$100 shipped and fee'd through hopup! AAP-01 CTM AP7 kit This kit is pre-modified to prevent the rear upper to break/blow out from a design flaw and use the rear sight to hold the bolt as originally designed. Disclaimer: The top rail in the front has left over glue from previous owner, if this is a concern options can be discussed to remove the glue to the best of my abilities. No issues or flaws other than what is mentioned😁
