The new Gemtech GM-22 rimfire suppressors is one of the shortest and lightest suppressors we have tested. At 5 inches in length and only 2.5 ounces it is barely noticeable on a .22 rifle and does not affect the balance of a handgun. But how does it perform? Quite well actually.
Is it the absolute quietest rimfire silencer on the market? No, however .22 is not that loud to start. The GM-22 reduces sound signature by 36-39 decibels. Honestly, I could not tell the difference between the GM-22 and several other rimfire suppressors while testing for this review article. Certainly when you drop down into subsonic loads it is whisper quiet. A longer suppressor with more internal volume will be marginally quieter but there is a trade-off in weight and balance.
I ran the GM-22 on a Savage Mark II FV-SR rifle and a Browning Buck Mark pistol. Although I did experience a few malfunctions it was no different failure rate than running without the can. Just the nature of .22 ammo.
- Length: 5 inches
- Weight: 2.5 ounces
- Diameter: 1 inch
- Construction: 7075 aluminum
- Baffle design: Monocore (G-Core with C3 Technology)
- Full-auto rated with .22 long rifle
- Caliber: 22LR, 22WMR, 17HMR
The Gemtech GM-22 is user-serviceable which is a requirement for any rimfire suppressor expected to see even moderate round count. According to Gemtech the C3 Technology is supposed to help prevent as much lead build-up and make for easier cleaning. Rimfire is so dirty that I am all for any solution that helps. The unit I received from the Silencer Shop for testing was a demo can. I only ran about another hundred rounds so I’m not in a position to comment on the long-term benefits of C3. My personal observation was that disassembly was no better or worse than comparable rimfire suppressors as it always seems a bit gritty and tight.
MSRP is $395 but the Silencer Shop has them in stock for $300. At that price and Gemtech quality you can’t go wrong.
