m4 project

Hello!
I am very interested in buying an m4 body and buying the small parts to make it function. I already have a full body set in mind (the G&P Magpul Type Metal Body for Marui M4) that includes a New Dust Cover Set, New Bolt Cover, Metal Hop-Up Set, Receiver Pin Set and a Forward Assist Knob.
What other parts do I need for it to fully work that way I can just insert my GB into it and have it working.

So far i know i need:
- Selector switch (do i need two, one for each side?)
- Mag catch
- Bolt catch (Now i found the normal paddle shaped one and an ICS one with a wire cover. What is that?)
- Is there a bolt catch spring?
- Charging handle
- Charging handle spring

That's all i got so far.
My goal is to have it in fully functioning mechanical order before placing in the GB.

Am I missing anything else?

Thanks! All help and advice is greatly appreciated!

You can always cut the barrel down to the length you want.Its not hard to do,admittedly recrowning will take longer because the one you want is stainless.

I actually thought about it but was hesitant because it is steel. Would you recommend I use a dremmel? Also I am not too familiar with the barrel crown at the end. Does it need to be any specific angle? What tool should I use to re-crown it after I cut?
Thanks!

I like to use a break line tubing cutter when cutting down barrels,but a dremel will work.Just get yourself a metal cutting disc and have at it.Just make sure you cut it straight.For crowning,use a hard cone shaped grinding wheel on your dremel at low speed.Applying oil while grinding the crown will save your stone,and keep you from burning up the barrel.
For ease buy a Full metal body with all the trimmings. Then buy a barrel, RIS stock, maybe buffer tube, barrel hop up unit and gearbox.

And don't get a fagpul body, Get a KA or vltor or something or other.

What really? Why not magpul? I've been eyeing that body for a long time now for my new project! It looks fabulous! What's your reasoning?

Is that it!?!?! Haha! Ok well in that case I am still going to get it.

I admit to haveing magpuls on my mag and an AFG but other than that, No. They are over-rated over-priced pieces of crap with a brand written all over them.

I see where you're coming from and to an extent I do agree but this is an exception as I am trying to stick to a specific design theme and the Magpul body happens to fit it exactly to my plan.
