Pic Request: Inside an Ares M4 Upper Receiver
 

Like the title says, I'm looking for a picture of the inside of an Ares M4 upper receiver, close to the front, without the hopup. I have a Deep Fire PTW style barrel and hopup I'd love to use but it won't fit in most common metal receivers, but I did hear it drops right in to an Ares. So if anyone has experience with this barrel set, or can provide a picture of the upper, that would be great.
Thanks in advance.
