GForce Arms Quietflow 22-Whistler Features The Quietflow 22-Whistler is built from 17-4 stainless steel and 7075 aluminum across 11 baffles giving it the durability needed for sustained rimfire use while keeping weight down to just 6.6 oz. Unlike a sealed non-serviceable design the 22-Whistler comes apart for cleaning letting shooters remove carbon and lead buildup that accumulates from rimfire ammunition over time. Rated across .22 LR .22 WMR .17 HMR and 5.7x28 FN it gives shooters a single suppressor that covers the most common rimfire and sub-caliber platforms. For shooters who want to maintain suppressor performance over the long term the 22-Whistler's serviceable construction keeps internal fouling from degrading sound reduction. Mounting is handled through a straightforward 1/2-28 direct thread interface letting shooters install the suppressor directly onto a compatible threaded barrel without additional adapters. In-house testing from October 2026 measured the 22-Whistler at -24.9 dB at the muzzle and -20.3 dB at the shooter's ear on .22 LR subsonic ammunition fired from a 16.5 inch rifle barrel. For rimfire shooters who want a suppressor they can clean and maintain without replacing the entire unit the 22-Whistler's take-apart design delivers long-term value for sale at GrabAGun.
