Do these "phosphate coated" barrels have any kind of lined barrel treatment such as chrome lining or nitride? From the description it would appear the outside is phosphate coated while in the inside is bare steel.

Where is the blemish on the upper kit????
Jason T on May 24, 2018
BEST ANSWER: The only thing obvious was the crush washer wasn't centered. Everything else looked fine on the one I got.
Is this rifle kit 16 inch 556 nato 1/7 phosphate classic compatible with the poly80 lower?
Scott m on Jun 4, 2018
BEST ANSWER: It certainly should work just fine. As with any 80% lower, it has to be finished out properly. Be sure the jig is exactly where it belongs before you start drilling.
The OAL listed is 24.5 inches. Do these completed builds then need to be registered as SBRs?
Michael H on Aug 5, 2018
BEST ANSWER: Overall length as fully assembled and complete should not be less than 26 inches overall.

Wow - really nice
I just received this kit so I haven't had a chance to build it out and fully test its function, so I'll have to update this review once I have. But I can say that while unpacking it I immediately looked it over for general fit and build quality (things like the gas key, movement of the bolt carrier, gas tube and alignment of the muzzle device, etc, etc...) I have to say I'm impressed and I actually forgot that I had ordered a "blem" model while I was inspecting it. I'm actually not sure what part of it is suppossedly blemished, but I'm guessing it's from some small cosmetic marks here and there. Really no big deal and frankly they are the kind of character marks that I'd expect to get on it just from taking it to the range a few times. I wouldn't hesitate to buy another "blem" model in the future. Great deal!

No problems with any of the parts. Rifle functioned perfectly after assembly. At this price it is hard to beat.

Nice rifle kit went together really well the only blem was on the top inside of the upper where the coating wasn't even which won't hurt a thing great rifle kit for the money put 50 rounds through it and it never missed a beat

First Build
This is my 1st AR and my 1st build. I enjoyed the experience of building my own gun. It seems to be good quality. I am not sure where the blems are...but who cares. I have not fired it yet. I can’t wait to go to the range. My only complaint is that it did not come with a rear sight and as this is my first gun of this type, I do not know exactly what I need to match up to front.
