YHM Phantom .22 Rimfire Suppressor (YHM-4380) Review & Specs: Lightweight 5.5" Can for .22LR, .17 HMR, .22 Mag & 5.7x28
YHM Phantom .22 Rimfire Suppressor (YHM-4380): Lightweight, User-Serviceable Performance for .22LR to 5.7x28
Introduction
If you’re shopping for a rimfire suppressor that stays light on a pistol, remains compact on a rifle, and is still rated for more than “just .22LR,” the YHM Phantom .22 Rimfire Suppressor is built to check those boxes. This model (MPN YHM-4380) is designed around a simple idea: deliver strong rimfire suppression and easy maintenance in a package that won’t turn your favorite plinker into a muzzle-heavy chore.
From a buyer’s perspective, rimfire cans live or die by three things: weight, serviceability (because rimfire is filthy), and real-world durability. The YHM Phantom .22 Rimfire Suppressor aims at the sweet spot by combining lightweight aluminum outer components with a robust 17-4 stainless baffle stack—and it does so in a very handy 5.5-inch form factor.
Key Features and Specifications
Below are the core specs and design details that matter when you’re deciding whether this is the right rimfire can for your hosts.
Core dimensions and weight
- Overall length: 5.5 in
- Diameter: 1.1 in
- Weight: 4.0 oz
That 4-ounce weight is a major win for balance—especially on rimfire pistols where an extra few ounces can make the gun feel sluggish during transitions or extended range sessions.
Materials and construction (why it matters)
The YHM Phantom .22 Rimfire Suppressor uses a mixed-material approach:
- Baffle stack: heat-treated 17-4 PH stainless steel
- Outer assembly: aluminum components (blast chamber and tube)
- Rear thread insert: stainless steel 1/2x28 insert to extend mounting thread life
This combination is practical: stainless baffles tolerate aggressive fouling and repeated cleanings better than all-aluminum stacks, while the aluminum tube keeps the overall weight low.
Mounting / threading
- Mount type: direct-thread
- Thread: 1/2x28
Direct-thread rimfire suppressors remain the simplest and most common option, and for many shooters they’re the most “grab-and-go” setup for swapping between a threaded .22 pistol and a 10/22-style rifle.
Caliber rating and barrel-length minimums
The YHM Phantom .22 Rimfire Suppressor is rated up through 5.7x28mm, with published minimum barrel lengths:
- .22 LR: no restrictions
- .22 WMR (.22 Mag): 10 in minimum
- .17 HMR: 10 in minimum
- 5.7x28mm: 10 in minimum
For shoppers planning on occasional 5.7 use, those barrel-length notes are not a footnote—they’re a primary compatibility check.
Suppression (manufacturer-rated)
YHM lists a decibel rating of 115 dB for the YHM Phantom .22 Rimfire Suppressor. Keep in mind that “dB numbers” vary dramatically depending on test setup, ammo, barrel length, and measurement location, but the key takeaway is that YHM positions this suppressor as a high-performing rimfire option—not merely a compact “noise reducer.”
Maintenance-friendly design details
Rimfire suppressors inevitably accumulate carbon and lead. YHM’s design includes:
- A shielded interlocking baffle stack intended to keep fouling contained
- Indexing tabs on baffles to help ensure correct orientation during reassembly
- A clever feature where the rear of the blast chamber serves as the takedown tool for the muzzle cap—meaning you’re less likely to be stranded without a way to open the can for cleaning
Those features are specifically aimed at reducing the most common rimfire suppressor headache: a baffle stack that gets so fouled it seizes in place.
Practical Applications
A rimfire suppressor should make your shooting more enjoyable and more consistent—not add complications. Here’s where the YHM Phantom .22 Rimfire Suppressor tends to shine.
1) Rimfire pistols (.22LR) for training and range comfort
On hosts like popular polymer-framed .22 pistols, weight is everything. At ~4 ounces, this suppressor is well suited for:
- introducing new shooters with reduced blast and improved comfort
- improving shot-to-shot focus during drills
- extended plinking sessions with less fatigue
2) Rimfire rifles for quiet plinking and small-game utility
On a 10/22-style rifle, the 5.5-inch length keeps the package maneuverable. Pairing the suppressor with subsonic or standard-velocity ammunition often yields the “classic” rimfire-suppressed experience: reduced report, less perceived concussion, and easier communication on the firing line.
3) Versatile use across .17 HMR / .22 Mag / 5.7x28 (within limits)
A big differentiator is the ability to use the same can across several small-caliber cartridges—helpful if you want one rimfire suppressor that can cover multiple niche hosts. The published minimum barrel lengths for .17 HMR, .22 Mag, and 5.7x28 are critical here: if your host is shorter than 10 inches in those calibers, this is not the right match.
4) High-round-count ownership (why serviceability is non-negotiable)
Rimfire ammo is dirty, and lead buildup is real. User-serviceable construction is what turns a rimfire suppressor from a “temporary novelty” into a long-term tool you can run hard.
Expert Analysis
From a product-research standpoint, the YHM Phantom .22 Rimfire Suppressor sits in a very intentional position in the market: lightweight, compact, stainless-baffled, and explicitly designed to be easy to open and maintain.
What I like most about the design
- Weight-to-rating balance: A 4 oz can rated up through 5.7x28 (with restrictions) is meaningful for shooters who prioritize handling.
- Stainless baffles: 17-4 PH stainless is a strong choice for longevity and repeated cleaning cycles.
- Thoughtful takedown approach: Integrating the takedown tool into the suppressor’s components is a practical “field maintenance” advantage.
Cleaning guidance (practical and safety-first)
A few best practices matter for almost any rimfire suppressor owner:
- Clean on a schedule that prevents seizing: Many experienced users treat “every range trip” or roughly a few hundred rounds as a reasonable baseline for rimfire maintenance.
- Know your materials before chemical cleaning: Certain aggressive solutions can be unsafe for aluminum parts; always follow the manufacturer’s guidance and the owner’s manual.
- Use PPE and good hygiene: Lead exposure is a real concern when servicing rimfire suppressors—gloves, ventilation, and careful cleanup are smart habits.
Pricing and availability (verified)
The manufacturer’s current listing shows the YHM Phantom .22 Rimfire Suppressor at $439.95 on YHM’s site (as of the page update shown on their product listing). Note: YHM also states they do not sell serialized suppressors direct to end users; purchases typically go through appropriately licensed dealers.
Conclusion
The YHM Phantom .22 Rimfire Suppressor (MPN YHM-4380, UPC 841812101222) is a strong option for shooters who want a compact, extremely lightweight rimfire can that remains user-serviceable and durable where it counts. Its 5.5-inch length and 4-ounce weight make it especially attractive for rimfire pistols, while the stainless baffle stack and shielded design target the real-world maintenance challenges that come with dirty rimfire ammo.
If your priority is “one suppressor that handles beautifully on a .22 pistol, works great on a rimfire rifle, and still gives you flexibility up through 5.7x28 (with barrel-length minimums),” the YHM Phantom .22 Rimfire Suppressor is purpose-built for that role.
