Hello and welcome back to another video! In this video I will be upgrading the Cyma MP5K (CM041K) with parts most people can find anywhere, and they are usually cheap. This is not meant to be a guide, but if this video helped you in anyway be sure to leave a like and subscribe to the channel for more videos like this in the future. #airsoftgun #airsoft #diy
