Izhevsk Mechanical Works is a Russian arms and vehicle manufacturer founded in 1807 by Tsar Alexander I.
Below are some of their firearm promotional videos. I enjoy watching and reading military promotional material which are usually designed to entice the buyer to purchase millions of dollars worth of goods, rather than consumer marketing trying to entice you to try another type of tooth paste.
The first video is about the AK, Dragunov and Bizon firearms. The second is about the Saiga-12 shotguns. These video are also available on the Izhevsk website here.
