Description

Let me tell you about the first time I finished a muzzleloader kit. There’s a quiet pride that comes from holding a rifle you built, a direct link to a different era of shooting. That’s the experience the Lyman Cap Lock 54 32″ Barrel Adjustable Hardwood Stock #11 Percussion Kit delivers. It’s not just a gun; it’s a project that ends with a serious, accurate, traditional muzzleloader you’ll use for years.

So, what is it? The Lyman Cap Lock 54 is a build-it-yourself percussion rifle kit chambered in .54 caliber. It features a 32-inch precision-rifled barrel, an adjustable hardwood stock for custom fit, and uses standard #11 percussion caps. This kit provides the core components to assemble an authentic, high-quality black powder rifle, offering a deeply satisfying hands-on shooting experience.

I’ve put plenty of rounds downrange with finished Lyman rifles, and the .54 caliber is a favorite. It has real authority for hunting, yet it’s manageable to shoot. The 32-inch barrel isn’t just for looks—it gives that long sight radius that makes precision shooting intuitive and helps wring out every bit of velocity from your powder charge. The adjustable hardwood stock is a standout feature. You can tailor the length of pull to fit you, which is a huge advantage for consistent shooting. It’s a feature you usually have to pay a gunsmith to add later.

The build process itself is part of the appeal. You’re fitting and finishing the stock, installing the barrel and lock, and applying the final finish. The good news? It’s designed to fit out of the box. No complex inletting or major gunsmithing is required; it’s about careful sanding, staining, and assembly. You end up with a rifle that’s uniquely yours. At a price of $491.42, you’re getting a lot of rifle for the money, especially considering the quality of the Green Mountain barrel and the adjustable stock system.

Pros & Cons
Here’s the thing—the pros are compelling. You get a custom-fitted rifle, the deep satisfaction of building it yourself, and a fantastically accurate traditional muzzleloader built around a proven barrel. The .54 caliber is versatile for target and game. The con? It requires time and patience. You need basic tools and a weekend or two. It’s also a single-shot, obviously, so rate of fire is measured in minutes, not rounds per minute. That’s part of the charm, though.

Who is this kit for? It’s perfect for the shooter who wants to step into black powder with a quality rifle they had a hand in creating. It’s for the hunter seeking a Missouri whitetail or turkey season challenge. It’s also ideal for the history enthusiast or the tinkerer who enjoys woodworking. If you appreciate the process as much as the result, this is your kit. This product is available at firearms-missouri.com for Missouri residents and nationwide, following all applicable regulations.

Frequently Asked Questions

Q: What tools and supplies do I need to complete this kit?

A: You’ll need basic woodworking tools like sandpaper, files, and screwdrivers, along with wood stain and finish (like Tru-Oil or a similar gunstock oil). A vise with padded jaws is very helpful. The kit includes all the major firearm components—barrel, lock, stock, hardware, and ramrod.

Q: Is this rifle suitable for hunting in Missouri?

A: Absolutely. The .54 caliber is more than adequate for deer, bear, and turkey within the ranges appropriate for muzzleloaders. Always check the current Missouri Department of Conservation regulations for specific seasons and legal requirements for muzzleloading hunting.

Q: What accessories will I need to shoot it?

A: You’ll need black powder or a substitute like Pyrodex, .530 or .535 round balls or conical bullets, patches, #11 percussion caps, a powder measure, and cleaning supplies. A starter kit from a brand like CVA or Traditions will cover most essentials to get you going.

If you’re ready for a rewarding project that ends with a rifle you’ll be proud to own and shoot, the Lyman Cap Lock 54 kit is waiting for you.
