Mfg Item #: Adapter STGAU
If you're looking to change the muzzle device on your Steyr AUG or MSAR rifle, you may have trouble finding the muzzle device you want in the stubborn 13x1 Lefthand Metric threading. This adapter solves that for you. The RAT Worx suppressor adapter has internal 13x1 threading and external 1/2x28 threading so that you can thread it in seconds to easily convert your muzzle over to the standard thread pattern. These Adapters are CNC made right here at Rat Worx U.S.A.
