Good barrel for a good price - Diamondback Barrels .300 BLK AR-15 Nitride Barrel

This is actually the second barrel I've owned from Diamondback. Their barrels are as good of quality as anything else I've seen. I don't know if the finish will hold up after a month of combined jungle and desert at-the-same-time warfare conditions. If you freeze it, it may not shoot, but it also may shoot. I don't know if they will do an 1/8 at 4,000 yards. I can't answer if it will do 94 mag dumps in 103 seconds while suppressed on full auto. I also don't really care. They install and headspace properly, the measurements are correct and they are accurate past 100 yards, so I'm happy.
