Highnny, I just bought a TSD L96 (same as UTG both are manufactured by Well and rebrand as UTG or TSD) I had the same problem with the hop-up unit, it was not moving or barely moving even when the screw was completely unscrewed. So I took it appart and realized that the pin going through the hop up arm was way too tight in the frame of the hop-up unit and was putting alot of friction, hence why the hop-up arm was not moving or barely.

With a small round file I filed the openings replaced the pin and now the hop-arm works freely like a charm and the hop-up move up and down no problem like it should. I had the cheap plastic ring broken as well. It is only there for keeping the barrel from rotating, so far does not seem to affect anything really, but still I have sent an email to TSD for some spare parts. Should not be expensive (extra hop-up and plastic ring). I am not buying the PDI hop-up, since once fixed the regular hop up does work fine (alot of people seems to don't know how to fix it tough). And I got the Madbull APS2 499mm 6.03 TB with Modify spacers, will see from there after...
