Type 81 Full Monty disassembly & field stripping for cleaning. Folder, Fixed & Clubfoot (LMG) Stocks

This is an updated version of the Full Monty which I included all three versions- Folder, Fixed & Clubfoot stocks, the old video was deleted. The receivers are not interchangeable, the folder is completely different than the other two. The fixed is similar to the LMG except for the locations of the pin holes that secure the stocks. When removing the stocks, secure the rifle vertically by its front trunnion or gas block (protect the finishing) and never by the receiver. Tap the front of the stock gently using a mallet and a rod. Other disassembles: Furniture. Bolt. Fire control group (FCG). Buttstocks. Removing Grenade Launcher. Optic Mounts: Quad rail rifle- Sigmacocanada. Gnutzguy's No drill side mount- 3 pins.
