Edit: Disregard. I found the only adapter around for it made by Gemtech.
Recently picked up a GSG .22lr AK "Rebel Edition" for my 4 and a half year old son to start practicing on. It has a removable barrel nut with female threads that it goes into. Does anyone know the thread size? I would like to have a custom adapter machined to use one of my suppressors on it.
Any help is appreciated!
