I was recently thinking about building a new AR. I discovered 6mm ARC. I've been interested in 6mm for a long time but there were so many different ones and ammo was not really available. Now we have 6mm ARC and you can buy it online. It seems like a great round. Great for AR also. Kind of like 308 performance in a smaller package and reaches 1000 yards. I think I like it. Is this round a hit or a miss?
