Colt M12 upper November 21, 2018
Reviewer: William Conn from Philadelphia, PA United States  
I have not shot it yet, building rest of plarform. I did not like Colt dragging thier feet. Was not your problem. I have ordered from you guys quite a few times. Great Prices and CS. I am a former infantry Marine with Marksmanship courses in my resume`. If Arms unlimited would like me to do full review I will give feed back. I do have a few questions, what type of Colt 1/9 barrel is it? Match? Accurized? Super Match? etc. Please give me feed back as well
