Looks Good, Looking Forward to Testing Performance March 13, 2019
Reviewer: Jack Alexander from Troy, OH United States  
It looks absolutely beautiful, and in theory should be pretty accurate and consistent, however yet to test that theory. So far so good.

Colt HBAR January 31, 2019
Reviewer: Michael Devito  
I haven’t shot this upper yet but I must say it is stunning in it’s beauty and perfection. Colt hit it out of the park with this one and it should be perfect with my Black Hils mk 262 ammunition.

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
