Lightweight Rimfire Suppression Done Right

The rimfire suppressor market is crowded with options, but few manage to balance sound reduction, lightweight construction, and easy maintenance the way the Resonance 22 Silencer does. Built by our team at Heresy Design, this suppressor is designed specifically for rimfire shooters who want maximum performance without unnecessary complexity.

Whether you’re running a suppressed .22 LR rifle for small game hunting, quiet range practice, or a suppressed pistol for training, the Resonance 22 offers impressive performance in a compact and affordable package. With a retail price around $299.95, it also sits in a very competitive spot in the suppressor market, making it appealing for both first-time suppressor buyers and experienced shooters looking to add another rimfire can to their lineup.

Below is a detailed review of the design, performance, and real-world benefits of the Resonance 22 Silencer.

Design and Construction

One of the standout features of the Resonance 22 is its high-flow monocore design. Unlike traditional stacked baffle suppressors, the monocore system uses a single precision-machined core that manages gas expansion and sound suppression throughout the entire suppressor body.

This approach offers several advantages:

• Simplified cleaning
• Fewer internal components
• Consistent alignment
• Improved gas flow

Rimfire ammunition is notoriously dirty. Anyone who has shot suppressed .22 LR knows how quickly residue and lead build up inside a suppressor. A monocore design like the one used in the Resonance 22 makes maintenance significantly easier compared to suppressors that use multiple baffles.

The suppressor is constructed using several high-quality materials designed to balance durability and weight:

Core

• 6061-T6 aluminum
• Type II hard anodized finish

Blast Cone

• 416 stainless steel
• Nitride coated for durability

Tube

• 4140 seamless tubing
• Nitride coated

Endcap

• 4140 heat-treated steel
• Nitride coating

Thread Mount

• 17-1 stainless steel

This combination of aluminum and hardened steel allows the suppressor to stay extremely lightweight while still protecting critical components from the blast erosion that occurs with repeated firing.

Ultralight Handling

Weight matters more than many shooters realize when it comes to suppressors. A heavy suppressor can drastically change the balance of a firearm, especially on smaller rimfire rifles and pistols.

The Resonance 22 weighs only 4.2 ounces, making it one of the lighter suppressors in its class.

This ultralight design provides several benefits:

• Minimal impact on firearm balance
• Reduced muzzle fatigue during long shooting sessions
• Better performance on small pistols
• Ideal for lightweight hunting rifles

At 5.9 inches long and 1 inch in diameter, the suppressor also maintains a slim profile that works well on both pistols and rifles without obstructing standard sights.

For shooters running compact rimfire pistols, this lightweight design makes a noticeable difference compared to heavier suppressors.

Sound Suppression Performance

The primary purpose of any suppressor is sound reduction, and the Resonance 22 delivers solid performance in this area.

According to manufacturer specifications, the suppressor averages 112 dB when used with rimfire ammunition.

To put that into perspective:

• Unsuppressed .22 LR can exceed 140 dB
• Many rimfire suppressors land between 110–118 dB

This places the Resonance 22 squarely in the range of high-performing rimfire suppressors.

The suppressor is rated for:

• All rimfire calibers
• Subsonic 5.7mm ammunition

This versatility makes it compatible with a wide variety of firearms, including:

• .22 LR rifles
• .22 LR pistols
• .22 WMR platforms
• .17 HMR rifles
• Subsonic 5.7 firearms

When paired with subsonic ammunition, the result is extremely quiet shooting. In many cases, the loudest noise you’ll hear is the action cycling rather than the muzzle report.

This makes the Resonance 22 ideal for:

• Backyard pest control (where legal)
• Small game hunting
• Discreet range training
• Teaching new shooters at a range or shooting targets recreationally

Reduced Blowback and Cleaner Shooting

One issue that many suppressed firearms experience is excessive blowback. When gas pressure is trapped by a suppressor, it can push residue and gas back into the firearm’s action.

The high-flow monocore design in the Resonance 22 helps mitigate this problem by improving gas movement through the suppressor.

Benefits of reduced blowback include:

• Cleaner firearm operation
• Less gas in the shooter’s face
• Improved reliability on semi-automatic firearms
• Less carbon buildup in the action

For shooters running suppressed rimfire pistols or semi-automatic rifles, this can make a noticeable difference in shooting comfort.

Easy Maintenance

Maintenance is one of the most important factors when choosing a rimfire suppressor.

Rimfire ammo produces:

• Carbon buildup
• Lead fouling
• Powder residue

If a suppressor is difficult to disassemble, cleaning can become a frustrating process.

Fortunately, the Resonance 22 is designed for tool-less servicing, meaning you can easily disassemble it for cleaning without specialized tools.

This is a major advantage for shooters who frequently run large volumes of .22 LR through their suppressors.

Regular cleaning helps:

• Maintain optimal sound suppression
• Prevent carbon lock
• Extend the lifespan of the suppressor

The simple design makes routine maintenance quick and painless.

Durability and Warranty

Suppressors represent a long-term investment, especially when you factor in the additional cost and paperwork required under NFA regulations. Because of this, durability and manufacturer support are extremely important.

The Resonance 22 is backed by a limited lifetime warranty, providing peace of mind for buyers.

The combination of hardened steel blast components and corrosion-resistant coatings ensures the suppressor can withstand thousands of rounds of use without significant wear.

For rimfire shooters who spend a lot of time at the range, this durability is a key selling point.

NFA Considerations

Like all suppressors in the United States, the Resonance 22 is regulated under the National Firearms Act (NFA).

Purchasing one requires:

• Buying through a licensed NFA dealer
• Submitting ATF Form 4
• Receiving a tax stamp (which no longer costs $200)
• Completing a background check

While the process can take several months depending on approval times, suppressor ownership has become increasingly popular among shooters who value hearing protection and reduced noise.

Final Verdict

The Resonance 22 Silencer from Heresy Design delivers exactly what rimfire shooters want in a suppressor:

• Excellent sound suppression
• Extremely lightweight construction
• Easy maintenance
• Reliable durability
• Competitive pricing

Its 4.2-ounce weight, 112 dB sound signature, and tool-free servicing make it a strong contender in the rimfire suppressor category.

Whether you’re suppressing a .22 LR rifle for hunting, building a quiet range setup, or adding a suppressor to a rimfire pistol, the Resonance 22 provides a well-balanced blend of performance and practicality.

For shooters looking for a lightweight, easy-to-maintain rimfire suppressor that doesn’t break the bank, the Resonance 22 is definitely worth considering.
