Thanks for clearing that up. 98Z5V the box says .156.

So google didn't make things clear for me. I just started shooting a gas gun series and I am trying to take parts and use them I currently have to supplement the cost of another rifle. I have a jp roller trigger with .156 small pin screws. I get you can use 5.56 triggers in a 7.62 gun but sometimes they have problems with military style ammo (primers). How true is this? What ar-10 lowers run small pin holes? I am unclear how common this is. Am I foolish to try and make this work?
