The receiver is scrap; however you can part it out and probably make enough to buy another good shooter carbine if you're lucky. A good barrel is valuable, as are the trigger housing and internals if they have the right markings. Just be sure to find somebody with the proper receiver and barrel wrenches to remove it., or you risk damaging the gas cylinder. You can list and sell everything except the receiver on Gunbroker.com without an FFL. You can scan that site to get an idea of prices. You can also list parts in the WTS column of this site.
