Airsoft Canada - My M4 Project - From Crap to Awesome!

This is my first project. It sprung from (what many of you might have read) the cheap M4 I recently received thinking it was a JG. This is just the start but I plan on posting updates.

So for right now, this is what I have, the useful parts after I ripped the gun apart and threw away the crap!

Starting from the top (this basically all cost me $16, lol):
- Ejector port fake insides, charging handle
- Delta ring, chamber
- V2 mechbox with decent internals, plastic bushings, front wired
- 300ish round hicap magazine
- motor, grip
- 1100 mAh 8.4V battery
- baggie of parts including ejector port cover, body pins, selector switch, hopup, etc

I've already ordered a bunch of parts to create my franken-M4:
- Complete front end
- M100 spring and bearing spring guide
- regular length tightbore barrel
- metal bushings, shims
- flip up rear sight
- hopup rubber
- Forgot to mention, I already have a G&P M203, which I may or may not use on this gun

I plan on getting
- An M4 body of some sort
- One of huang's CTR stocks

I'll post updates as the gun gets closer to being a real M4!

I got most of my parts! My eHobby order and my metal body:

I got my front end, bitches! I'll have to change out that pesky orange flashhider though.
I tried screwing it on to my upper receiver, and it feels more solid than TokyoSeven's TM M4 RIS.

I got it assembled, except with the crappy stock that came with the other one, and without upgrades. Except for the flip-up sight.
I'm going to see how it fires with the stock mechbox before I install em.
And the body pins are sliding out like butter, I'll have to pick up a set of ones that secure with screws.

My M4 now has a friend to play with. Hehehe.....

Does anyone have battery solutions for Armalites with an M203 attached? I was thinking either battery bag (kinda ew), a battery stock and rewire the gun to the rear (but I want my CTR stock!), or a stick-ish battery and whenever I connect a battery I have to have the stock extended fully (which doesn't matter, when it gets used the stock will probably be fully extended).

================================================== ==

I got all my parts. The only thing is, there's a problem with the mechbox so it's not functional right now. But I can still show you guys pretty pictures!
Also, this thing is pretty solid. The metal body helps to reduce barrel wobble to almost zero, and the CTR stock's locking mechanism solidly locks onto the stock tube.

================================================== ==

Hey all, got the gun working. It has a minor problem with the trigger and selector, but it does fire in semi and full normally. Goes through a pop can, doesn't go through the bottom but ALMOST does. I assume 360-370 FPS as a fairly accurate guess, given that 380-385 goes through the bottom of a can. I weighed the gun with the M203 attached and no shell in, and it's 9 pounds (4 kilos)!
I've got a question for all of ya. Would you buy this gun? I'm not sure I want to sell it, because I built it and it's my "child" now I guess, but I want to ask just for kicks.
