 All right, Marines and sailors, we've got an excellent question for you today. Corporal Affleck, who's an infantryman from 1.6 and I, we're talking about short-barrel rifle versus long-barrel rifle, which is more effective, which is more accurate. Today we're going to test that. So we're going to have him suit a precision rifle and establish a group as a baseline to measure the short-barrel rifle and the longer-barrel rifle. First, a 14.5-inch M4A1 Sotmod RIS-2 with a suppressor. And then we're going to compare that against the Daniel Defense Mark 18 10.3-inch barrel with admittedly a much larger scope than it needs. But I want him to be able to aim precisely so we can establish a really good group. Now, you'll notice from the results, he suffered no accuracy penalty due to having a shorter barrel on the weapon. That's not the way it works. Accuracy of the ammunition, accuracy of the shooter, condition of the weapon, all of those factors play into whether the rifle shoots better or not. It's not the barrel length. Now, you will suffer, as you saw in an earlier video, a velocity loss but not an accuracy penalty. Semper Fi Marines.
