Classic Firearms Grendel Barrel Review.

[grayfox]

The chamber is difficult to inspect. Without casting or a more expensive bore scope you would never know what you have.
I have added casting metal to my cart. I will take my chances with "chemicals known to the state of California to be hazardous to my health."

Understand Bj... I respect your choices.
But fwiw I didn't care what Calif thought about it, I know those metals from my nuclear days.
