Not as advertised, poor customer service
Buyer Beware. This was advertised with a bayonet lug, it was sent without one. It's a neutered version of the real deal. Finish on the FSB/front sight is also poor but a smaller issue in the big picture. This time they deceptively advertised the bayonet lug, what else are they willing to hide/cheap out on? AU will not take responsibility for their error and refuses to make the issue right in any way even though they are at fault. First/last time doing business here, was ready to buy the 11.5 IAR upper in a few weeks and spend a lot more money over time. Forget it now.

Colt IAR 16" upper
Fantastic offering from Arms Unlimited! This is a heavy duty/ tough built upper that I'm proud to own. If you're a Colt lover, you should get one of these when they come back in stock. A++, Thanks again AU!
