excessive pressure that could damage the action or barrel.

How does the Brasslite receiver hold up over time?

Brasslite is an aluminum-brass alloy that resists corrosion and keeps weight down. The polished brass finish may develop a natural patina with use, but it won’t rust. If you prefer a bright finish, occasional polishing with a brass-safe cleaner is recommended.

What is the length of pull on this rifle?

Per manufacturer specs, the length of pull is 14 inches. This is standard for a full-size lever action and fits most adult shooters without needing a spacer or pad.
