M4 Building Questions

Hi guys, I have a few questions.
One, do you need a delta ring to connect the front barrel set, to the upper and lower receiver?
Two, How do I connect the Charging handle and the selector switch to a M4?
I need help guys, I'm making a M4, and I'm a bit confused.
Please ANSWER FAST
THANKS

The delta ring is what connects the barrel to the upper receiver, The pins are what hold the upper and lower to eachother.
What are you connecting the charging handle too?
Its always different but usually you need to pop out the little tab on the opposite side of the body where an amdidextris selector switch would be and just unscrew it, the gearbox needs to be out though.

Okay, so I do not need a gearbox to connect the charging handle?
Do you guys know where I can buy a complete Charging handle set,
also where do i buy pins for the upper and lower receiver.
I was thinking would these pins work?
Body Pins for Upper and Lower Receiver

Those pins are the correct ones,

Unless you are working on a PTW, the Charging Handle is mainly for optic and sliding the Bolt Carrier Plate back to expose the Hop-Up adjustment Wheel or Gears. The Charging Handle is attached to a spring which is attached to the inside of the upper receiver.

So the charging handle does not need the gearbox to install?
If I install the charging handle, how would I make the dustcover to fall down when I pull the charging handle?

also would this body be good?

thanks

i i saw that people acually posted stuff on here and i was wanting adice herehttp://www.airsoftallies.com/ask-a-pro-f24/m4-boneyard-stuff-t2504.htm

On the charging handle there is a little part of it that sticks out. This hits the little button on the dust cover that causes it to flip down. Just make sure you put the spring on the dust cover correctly. It might take a little while to get it right.

you could get this http://www.airsoftpost.com/king-arms-reinforced-accessory-series-type-p-27659.html and have some spare parts since it's cheaper to buy this insted of all the charging handle stuff and the dust cover here http://www.airsoftpost.com/m4m16-series-dust-cover-p-27312.html and if you haave any more questions on m4 externals come to me i spend alot of time looking for them

okay thanks guys
but what about that external body i was talking about
metallica you think that one is worth it?
The one I linked earlier?

well that is abs plastic do you not want a metal one but ya that is fine if you want abs

well full metal is like 100 dollars right?
i'm just building a simple gun at the moment

ya it's fine but correction is $100 with the needed hopup the body it'self and i would suggest getting a metal hop up so you can get the metal body later http://www.airsoftpost.com/full-metal-system-m16m4-series-p-25930.html

do you guys recommend this gearbox to be put in the plastic upper and lower receiver right there?

wrong if you want a full metal receiver they go for ~ $50 alone.

RIS systems/ metal handguards anywhere from 50 - 100$ depending on quality.

Personally I recommend buying a bone-yard-ed high-quality M4 like a KWA/ CA/ ICS which still has the full metal body then repairing/upgrading it to working condition.

I can't find any boneyard with a ful metal body.
you know where I can find one?

It doesn't necessarily have to be a boneyard gun. You can probably find something used and working for about the same price as the gun being broken.

would this be good? http://www.airsoftgi.com/product_info.php?cPath=275&products_id=495

No because it is a SR 25 not a M4 FYI.

Just look for a used gun at your field's or on craigslist. Good luck. It will be a chunk of change but most of the stuff your going to need to buy will already be included.

okay i guess i'll try something else thanks
but wouldn't it be better to build from scratch?

No building from scratch will run you into the same amount of money. Then there are concerns with specific upgrade parts not being compatible with upgraded shells ect.

Better to upgrade from stock then scratch.

true
so i should get a boneyard huh
alright thanks lonewolf
i'll keep posting on this topic if i have any more questions

Actually that gun you linked to for a body was not a sr-25 as lonewolf said. It is a M-16A4 which would work perfectly.
