SRC MG36 upgrades
 

As the title says I will be getting my hands on an SRC MG36 later today. I'm just wondering about what I should do to upgrade it from stock. Should I go the high speed/high rof route or should I aim more towards just replacing the stock parts with higher quality parts and keep it at the same specs? I know that its gonna get a 6.03 tbb for sure and maybe upraded wiring as I do in all my guns.

I've never had any experience with SRC so I don't know what their internal quality is like to begin with
