M4A1 suggestions needed

thepantsdragon

I have been working on an M4A1 with some minor modification to the original reference just wanted to see what you guys think of it 

The area in red is where i am currently working on, i cannot seem to get the reciever of the gun to look right, any suggestions?

Reference:

What do you seem to be stuck on specifically with the upper rear there? I grabbed a couple of reference images for you if they help.



If you're doing this as a high-poly, I'd suggest doing the receiver in two parts like it is irl, also you need to shear off the rail sections (look at the first picture).
