Shortest AR-15 barrel ever is smaller than some snub-nosed revolvers

A snub nose revolver has a barrel length of 3″ or less, so does that make this AR-15 with a 2″ barrel a snub nose rifle?

This SBR AR-15 has been cut down so far that the gas block actually extends PAST the barrel.

The barrel is so short, the ammunition it fires is longer by more than 1/4″.

You can see the tips of the bullets extending past the barrel in the video.

Surprisingly there is virtually no flash since a great deal of propellant is essentially wasted and can be seen as black smoke leaving the rifle.
