C7A2 mod issues

RCAF · January 21st, 2011, 17:40

I am trying to build a C7A2 rifle but am running into some problems and need some help or ideas on how to get around my problem

I have G&G M16A3 that I am trying to mod. Currently I have the battery assembly in the back stock which is a one piece. http://i.imgur.com/InoKQ.jpg http://i.imgur.com/w7QcW.jpg http://i.imgur.com/bplaz.jpg http://i.imgur.com/IRzNp.jpg

Now my main problem is that Damn wire. It comes out the bottom of the receiver and does not line up properly with the tube for the stock. The other issue is that when the battery is in the chambers of the stock the wires cause collapse of it not possible.

I have seen pics although rare of C7A2 mods and have no clue how they got around this.

Is it possible to rewire the gun and move the battery into the front of barrel assembly grip?

My other question is does anyone know where to find a Metal Canadian Lower receiver?

You could wire it to the front, but it's easier to just wire it properly into the stock.
There's LOTS, and I means thousands of guns that are wired the way you want it to be done.

Firstly, you need to know how to solder, and I mean solder PROPERLY lol
Second, you need deans connectors.
Okay so get rid of that tamiya plug, and replace it with a wire that runs straight to the back so you can actually plug and unplug the battery without having to reach all the way in there.
And you want to use a wire with a large number of strands (that means really flexible wire), and probably silicone coated so it's even more flexible.
Then, when you plug the battery in, spin it so it coils the wire inside the stock tube, then when you move the stock around, it moves the wire back and forth like compressing a spring.

I've done 4 or 5 conversions like this, it's really easy to do.

Hello! Sorry to drop in a year later unannounced lol. ThunderCactus, you say that is is possible to store the battery in the front handguard and I was wondering if there is a specific type of battery that will fit. I've eyeballed the inside of the handguard and I'm not sure even a stick battery will fit :/
So, what battery type will fit in an M16 handguard?
I have a G&G stock M16 handguard

The A2 handguards are roughly the same size as M4 handguards: you should be able to use any M4 type batteries (small, nunchuck/butterfly, stick should fit as well since those handguards are longer).

And if you don't want to run a mini battery and be limited to 1600mah, you can run two sticks in parallel and have a 3200mah battery!

I have two C7A2's (G&P and TM) and a C8 (G&P) and all are now front wired. I can run standard nuncuck batteries in the foregrips of the C7's but with the proper foregrip on my C8 they won fit the foregirp is a tappered style so I need to go lipo. My friend has a converted WE C8 aeg and the nuncucks fit fine in his (the outter barrel on the WE aeg are lot more narrower).

Yeah I think that's my problem. The G&G outer-barrels are MASSIVE, there almost 15mm of space, need 18-20 to fit a stick battery. I guess what I'm trying to ask is if anyone came across this problem before and how they got around it. Im considering sanding down the inside of my handguard :S

Cbielak · November 2nd, 2012, 12:28

Done! I managed to fit a stick type 8.4v battery in the front handguard. I ended up sanding down the inside of the handguard using REALLY rough sandpaper. I also had to shave down the underside of the outer-barrel too (pics included).
To shave down the barrel I started hand sanding but then realized I have a belt sander so that sped up the process a great bit.
In the end it fits by ever so tightly, but that also means its not going anywhere.
Didn't expect this much work

Is there any place that you can get a green elcan cover?

Ares · January 20th, 2013, 01:41

most people paint them, sometimes you can find used but not too often

Rob101 · January 20th, 2013, 14:25

Whats a good paint that flexes?

Ares · January 20th, 2013, 17:34

Pretty much no paint works great, it all will flake after use (you will have to do touch ups). I have heard but have not confirmed myself by Krylon is the best.

Rob101 · January 20th, 2013, 19:23

I tried krylon and it flaked and cracked. I wonder if plasti dip makes od green.
