Tested the new Rock River Arms barrel build at 100 yards today using my old Leupold Vari-X III 3.5-10x50mm 3/4 Mil Dot purchased in the early 90's when it was all American made! Forgot how accurate the range indications on the adjustable objective are. It means what it says! The barrel is a Rock River Arms 20" Chrome HBAR, Wylde chambered but with a 1:9 twist instead of the usual 1:8 for a Wylde. I now consider this barrel sub MOA!
