The instructions were not included in the pack which made the installation process a nightmare to figure out as it was my first time modding any airsoft rifle. I spent way too much time trying to troubleshoot and find how it's meant to be fitted on properly because of it.

If you're not at the beginning with this whole modding stuff the part quality is good albeit could be improved as the button where you need to press in order to fold the stock is quite narrow and the spring tension on it is quite high making it a bit painful when you need to actually press it or you need to fumble around if you're wearing gloves as it's not really all that easily accesible.
