Upgrading my G36

I have a jg g36 and I was thinking about upgrading it.

List of upgrades are as follows -

PDI G36C/P90 6.01 Tight Bore Barrel 247mm
Madbull Gemtech Blackside Barrel Extension (NEW lighter version)
Echo 1 36C Electric AEG Drum Magazine
G&P G36 Sniper Style Folding Buttstock
UTG G36C Side Rails
G&P G36 Carry Handle with 3.5x Scope

Should give it a nice look @ a better spread with the 6.01. It's going to be a sprayer with a B.A. barrel lol. I'm wondering if I should do this or just buy a Mk36. That's the look i'm going for anyways.

go with which ever one is cheaper and/or better

Cool.
