Wilson Combat Shim Kit Mount 1/2X28

The Wilson Combat Shim Kit Mount 1/2x28 is a precision accessory designed to dial in the fit of suppressors and other muzzle devices on .22 caliber firearms with 1/2"x28 threads. If you run a Whisper Suppressor or other Wilson Combat Rapid Thread or Flat Back attachment, shims let you achieve a rock-solid interface without gaps or rocking—critical for both accuracy and suppressor durability. This kit gives you precision-ground shims that take the guesswork out of mounting alignment.

Installation is straightforward: stack the appropriate shims between your muzzle device and the suppressor or attachment body until you've got a snug, gapless fit. That simple step eliminates the kind of micro-movement that can throw off your point of impact or cause premature wear on your threads. Precision grinding means the shims sit flat and won't degrade under repeated attachment and removal.

Whether you're building a dedicated .22 precision rifle, a plinker with a can, or running a suppressed training setup, the Wilson Combat shim kit is a no-cost upgrade that belongs in your tool kit. Stock a few in your range bag and never wrestle with a loose mount again.
