Difference between bottom RIS rails in ZeroOne shop

We got this: http://www.zerooneairsoft.com/produc...oducts_id=3479
and this: http://www.zerooneairsoft.com/produc...oducts_id=3481

I have a Classic Army M4 I want to put a bottom rail on (I understand I just bolt the rail to the handguard), and the description of the above products doesn't give me a good idea of their length - after all I want to put a foregrip and a flashlight there.

Anyone has any idea what the dimensions of the two are?
Thanks.

Have you tried to give zeroone a call?

Look at the top of your M4 reciever count the number of raised parts on the rail then compare to the other 2 rails you've linked. Will give you a rough idea of length.
