Most Helpful Negative Review DEFECTIVE, DO NOT BUY!
I was really excited for this product when I saw it on back order. I went on to their website and saw they had a nice laser logo on the back side of it with DH. But when I received it, it had a crappier logo on the side of the charging handle area. To add on to that, when I installing the door port...

Very Good Billet Upper

by JWE, from WV, United States Written on February 1, 2022
I bought this for a new build to give it a shot. Its a great upper, with as noted some issues with the port door opening. I had to change to a port door with a larger tab mechanism because the first one I put on, mil spec, would not stay closed. Beyond that, I like everything about this upper receiver and have several hundred rounds through it. Very good billet upper for the price of many forged uppers.
Pros:
  • Price
  • lifetime warranty
  • Appears to be well made.
  • Good looking and works great
Cons:
  • Port Door Specs
Would recommend: Yes

Very Good Billet Receiver

by Roger, Verified Owner from TX, United States Written on April 30, 2021
I wanted a billet receiver that would match with my JBO Spartan Billet lower. This upper had a perfect fit to my lower, no slop at all. As far as second cool, it looks awesome. I used SI dust cover and forward assist, no issues installing them.
Would recommend: Yes

Out of spec

by Edward, from CA, United States Written on January 4, 2021
I’d recommend getting some other upper that doesn’t have issues. The port door is completely out of spec. You literally have to press against it really hard to close. I tried it with a strike industries billet port door purposely for this billet upper - did not work. But I tried it on 2 of my other uppers with no issues. Plus, there’s no back logo as the picture stated. I really wanted to love this thing but now I have to spend more to get what I want.
Pros:
  • None
Cons:
  • Spec issues
Best Used for:
  • Without a port door
Would recommend: No

Nicely built, but with compatibility issues

by Jeff, Verified Owner from CA, United States Written on November 27, 2020
The machining and design looks nice, but the area forward of the ejection port and behind the barrel nut are not Mil-Spec dimensions.

As such, if you have a handguard with anti-rotation tabs or wraparound design, it may not fit. Some may see this as a "feature" because it's thicker where it supports the barrel extension, but compatibility with Mil-Spec dimensions is more important, I'd think.
Pros:
  • Solidly built
  • Nice machining
Cons:
  • Compatibility issues
Would recommend: Yes

great product

by robert, from OR, United States Written on July 10, 2019
I've been looking for a billet upper receiver that was the right price range and not overly expensive. I came across dark hour defense upper receiver and the price was right!!! the fit and finish was spot on, it had extended feed ramps which is a plus. But over all if your in the market check out dark hour defense products.
