First Grendel....

That looks great.

What gas block did you use?

Did you measure your port?

The Satern 18" fluted cut rifled barrel I had was drilled with a .094" port, which needed a PRI adjustable gas block to choke it so it would run reliably.

With the adjustment screw almost completely closing the port off and with a rifle buffer and spring in a rifle RET, it still ran pretty hard.
