Prototype 18'' 1 in 6 Twist Green Mountain AR-15 416R Stainless Barrel Test (HD)
This video provides an in-depth test of a prototype 18-inch, 1 in 6 twist AR-15 barrel made from 416R stainless steel by Green Mountain Barrels. The instructor, with clear expertise in firearms testing, evaluates the barrel's performance with various ammunition types, including lighter 55-grain bullets and heavier match loads, at 100 yards. The testing aims to determine if the faster twist rate causes issues with lighter bullets and assesses overall accuracy potential.
