A useful tool for LCT and GHK Airsoft AK owners is the C-32 Utility Buttstock Removal Tool. The C-32 is mainly made of Nylon Fibre that has certain slots for you to place the appropriated model and be able to remove the buttstock quickly. Once you have removed the buttstock then you can update the stock with any of the optional buttstock options from LCT Airsoft. Just check compatibility.
