I've been thinking on buying a 16" Post ban Hbar and having it threaded to fit a FN FAL STG 58 hider.
The STG Hider is threaded close to the front and the rest was to support Rifle grenades.
I know I'll have to open up the internal Dia. of the STG hider for it to fit the .750 Dia of the Ar bbl.
Has anyone already done that?
