Does anyone have pictures of before and after a barrel chop and pinning to keep the barrel above the 16" regulation?

Also with that said does anyone know the amount that can be cut from a 16S while maintaining the stock muzzle break?

Maybe Jarod from PMM can chime in with the amount removed while utilizing the stock muzzle break.

Thanks,
Also I've had my SCAR way to long (2+ years) and never posted here, sorry I'll post something eventually.
