ATI 5.56x45mm NATO AR-15 Rifle Parts Kit is rated 4.2857 out of 5 by 21.
Rated 5 out of 5 by from This rifle parts kit was very easy to install. It shot well when I tried it out a few days after installation. Only thing I did was run a patch through the barrel before I shot it. Biggest problem i found was that there were instructions with the kit. A quick search on the internet was all it took to find step by step instruction.

Rated 5 out of 5 by from Great kit! Haven't had it to the range yet, but fit and finish are on par with the very best. With very minor fitting, it locked up tighter to a new milspec lower than any of my Colts. Kit was very complete (except for trigger guard, as per the ad), well packaged, and easy to assemble.

Rated 5 out of 5 by from All parts fit well on my lower receiver.... no apparent problems so far. Have not had opportunity to shoot it yet, but hope to this next weekend; however I did cycle a few rounds through the completed rifle, and they all fed and ejected perfectly. The upper assembly seems well fitted overall, and the finish is superb.

Rated 4 out of 5 by from It was a good product for the price. although I think it could be packaged a little better to a low for some rough shipping. My only issue was I had to file a little of the radius of the upper by the rear pin hole tab, the barrel plug was broke from some rough shipping and the trigger disconnect spring was missing which I'm sure the SG will take care of. Thanks again SG

Rated 4 out of 5 by from I ordered two of these kits. One had the wrong spring installed on the dust cover, so I used the upper out of the other kit until the faulty spring can be replaced. I have not checked the lowers parts in the second kit but they were all there in the first one. Made for an inexpesive build so far.
