Sorry but I do not have a picture of it, but I found a Colt roll marked Match Target Lightweight. It had a CSL serial number with a pencil barrel, fixed carry handle, collapsible M4 style stock and A2 flash hider. It seems similar to a AR6520, but with a different roll mark.
I wasn't really interested while I was in the LGS, but now that I left my curiosity is getting the best of me. I didn't notice the what size pivot pins it had.
