that is a cool video. In the last part there is a particular angle of view on the rifle when the video is in slow motion where you can see the significant flexing of the barrel from the muzzle into the handguard area ahead of where the oprod guide would be on the barrel. Pretty crazy how noodley the standard profile barrels are during the recoil impulse and yet a great many of those standard barrels shoot and group really well. This is the main reason for tweaking all the parts for optimal harmonics.
