Hushpower AR

Hi All,

Was given a Hushpower AR supressor with standard AR thread. (It says HUSHPOWER AR on the lip at the end) Can anyone tell me if the Hushpower AR is in fact the right size for the .223/556 rounds and not 300 calibre? Got mixed results when searching online If I was to check using digital calipers what should the size be for the exit hole?

Cheers,

30 cal AR barrel will normally have a 5/8-24 muzzle thread.
