Experience Unparalleled Silence with the CZ Rimfire Integral Suppressor .17 HMR 20.9" Barrel

Imagine a shooting experience so quiet, the loudest sound is merely the click of your firearm's action. This is the reality offered by the innovative CZ Rimfire Integral Suppressor .17 HMR 20.9" Barrel. Designed for discerning shooters who prioritize discretion, performance, and a refined shooting environment, this integral barrel and suppressor combination redefines what's possible in rimfire acoustics. For anyone seeking to minimize noise pollution during target practice, engage in discreet pest control, or simply enjoy the subtle pleasures of shooting without disturbing others, this specialized barrel assembly represents a pinnacle of firearm engineering.

The beauty of this system lies in its seamless integration. From an external perspective, the suppressor is virtually undetectable, appearing as a standard, slightly heavier varmint barrel. Its true nature, however, is revealed the moment the trigger is pulled. With the appropriate sub-sonic ammunition, the typical, sharp report of a .17 HMR cartridge is transformed into a whisper, often quieter than the mechanical sounds of the rifle itself. This remarkable acoustic performance is not just a luxury; it's a game-changer for backyard plinking, quiet range sessions, and effective small game or varmint management in noise-sensitive areas.

Precision Engineering: The Core of Quiet Performance

At the heart of this revolutionary design is its integration into one of CZ's renowned 455 Varmint barrels. The CZ 455 platform is already celebrated for its exceptional accuracy, robust construction, and modularity, making it an ideal candidate for such an advanced suppression system. Unlike traditional suppressors that attach to the muzzle, this integral design ensures perfect alignment, optimal balance, and a streamlined profile that enhances handling and aesthetics. The barrel itself retains a substantial .866-inch diameter, typical of CZ's Varmint series, but through clever internal hollowing and the use of lightweight suppressor components, the overall weight is remarkably managed, even with its generous 20.9-inch length.

This careful design ensures that shooters experience reduced muzzle blast and minimized sound, contributing to a more comfortable and focused shooting session. The integral nature means there's no additional length added beyond the barrel itself, maintaining the rifle's overall maneuverability and balance, which is crucial for precision shooting disciplines or navigating tight spaces in the field.

The Patented Screw-In Baffle System: A Revolution in Suppressor Design

What truly sets the CZ Rimfire Integral Suppressor apart is its patented screw-in baffle system. This ingenious design empowers the owner with an unprecedented level of control and customization over their sound suppression. Using an included specialized tool, shooters can thread individual baffles into pre-designated, precision-machined locations within the forward, threaded suppressor portion of the barrel. This isn't just about assembly; it's about active tuning.

The ability to tune baffle lengths allows experienced users to experiment and find the optimal combination for their specific load of choice. Different ammunition types, especially varying bullet weights and velocities within the .17 HMR caliber, can exhibit slightly different sound signatures. With this system, you can fine-tune the gas expansion chambers to achieve the absolute quietest report for your preferred ammunition, whether it's a high-velocity hunting round or a specialized sub-sonic option designed for maximum stealth. This level of user-configurability is rare in the suppressor market and speaks to CZ's commitment to advanced firearm technology and user empowerment.

Beyond tunability, the baffles and the endcap are precisely cut from 7075 aluminum. This aerospace-grade aluminum is known for its exceptional strength-to-weight ratio, making the suppressor components both durable and remarkably light. The use of such high-quality materials ensures longevity and consistent performance, even under repeated firing and rigorous cleaning cycles.

Effortless Maintenance: Designed for Longevity and Performance

One of the most significant challenges with rimfire suppressors is the accumulation of carbon and lead fouling, a byproduct of rimfire ammunition's inherently dirty nature. Traditional suppressors can be notoriously difficult to clean, often requiring specialized tools or soaking for extended periods. CZ has ingeniously addressed this common issue with a unique (and patented) baffle thread design. This innovative thread pattern is engineered to actively cut through accumulated crud during disassembly, making routine cleaning far simpler and more effective.

For optimal performance and to preserve the lifespan of your integral suppressor, CZ recommends cleaning it every 300 rounds. This regular maintenance schedule, made manageable by the smart baffle design, prevents excessive buildup that could otherwise degrade sound suppression capabilities or even cause damage over time. Proper cleaning ensures that your CZ Rimfire Integral Suppressor continues to deliver its exceptional quiet performance shot after shot, year after year. For thorough cleaning, users typically employ a combination of bore solvents, carbon removers, and soft brushes, ensuring all residue is removed from the baffle surfaces and internal barrel channels.

Key Advantages and Use Cases for the CZ Rimfire Integral Suppressor

The integration of a suppressor directly into the barrel offers several compelling benefits over traditional thread-on designs, making it an ideal choice for various shooting applications:

• Unmatched Discretion: The sleek, integrated profile means no additional length is added to the rifle, maintaining a compact and balanced feel. This makes it ideal for discreet pest control or hunting in areas where minimal visual impact is desired.
• Superior Balance and Handling: By incorporating the suppressor into the barrel, the rifle's center of gravity remains optimized, leading to a more natural point of aim and easier maneuverability compared to having a heavy suppressor hanging off the end of a shorter barrel.
• Simplified NFA Compliance: In the United States, an integral suppressor barrel typically counts as a single NFA item, simplifying the registration process compared to acquiring a separate barrel and suppressor. (Always consult local and federal regulations.)
• Reduced Noise Signature: Drastically reduces the decibel output, protecting hearing, reducing flinch, and making shooting more enjoyable for the shooter and less disruptive for bystanders. This is invaluable for training new shooters, allowing them to focus on fundamentals without the intimidation of loud muzzle blast.
• Enhanced Accuracy: The fixed, integral design eliminates potential issues of misalignment or loosening that can sometimes occur with thread-on suppressors, contributing to consistent accuracy.
• User-Tunable Performance: The patented screw-in baffle system allows for fine-tuning of sound reduction based on ammunition type, offering a customized shooting experience.

Consider the applications: for the farmer dealing with persistent varmints, the ability to quietly dispatch pests without startling livestock or neighbors is invaluable. For the target shooter, hours spent at the range become far more comfortable and less fatiguing, allowing for longer, more focused practice sessions. For the hunter of small game, the reduced noise can prevent spooking nearby animals, increasing success rates. This integral barrel system truly transforms the rimfire experience.

About CZ: A Legacy of Precision and Innovation

The name ‘Ceská zbrojovka’ translates directly to ‘Czech armory,’ a testament to a rich and storied history of firearm manufacturing. While many ‘CZs’ existed across the region at various points, our sister company, Ceská zbrojovka a.s. Uherský Brod, stands as a beacon of Czech engineering excellence. Its origins trace back to 1936, established as a strategic branch plant of Ceská zbrojovka Strakonice. Production officially commenced on January 2, 1937, with an immediate dual focus on both crucial military armaments and civilian firearms. The initial output included sophisticated aircraft machine guns, reliable military pistols, and precision small-bore rifles, laying the groundwork for a legacy of quality.

The period of World War II presented immense challenges, as the plant fell under Nazi occupation, forcing its production and repair efforts to serve military objectives alien to its founding principles. However, with the liberation of Czechoslovakia, the plant resiliently returned to its original mission: producing both military and civilian arms in equal measure, rebuilding its reputation for versatility and quality.

A pivotal moment arrived in 1950 when the Company transitioned into a separate state enterprise, officially named ‘Presné strojírenství Uherský Brod’ (The Precision Machine Tooling Company, Uherský Brod). This reorganization into a number of specialized departments allowed for a deeper focus on precision manufacturing and the diversification of its product lines, solidifying its role as a leader in advanced mechanical engineering.

The 1970s and 1980s saw further evolution through a strategic merger with Agrozet Brno. This expansion allowed CZ not only to continue its esteemed tradition of firearm manufacturing but also to venture into diverse industrial sectors. The company began producing reduction gears and driveshaft casings for aircraft engines for Motorlet Praha, showcasing its metallurgical and machining prowess. Furthermore, it contributed significantly to the agricultural sector by manufacturing hydraulically powered and controlled tractor attachments for Zetor Brno, demonstrating its adaptability and broad engineering capabilities. This rich history of precision, innovation, and adaptability is deeply embedded in every product CZ creates, including the sophisticated integral suppressor barrel, ensuring that you are investing in decades of proven expertise and unwavering commitment to quality.

Frequently Asked Questions about Integral Suppressors

What is an integral suppressor?
An integral suppressor is a firearm component where the sound-reducing baffles and expansion chambers are built directly into or around the barrel itself, rather than being a separate device threaded onto the muzzle. This results in a more compact, balanced, and aesthetically pleasing firearm.

Is the CZ Rimfire Integral Suppressor legal?
Yes, integral suppressors are legal for civilian ownership in most states where suppressors are permitted, but they are regulated under the National Firearms Act (NFA) of 1934. This means they require a federal tax stamp, a background check, and transfer through a Class 3 Federal Firearms License (FFL) dealer like DEGuns.com. It is crucial to be aware of and comply with all federal, state, and local laws regarding suppressor ownership.

How does it compare to a traditional thread-on suppressor?
Integral suppressors generally offer a more compact overall length for the firearm, improved balance, and a cleaner aesthetic. They also often provide excellent sound reduction because the entire barrel length can be utilized for gas expansion. Thread-on suppressors, while versatile and transferable between multiple firearms (if compatible), add length to the barrel and may alter a rifle's balance point more significantly.

What kind of ammunition should I use for best results?
For maximum sound reduction, especially with rimfire suppressors, using "sub-sonic" ammunition is highly recommended. Sub-sonic ammunition travels below the speed of sound (approximately 1125 feet per second at sea level), eliminating the supersonic crack that occurs when a bullet breaks the sound barrier. While the .17 HMR is primarily a supersonic cartridge, some specialized sub-sonic loads exist, or even standard velocity loads become very quiet due to the integral design's efficiency. Even with supersonic loads, the integral suppressor will significantly reduce muzzle blast.

How often should I clean the integral suppressor?
CZ recommends cleaning the integral suppressor every 300 rounds due to the dirty nature of rimfire ammunition. Regular cleaning prevents carbon and lead buildup from degrading performance or causing damage. Thanks to CZ's patented baffle thread, this cleaning process is significantly easier than with many other designs.

Can I install this barrel on any CZ 455?
This integral suppressor barrel is designed as a direct replacement for CZ 455 Varmint barrels. While the CZ 455 platform is known for its modularity, professional gunsmith installation is recommended to ensure proper fit, function, and safety, especially with NFA items. Always confirm compatibility with your specific CZ 455 model before purchase or installation.
