Handguard Help

[Space Bot]

So I have a stock TM M4 (only upgrade so far is some torque up gears) right now, and I've fallen in love with the HK416 handguard.
Like the one listed here on Ebairsoft
http://www.ebairsoft.com/hk416-aluminium-p-1152.html

What I'm wondering, is it possible to attach it to my receiver once I get all the necessary screws and barrel nut (if that's what it's called)? OR would I have to end up buying a completely different receiver for it to work?

I know that the one listed on ebs comes with no screws or anything, and (I don't know if it's true or if it's that one guy saying it) that you need a different kind of delta ring for it to attach to the barrel nut (Still new when it comes to airsoft in general so please correct me if I'm wrong, have to learn some how)

Any and all help is greatly appreciated.

You do need a different delta ring thing. And the rails will be too high for your body. But if u need the HK416 rail for the receiver pm me i have lots.
