I just stumbled upon this outfit today while trying to help a friend with his AK muzzle device choice and I tell you what, the content going on in this series of videos is pretty remarkable. So remarkable that I felt it was worth sharing. There are lots of folks making a living with youtube, but not everyone is providing content this informative. If you're an AK fan and drowning in the sea of muzzle devices, this video series is a must watch. Tons of data, concise and without the BS.
