Thanks, Mr Teatameh, that's nice of you! The scope is a Vector Optics Raptor 4-14 X 50 and it is big indeed!
It really looks bigger than it is because it has the "sunshader" or whatever its name is, attached to prevent the sunlight from spoiling your aim.
As for internals, it only has a JB Unicorn 6.01 precision barrel and I changed the original Tamiya connector for a Dean one, as I only use LIPOs. I have only used it once and I still new to get used to the DMR role but it is really refreshing and fun. I love this AEG.
