The BANISH 22 suppressor is designed for use with rimfire pistols and rifles chambered in .22 caliber and smaller. This includes .22 Hornet, .17HMR, and even 5.7x28. It's even rated for full-auto! Using 1/2x28 threads for direct attachment, the BANISH 22 is made of lightweight titanium, weighs just 4.1oz, is 1" in diameter, and only 5 " long. This means you'll barely even notice that the BANISH 22 is on the end of your gun - except when it comes to sound reduction. Tests have shown that the BANISH 22 brings the sound down to about 120 decibels, making it barely louder than a BB-gun. Essentially, this is as close to "Hollywood quiet" as you can get. The Banish 22 at the muzzle tested at 116.8 dB on a 22LR with a 16" barrel and 117.6 dB at the muzzle on a Ruger Mark IV. Since rimfire ammo uses projectiles that are not jacketed, lead buildup and carbon fouling are a real concern in a rimfire silencer. Over time without cleaning, it's possible for a .22 suppressor to completely fill with lead and carbon, rendering it ineffective for sound suppression and adding considerable weight. The BANISH 22 was designed specifically to maximize your time shooting and minimize your time cleaning. Inside the tube are eight baffles that are engineered for a precise fit to keep lead debris and carbon buildup at an absolute minimum. This prevents the debris and buildup from reaching the tube, which causes components to fuse together. Once disassembled, cleaning couldn't be simpler: toss the baffles in a tumbler, ultrasonic cleaner, or use good, old-fashioned elbow grease. With indexing lines on each baffle for easy realignment and reassembly, the BANISH 22 is the only rimfire silencer on the market that is user-serviceable from both ends. If you're looking for the perfect first-time silencer purchase, the BANISH 22 is a great option. It's ideal for varmint shooting, small game hunting, target practice, and more.
