4 of 5 Looks good out of the box January 14, 2020
Reviewer: D Frank from BIGLERVILLE, PA United States  
Update: Finally got to shoot the rifle. I had some accuracy issues with a lot of random fliers. Discovered the gas block was touching the hand guard. A bit of work with the dremel has gotten me clearance and now I'll make another trip to the range.  

Haven't shot it yet, but it looks good out of the box. It fit right in to my Ruger AR-556 lower with no issues. FDE is slightly lighter than Ruger, but different manufacturers, so almost expected.  Be advised, you should probably order 204 specific mags for this as some 556 mags will not work. The PMAG definitely does not work and will butcher your casings.
Perhaps 204 mags should be offered as an option when purchasing the upper?

4 of 5 20 in 204 ruger upper June 12, 2018
Reviewer: Al from Spring Lake , MI United States  
Thing looks  awesome - shoots 1 inch groups off sandbags at 130 yds. Mounted on my Windham Weaponry lower with just some minor  fitting nice and tight. Only issue is  dust cover  hard to close just needs some work overall sweet  rifle. My new  coyote rifle!

4 of 5 Complete upper January 29, 2018
Reviewer: Anthony Graybill from Ortonville, MI United States  
Great product. Very good fit and finish. Shoots excellent, 1/2 MOA groups at 200 yards. My only complaint is that I ordered it with a muzzle brake thinking that it would be installed, but when it arrived, the barrel isn't threaded for a brake. So, now I have a muzzle brake in a bag awaiting a day when I might actually send the barrel out to be threaded.  I just wish they would have made this more clear, I would not have ordered the brake. Anyway, the way this thing operates, combined with the Anderson complete lower and 3.5 pound trigger; phenomenal. O'yeah, it is a bit heavy with the bull barrel, but I built it for a coyote rig, so I don't plan on hiking miles through the woods with it. Overall, great product, great company.

5 of 5 .204 w/24" Stainless Barrel December 31, 2017
Reviewer: recklesswhisper from California  
Wasn't too sure about this when I saw the reasonable prices but AR15part.com has it Down. Received my .204 AR Upper in about 1 week and it kicks serious... well you know! Build Quality is Top-Notch as is performance! Half inch groupings @ 100yds with good factory ammo.  ^..^~~
