I have a Polymer P80 Zombie Edition lower receiver with jig kit.  This will allow you to buld you own lower receiver.  This kit is no longer avalible from polymer 80 and not even listed on their site.  They are sold out everywhere else.  This is your chance for a cool green receiver to build a Zombie gun or just not be like the other guys at the range.  This can also be your stick it to the man gun as it does not have serial numbers because it is an 80% kit, if thats your thing.  This does include jig, drill bits, and mill bit. No FFL transfer required.
