The viewers have spoken and today we're comparing an AR-15 16 inch barrel vs an AR-15 20 inch barrel! I added a PSA 20 inch 5.56 upper with free floating barrel to my SBR lower and I want to see if the 20 inch barrel really is the king of 5.56 when it comes to speed and destruction. I really like the way that the 20 inch AR-15 feels to shoot, from the hold of the gun to the nearly non existent recoil. We tested the 16 and 20 inch 5.56 AR-15s again wood, concrete, and steel and they came out close!
