Base gun for MK12 project.

[ryan1796]

I know this is not the newbie type question but I don't know where to post it.

I'm looking for a base gun for my MK12 project.
First, here are lists that I'm going to use.

1. G&P metal body
2. Madbull JP conversion kit
3. G&P military sniper target grip
4. Magpul PTS MOE

for internal, I haven't decide yet.
I was thinking I get SRC M933 and tuned it but I wasn't sure if those things were going to fit in or not. As I need a gun for just basic foundation, which maker and model would you recommend me? (my main concern is the compatibility and the price)

Actually.....

What I would do here is probably get the metal body and stuff in one of the SystemA complete mechboxes. The "complete mechabox" is the cheapest and similar to a conventional AEG, the "Revolution" is more expensive and from what I understand turns your regular AEG into a "PTW" since it will work similarly to a PTW, then there's the "Energy" mechbox which is supposed to be better than the regular complete mechbox and uses energy from the battery more efficiently or something. After that you have the base of the gun and you just need to piecemeal things like the stock, front end, optics, hand guard, barrel, etc.
