A complete gallery is available here at Brickshelf. Here a couple pics from the LDD, which was originally used to create this.
This is the first thing I'm posting here, though by no means is it the first LEGO® model I've made. This one comes with quad Picatinny rails n the handguard and an uninterrupted rail on the upper receiver. The gun itself is not one solid part. Rather, it is a modular rifle that comes as an upper/lower receiver, detachable stock, and removable magazine. There are optics and sights that can be attached to the rails as well. It's about 3 feet long, plus or minus a few inches depending on what length you set the barrel at.
The charging handle, unfortunately, cannot be pulled. I do know how to design it such that it is possible, but I do not have the pieces available for that.
If you would like instructions for the model, download here. You will need to have the LEGO® Digital Designer program to open these instructions, and this particular model uses over 1200 pieces, just to let you know.
