Keystone KSAM38 Mini Mosin M38 Carbine .22 LR Single-Shot

The Keystone KSAM38 Mini Mosin M38 Carbine .22 LR Single-Shot is a scaled, fixed-stock rimfire replica of the classic Mosin-Nagant M38 carbine. Chambered in .22 Long Rifle, this single-shot bolt action packs the look, weight, and handling of a historical military rifle into a compact, youth- and trainer-friendly package. The walnut stock and blued metal finish deliver period-correct aesthetics, while the threaded barrel (with protective cap) adds modern muzzle-device compatibility.

Key Features

• Threaded Barrel with Protective Cap – The factory-threaded muzzle accepts standard .22 LR muzzle brakes, suppressors, or flash hiders. The included cap keeps threads clean when not in use.
• Authentic Mosin-Nagant M38 Carbine Styling – Full-length walnut stock, blued metal, and a scaled receiver mimic the original carbine’s profile and balance, making it ideal for historical enthusiasts or as a training analog.
• Single-Shot Bolt Action – Simple, manual cycling reinforces marksmanship fundamentals. No magazine to lose or feed issues to chase — perfect for teaching trigger discipline and shot placement.
• Compact Overall Length – At roughly 36 inches, the KSAM38 is short enough for smaller shooters or tight vehicle storage yet retains a stable sight radius for accurate plinking and small-game hunting.
• Fixed Sights with Adjustable Rear – The rear sight is drift-adjustable for windage and elevation, letting you zero for your preferred .22 LR load without tools.

Who It’s For

The KSAM38 Mini Mosin is built for three distinct shooters: youths transitioning from BB guns to rimfire, adult collectors wanting a safe-to-shoot Mosin replica, and precision trainers who value single-shot discipline. If you own a full-size Mosin-Nagant and want a rimfire companion for cheap practice, this carbine delivers identical manual of arms at a fraction of the cost per round.

Pros & Cons

• Pro: Authentic military-style stock and metal finish for under $350 — one of the most affordable historical-replica rimfires on the market.
• Pro: Threaded barrel ready for suppressors or brakes out of the box.
• Con: Single-shot action limits follow-up speed; not suitable for rapid-fire drills or competition stages requiring multiple targets.
• Con: Fixed stock means no length-of-pull adjustment — taller shooters may find the 13-inch LOP a bit short.

Frequently Asked Questions

What is the barrel twist rate on the Keystone KSAM38?

Per Keystone Sporting Arms specs, the KSAM38 uses a 1:16-inch twist rate, optimized for standard-velocity and high-velocity .22 LR ammunition.

Does the KSAM38 come with a scope rail or dovetail?

No — the receiver is not drilled or grooved for optics. The rifle is designed for use with the factory iron sights only. Aftermarket rail installation would require drilling and tapping by a gunsmith.

Is this rifle legal in all 50 states?

Yes. As a .22 LR single-shot bolt action, the KSAM38 is not restricted under any federal or state assault-weapon bans. It ships to all 50 states with no additional requirements.

Can I mount a suppressor on the threaded barrel?

Yes — the 1/2×28 TPI threads accept standard .22 LR suppressors. Ensure your suppressor is rated for rimfire use and that you comply with all NFA regulations.

Why Choose the Keystone KSAM38?

According to the National Shooting Sports Foundation, .22 LR rimfire rifles account for over 40% of all rifle sales in the U.S. — the KSAM38 fills a specific niche as a historically accurate, budget-friendly trainer that teaches the fundamentals without breaking the bank. Its walnut stock and blued finish are uncommon at this price point, and the threaded barrel adds modern utility. If you want a Mosin-style carbine that your kids can shoot safely and you can enjoy at the range without surplus ammo headaches, this is it.
