The Bowers Group USS .22 (User Serviceable Suppressor) is suitable for everything from both common .17 rimfires, 17 WSM .22LR, .22 TCM, .22 Magnum, 22 Hornet and the FN 5.7x28mm and is rated for fully automatic fire in .22LR. The USS is machined from billet alloy steels and comes standard with one included ATAS™ insert of your choice. Switching the thread pitch on this world class silencer is as quick and easy as changing out the insert.

While most US made .22s will use the ATAS 1/2×28 insert, other inserts are available for most of the popular import .22s, such as the Walther P22 and G22, M&P22, Colt/Umarex 1911/22s, GSG and Sig 1911/22s, and factory threaded Sig Mosquitos and P226/22s. (The Universal Wrench will work on all of these pistols at the time of this writing.)

The USS is nominally 1” in diameter and 6.4” long and weighs 7 ounces. The tube is finished in matte black and the silencer incorporates a licensed variant of Joe Gaddini’s patented Omega baffle stack.

The USS is suitable for heavy fully-automatic fire in .22 and can be disassembled by the user for cleaning if desired. We recommend taking advantage of our service policy instead, but the choice is yours to make. If you make the choice to clean any silencer, please use proper safety protocols to protect yourself and your personal environment from lead contamination, inhalation and absorption.

Available separately for factory threaded Five Seven pistols are FN Thread Adapters (M10x1/2×28) by Tornado Technologies for $40 each.

    I have had this for a few weeks now and love it. Very well made, very solid construction. And its just silly how quiet this thing is with subsonic ammo… I can actually hear the bullet whistling down range and hitting the squirrel or rabbit or whatever else it is I’m shooting. Awesome product.

    I have several .22LR suppressors as I do a lot of squirrel, raccoon and rabbit hunting with rifle and pistol. Yes, I do eat them, not just for fun! I also dispose of hogs in traps with a .22LR pistol. This is a very solid, well manufactured and easily serviceable Suppressor and very quiet with subsonic ammo. Even with supersonic Remington Thunderbolt ammo which I mostly hunt with, it still is very much hearing safe. Even on a .22LR pistol (Ruger MK IV) this suppressor performs very well with supersonic ammo. I tried this suppressor on my various .22LR hosts and did not notice much of a point of impact shift out to 50yds. Furthermore, I cannot sing enough praises about the company and support from Bowers! Bowers Group, LLC. have made a customer out of me and I will be purchasing more products and services from them. Thanks guys!
