If you’re a rimfire enthusiast, collector, or someone searching for a dependable and budget-friendly semi-auto rifle, the Marlin 99C .22LR deserves your attention. While this model isn’t in production anymore, it still commands respect for its durability, accuracy, and classic American styling. When found as a police trade-in rifle, it represents exceptional value—a reliable, well-maintained firearm with historical and practical appeal.

In this in-depth guide, we’ll take a closer look at the Marlin 99C’s history, specifications, performance, and unique features. We’ll also explain why law enforcement agencies might have used this rimfire rifle, what to look for in a used model, and how it compares to other .22 rifles on the market today.

Overview of the Marlin 99C .22LR

The Marlin Model 99C is a classic .22 caliber semi-automatic rifle, built with the kind of old-school craftsmanship that defined American firearms during the mid-20th century. Manufactured from the late 1950s through the early 1980s, the 99C was part of Marlin’s lineup of affordable and reliable rimfire rifles.

The “C” in 99C stands for Clip, referencing the rifle’s detachable magazine. Unlike many of Marlin’s other .22s (such as the Model 60, which uses a tubular magazine), the 99C utilizes a box magazine, typically holding 7 rounds of .22LR. This setup offers quick reloading and a more convenient unloading process, which may explain why it was sometimes adopted or kept in inventory by police departments for training or utility purposes.

Why a Police Trade-In .22LR?  Marlin 99C 22LR Police Trade-In Rifle

At first glance, it might seem odd that law enforcement agencies would have used or stocked a .22LR semi-auto rifle like the Marlin 99C. However, there are several valid reasons why this model may have appeared in police armories:

1. Training Use

Police departments often use .22LR rifles for basic firearms training, especially for new recruits or for introductory firearms courses in schools or public outreach programs. The low recoil, affordable ammunition, and user-friendly handling make the 99C a perfect candidate for this role.

2. Small Game Control

Some rural or wildlife enforcement units occasionally use rimfire rifles for pest control, dispatching injured animals, or dealing with nuisance wildlife around public facilities.

3. Budget Utility Firearm

Law enforcement agencies with limited budgets might acquire or retain rimfire rifles for utility or backup use. A .22LR like the 99C offers a cost-effective tool for non-critical firearm needs.

When these rifles are phased out, they often re-enter the civilian market as police trade-ins, typically well-maintained and lightly used.

Key Features of the Marlin 99C .22LR

1. Detachable Magazine

The most distinguishing feature of the 99C compared to other Marlin .22 models is its detachable box magazine, typically holding 7 or 10 rounds. This design makes reloading quick and convenient, which is ideal for new shooters, plinkers, or training use.

2. Micro-Groove Barrel

One of Marlin’s signature innovations, the Micro-Groove rifling, is a hallmark of the 99C’s accuracy. Introduced in the 1950s, this barrel technology features multiple shallow grooves (instead of fewer deep ones), providing smoother bullet travel and less fouling. The result is improved accuracy and longer barrel life, especially with lead .22LR bullets.

3. Solid Wood Stock

True to its era, the 99C features a walnut-finished hardwood stock, adding to its classic aesthetic and balanced feel. The full-sized stock gives it a more substantial presence than many of today’s synthetic rimfire rifles.

4. Reliable Semi-Auto Action

The rifle operates via blowback semi-automatic action, a simple and time-tested mechanism that cycles reliably with standard or high-velocity .22LR ammunition. The charging handle and manual safety are easy to manipulate, making the 99C accessible for both seasoned shooters and beginners.

5. Grooved Receiver for Optics

Though it comes with adjustable iron sights, the receiver is grooved for tip-off scope mounts, allowing you to easily add a rimfire scope without drilling or gunsmithing. Many users enjoy pairing the 99C with a 3-9x rimfire optic for target shooting or squirrel hunting.

Performance and Shooting Experience Marlin 99C 22LR Police Trade-In Rifle

While not a target-grade rifle by today’s match standards, the Marlin 99C is known for its reliable cycling, solid accuracy, and comfortable handling. With quality ammunition, it’s common to achieve 1.5 to 2-inch groups at 50 yards with iron sights—and even better with optics.

Thanks to its Micro-Groove barrel, the 99C generally prefers standard to high-velocity lead round nose or hollow point ammo. It’s less picky than some modern rimfires and rarely suffers from feeding issues if the magazine and chamber are kept clean.

Recoil is virtually nonexistent, and follow-up shots are smooth and quick. That makes the 99C ideal for plinking, target practice, small game hunting, and introducing new shooters to firearms in a low-stress setting.

Benefits of a Police Trade-In Marlin 99C

1. Proven Reliability

Police departments tend to maintain their firearms to a higher standard than the average user. Even older trade-ins are often in better mechanical shape than civilian rifles of the same vintage.

2. Affordability

Because these rifles are used and surplus, police trade-ins of the Marlin 99C are typically offered at very budget-friendly prices, often under $200. That’s excellent value for a reliable semi-auto rimfire with classic looks and solid performance.

3. Historic Character

Each police trade-in has a story. Whether it served in a training program, was used by wildlife officers, or sat in an armory for years, it carries a piece of history with it. That adds character and value to collectors and enthusiasts.

Things to Check When Buying a Used Marlin 99C

Before purchasing a used or police trade-in Marlin 99C, keep these inspection tips in mind:

– Barrel and Bore Condition

Use a bore light or flashlight to inspect the rifling. Micro-Groove barrels should have clean, sharp grooves. Check for pitting, rust, or excessive fouling.

– Magazine Fit and Function

Original magazines are best, but replacements are available. Test the mag for secure fit, smooth feeding, and proper lock-up.

– Bolt and Action Cycling

The bolt should cycle smoothly, and the action should lock back when empty. Test the trigger for creep and ensure the safety works correctly.

– Stock Integrity

Inspect the hardwood stock for cracks, chips, or warping. Refinished stocks are common and not necessarily a dealbreaker, but cracks near the receiver or action are a red flag.

– Overall Wear

Some cosmetic wear is expected, but make sure there’s no major corrosion or signs of structural damage. A little finish wear or thinning bluing adds character without affecting function.

Best Uses for the Marlin 99C .22LR

1. Plinking and Target Shooting

The 99C is perfect for weekend fun at the range. It’s accurate, easy to shoot, and cheap to feed, making it a go-to plinker.

2. Small Game Hunting

With a properly sighted-in optic and quality hollow point ammo, the 99C is more than capable of dispatching rabbits, squirrels, and other small game.

3. Training and Youth Shooting

Its mild recoil, simple controls, and light weight make the 99C an excellent training rifle for new shooters or youth participants under supervision.

4. Collection and Preservation

As a discontinued model from one of America’s most storied firearm manufacturers, the 99C is a fine addition to any rimfire or vintage gun collection—especially when purchased as a unique police trade-in.
