Just received mine today. Took exactly a month to get here, as I opted to get mine pre assembled.
It looks fantastic, and feels tight. I am used to having beat up old rifles from the Marine Corps, so it is a nice change of pace to have things that fit together so nicely. Everything appears to be in spec, and just feels solid. The sights and the hand stop are great attachments to come directly with the build.
The only “complaints” I have that are not that bad in their own respects are:
1- I bought the ambi charging handle; the right side works but is slightly gritty, however I’m sure this will ease up with use (as all things do)
2- The dust cover was faintly scratched, as in multiple scratches but only enough to see, not feel. This is a non issue though because it is a rifle, not a car. It will get beat up so I figure this just kickstarted the process
Overall love this upper, I would 100% recommend this to anyone who asks, and look forward to having this for years to come.

Love this kit. Its my first build so putting together took a little while. All the parts were there so no problems at all. Parts were all quality parts! Ordered 2/22 shipped 2/27 received 3/5. They answered all my emails and any questions i had.

I Love this gun shots good

Just finished building this kit all and all it's nice only issue is I thought because it was 10.5 inch barrel it would have a regular gas tube but it comes with a pistol still great gun for the value
