The flash hider itself is compatible with 5.56. It just isn't compatible with the Phantom 5.56mm/.223 suppressors.
This WILL work with the 9mm. I am using it without any modifications on a 9mm AP5 and a YH Wraith XL suppressor, the bore is plenty large enough.
YHM does not list the YHM-4300 LT suppressor as being compatible with the Yankee Hill 431528A Mini QD Flash Hider 5.56 NATO Black Phosphate 1/2"-28.
This is compatible with all Phantom® .30 caliber suppressors however, it will not be compatible with the Phantom® 5.56mm/.223 suppressors.
No, this will not be compatible with 9mm.
This is not compatible with the Original TURBO®. We recommend reaching out to the manufacturer, Yankee Hill for this inquiry. They can be reached here: sales@yhm.net
