In mine mod the hop up arm - adjustment is 90° degrees and it can hope even 0,40bbs without any problem. Charging handle and spring isn't functional but if I have to choose between that and some great shoots, I go with the second.. The slap is lost...

Same.. I measure and drill a hole and after I used some windscreen glue to stabilize two nuts and a screw going directly in homemade hop up arm... A lot of hours to customize but worth it...

P90Greetings from Greece! Mp5 s hop up unit is shit.. I also have a jg sd6 and i m done the TDC mod and also rhop flat hop. I can hit targets 50cmX50cm at 65-70m with 0,3 bbs on a m110 spring and stock barrel.i can stand against higher value replicas easily... Ask me if you want to know what I'm done
