Wilson Combat Shim Kit Features The Wilson Combat Shim Kit is purpose-built for the Whisper Suppressor interface specifically engineered around 1/2x28 thread pitch muzzle threads common on .22 caliber rifles and pistols. Precision ground shims ensure a perfect fit between the Rapid Thread or Flat Back attachment and the host firearm s muzzle which helps maintain proper suppressor alignment and performance. Replacing worn or damaged shims with this kit restores the tight consistent fit that keeps the suppressor mount functioning as designed. Because the shims are precision ground rather than stamped they fit more consistently than generic replacement options. Installation is fast and straightforward requiring no special tools beyond what is already used to service the Rapid Thread or Flat Back attachment. This makes the Shim Kit a practical accessory to keep on hand for routine maintenance rather than a specialty tool reserved for gunsmiths. Finished in silver to match typical suppressor mount hardware the kit integrates cleanly with the existing attachment. Compatible specifically with Wilson Combat Rapid Thread and Flat Back attachments the Wilson Combat Shim Kit is an affordable necessary maintenance part for sale at GrabAGun.
