Hey guys, thanks for letting me on the forum and I need some help. I'm new to these but have worked at a gunshop for a little while now. A pre-ban Cobray M11/9 came into the shop and I have the chance to buy it. I have about 40 pictures I would like to upload here for advise on if it is no good. The welds seem ok but it looks like something is not right. The top charging knob is leaving peening marks on the upper. Inside the lower receiver there seems to be an issue also related to this. It looks like the bolt is slamming into it. I don't have much time to figure it out because my boss wants to sell it asap. I can't figure out how to down size my pictures. I know you guys would be able to steer me in the right direction and I'm frustrated that the pictures won't upload. I don't mind getting the upper replaced but want to know if the lower is still ok. I always loved the look not so much the function of these since late 80's and mid 90's movies. Please advise. I really appreciate it. Thanks.
