For shooters who enjoy quiet and affordable range sessions, rimfire suppressors are often the most popular option. The GM‑22 Rimfire Suppressor from Gemtech was designed specifically for that purpose providing lightweight sound suppression for rimfire firearms used in target shooting and recreational plinking.
Rimfire suppressors are especially appealing because they pair extremely well with low-recoil cartridges like .22 LR, producing a very quiet shooting experience while keeping operating costs low. When combined with a rimfire pistol such as the Browning Buck Mark, the result is a compact and enjoyable setup that many shooters use for casual range practice.
One of the most notable characteristics of the GM-22 is its extremely light weight. Weighing only about 2.7 ounces, the suppressor adds minimal weight to a firearm, allowing shooters to maintain natural balance and handling.
This makes it particularly well suited for small pistols and lightweight rifles. Rimfire firearms are typically designed to be compact and easy to handle, so a suppressor that does not significantly alter the firearm’s feel is a major advantage.
The suppressor is also relatively compact, measuring about 5 inches in length and 1 inch in diameter, making it easy to transport and use without adding excessive bulk to the firearm.
The GM-22 uses what is known as a unicore design, a modern suppressor construction method that simplifies both manufacturing and maintenance.
Traditional suppressors often consist of a tube filled with multiple individual baffles. Each baffle must be removed, cleaned, and reinstalled separately. This process can become difficult after extended use because rimfire suppressors accumulate significant amounts of powder residue and lead deposits.
With a unicore design, however, the internal baffle structure is machined from a single piece of metal rather than a stack of individual components. In the GM-22, the core is machined from 7075-T6 aluminum, forming a solid internal structure that includes all the necessary baffles.
This design offers several advantages:
The suppressor’s thread insert, which attaches to the firearm’s barrel, is made from titanium. Titanium provides greater strength than aluminum and helps prevent wear when repeatedly threading the suppressor onto steel barrels.
Cleaning is particularly important for rimfire suppressors because .22 LR ammunition produces significant residue. Powder fouling and bullet material can quickly accumulate inside the suppressor, increasing weight and reducing performance if left unchecked.
The GM-22’s unicore design makes this process easier. Instead of removing a stack of fragile baffles, the user simply removes the outer tube and cleans the single internal core.
Many shooters clean the suppressor using:
The outer aluminum tube itself typically requires only basic cleaning, such as brushing and solvent rinsing.
The GM-22 attaches using the common ½×28 threaded barrel pattern, which is widely used on rimfire pistols and rifles. Installing the suppressor is straightforward: remove the firearm’s thread protector and screw the suppressor onto the barrel.
However, when removing the suppressor, users should grip the rear portion of the internal core rather than the outer tube. The core features small scallops that provide better grip. This prevents accidentally unscrewing the outer sleeve from the core instead of removing the suppressor from the firearm.
Rimfire suppressors are known for delivering impressive sound reduction because the .22 LR cartridge is already relatively quiet compared with larger calibers. The GM-22 typically provides 36–39 decibels of sound reduction, significantly reducing the report of a rimfire firearm.
When paired with a handgun like the Browning Buck Mark, the suppressor produces a noticeably quieter shooting experience. Although pistols tend to be slightly louder than rifles due to higher muzzle pressure, the sound reduction still makes for a comfortable and enjoyable range session.
During testing, the suppressor showed little to no noticeable shift in point of impact at typical handgun distances, meaning shooters can expect consistent accuracy when using the suppressor.
Like many unicore suppressors, the GM-22 may occasionally exhibit a phenomenon known as first-round pop. This occurs when oxygen inside the suppressor ignites during the first shot, producing a slightly louder report.
After the first shot, the remaining oxygen is displaced by combustion gases, and subsequent shots become quieter. This effect is common with many suppressor designs and does not affect the overall performance of the suppressor during extended shooting.
Key specifications for the GM‑22 Rimfire Suppressor include:
The GM‑22 Rimfire Suppressor from Gemtech is designed to maximize the enjoyment of rimfire shooting. With its lightweight construction, simple maintenance, and effective sound reduction, it offers an accessible suppressor option for shooters who want a quieter and more comfortable plinking experience.
Because rimfire ammunition remains one of the most affordable types of ammunition available, pairing a rimfire firearm with a suppressor like the GM-22 can create an exceptionally enjoyable range setup for both new shooters and experienced enthusiasts alike.
