16" Del-Ton upper on a LRB lower with RRA parts kit. Its a carbine length gas system with a quad rail and collapsible stock. Delton is out of stock on all of their items, who knows when they will get more back in. No Optics, however I will provide a 30 rnd mag and rail covers (not brand new, but function flawlessly. The rifle has never been fired, but I built my personal rifle at the same time and it functions perfectly with any ammo (even wolf.) Price is $1500, I would consider a partial to full trade for a 1911, obviously depends on the 1911. Thanks for looking.
