I'm looking to build my first AR 15. All I have is the stripped lower, new. Many uppers and kits out there are "Out of Stock", as you all know. Since this is my first AR I'm not looking for the "creme de la creme", but something used, reasonably priced. If you have one with, or without charger and/or bolt, I'm still interested. I have many alerts and email notifications in the works from various distributors and manufacturers, so I'm ready to purchase. Let me know what you have. Thanks!
