The manual was fairly comprehensive, and had all the safety warnings, instructions, takedown, and explosion diagrams you'd expect. However, there was one thing I noticed.
When comparing the manual next to my WE Hi-Capa 3.8's manual, it was almost the same- done in the same format, with the same pictures (generic safety pictures are reused), and the same texts. The only difference was the gun it was for...
I have a suspicion that WE and HFC are related in some sort of way.
