I've really enjoyed Larry Vicker's videos on Russian small arms. The AN-94 has always had some mystery about it, and his first time behind the trigger of one was less than impressive, but the most recent high speed video demonstrating the 1800rpm two-round burst setting was pretty cool.
But more interesting to me is the fact that while the AN-94 seems destined for obscurity, back in 1994 it triumphed over the AEK-971 in the 'Project Abakan' trials to select a successor to the AK-74. Yet the AN-94 is out of production, but it appears the AEK-971 is lingering on with the improved A-545 (which was recently selected along with the AK-12 as a candidate to replace the AK-74...though that decision has seemingly been superseded by an AK74 modernization effort). The A-545 and AEK-971 are descendants of an even earlier effort to supplant the Kalashnikov known as the AL-7, which introduced a novel balanced recoil system. Deemed too expensive at the time, this innovation appears in the A-545, AEK-971 and the recently introduced AK-107/108. What's old is new again I guess...and Larry got to play with some of these too...

He also has videos on the AK-12, and AK-400. Great use of the high speed video...interesting stuff!
