Used on zastava m70 - Griffin Armament Suppressor Alignment Check Rod

I have a Zastava M70 Ak and I’ve heard they are notorious for having issues when going to suppress. I have a YHM mid length muzzle brake that bottoms out on the barrel. No crush washer or spacers needed to time. It bottoms out before it touches the sight post. Which you don’t want by the way. The sight post is basically pressed on and its not okay to bottom a muzzle brake on the sight post. But I used the alignment rod and my barrel was slightly off with my YHM RS9 attached. But it cleared and is good to go. I would recommend using these rods.
