I received and installed my PDI Hop Up, Firefly hard bucking and PDI 6.01 thigt bore PSG-1 650mm AEG inner barrel. The aluminium tube fir the inner barrel is very well made... too much I think, I wonder how much money did I pay for something that is now useless.

Installing the PDI Hop up is a real pain in the ass. The only instructions I found was the video on youtube of the James Bon guy, but it is not very clear. Everything is so small and has to fall on the floor at least once so you can happily turn around on your knees. I still not understand why you have to actualy tape a spring nowhere outside the hop up...

The lenght of the barrel is hidden by the suppressor and there is still place fore a bit more. Now I have difficulty clipping the mag but it's still ok. I only shoot threw my crhono a couple of times, no jam at all for the KSC Perfect 0.2gbbs, and I maxed out at 620 fps, turning +- 600 fps for the shots.

I received and test my third spring (Laylax 170%, 210% and PDI SS 5000)

First of, going from my stock inner barrel of 495mm to a PDI 650mm inner barrel made a lot of fps lost. I went from 656 fps with 0.2g to 610 fps. With .25g bbs, I was shooting +- 575fps with my 210% Laylax spring. After installing the PDI SS 5000 spring, that is the strongest spring I found, I reached 598 fps (0.25g bbs) at 4.0 joules. So a gain of +- 25fps changing to the PDI SS 5000.
