OTs-14 Groza: full disassembly & assembly HD

The OTs-14 Groza (ОЦ-14 "Гроза") is a Russian selective fire bullpup assault rifle chambered for the 7.62×39 round and the 9×39mm subsonic round. It was developed in the 1990s at the TsKIB SOO (Central Design and Research Bureau of Sporting and Hunting Arms) in Tula, Russia. Internally the OTs-14 "Groza" is an exact copy of AKS-74U but in a bullpup configuration and chambered for 9x39 SP-6 subsonic ammunition. The trigger-pistol grip unit could be removed and replaced with an alternative unit integral with 40 mm grenade launcher. In that configuration, a single trigger controls with a separate barrel selector both the 40 mm grenade launcher and the rifle itself. The grenade launcher can use the same grenades used in the GP-25/GP-30. The safety/firing mode selector of AKS-74U pattern is retained. https://en.wikipedia.org/wiki/OTs-14_Groza This video was created using the program World of Guns: Gun Disassembly: http://store.steampowered.com/app/262410/ Also, you can find this application on Google Play, App Store and Amazon.
