Excellent fit on my Ruger lower. Now its time to test the rifle and I'm sure I will be happy with this purchase. Highly recommended dealer with excellent customer service and following up with my order.

Great upper shot well at three hundred meters after zero. The CORE is a Veteran run company, and being a veteran myself I have to say this is 200 times better than the M4 I hade in the military. The upper does not rattle and dose not care what you shoot through is. I shot steel and brass cased amow, about 150 rounds in all and I didn't have one malfunction braking it in. Would buy again if I need another AR. Is a good buy.

Ordered this upper for a build I was doing. I was pleasantly surprised when it arrived the next day considering that no special shipping was requested. The new upper fit my Bushmaster lower perfectly and is nice and tight. So far gun operates flawlessly. Finish on upper is good and no flaws that I could find. I highly recommend this upper for anyone that want's a 1-7 chromed upper in 16 in. 556 cal.
