I ordered stripped lower from Specialized Tactical today... with my son's name and birthday as the serial number... and "fun" for the selector if the gun could shoot full auto... I now have to wait 6 weeks for them to make and send to my ffl... waiting sucks but I'm so excited and can't wait to start putting this baby together for my son so I can pass it down to him... (I couldn't think of a cooler personalized thing to pass down to him) it wasn't cheap for a lower $300 but well worth it...
