Guys, I have an M4 with (so I was told when I bought it) the factory collapsible stock, and mag extension. I've searched the posts and come up with the fact that the model number is suppose to be stamped on the receiver somewhere. I've looked everywhere on the receiver, and haven't found a model number stamped anywhere.
Just the serial number: Y012518, and number on the barrel: TM15517. No American flags or anything. Just stamped "M4"
and "Benelli-Italy".
I'm about to put it up for sale, and for accuracy's sake, I need to try and figure out the model number before I do.
Thanks Guys.
