Hello,

I just got my hands on a KAC URX6 and a notched upper from Rooftop. I don't imagine I'll find a KAC barrel so I was just gonna build a temu SR15 and use a standard barrel(probably a Criterion or Geissele...haven't decided yet), I'm just wondering...will this work? Do I need some sort of proprietary barrel?

I'm really hoping this will work with a standard milspec barrel but this is my first rodeo with KAC parts and I know KAC uses a lot of proprietary parts. The upper looks like it would fit a standard milspec barrel extension so I was hoping someone here would know.

Thanks!
