Here are some new photos of additional parts showing just how extensive this modification prototype really is...

Bottom of the Upper Receivers...(conversion is on the top, bottom is 1937 S/42)

Bottom of the Chamber areas (conversion on the right)

Left Side Rear of the Upper Receiver (conversion on top) notice the roughness of the modifications on the sear / sear spring slot.

Right Side Rear of Upper Receiver (conversion on top) Notice the lack of the ejector opening.

All sides comparison of the sear bars (the conversion bar is on the bottom... dramatic and drastic changes here)
