ATI 5.56x45mm NATO AR-15 Rifle Parts Kit is rated 4.4444 out of 5 by 27.
Rated 5 out of 5 by from 1-2-3- Rifle First timer at this. Kit was complete. I found a UTube video and things went together real easy. I'm going to try it this weekend. Super price.. quick delivery. Wish there was a kit where I could choose between good, better, best for some of the parts.

Rated 5 out of 5 by from Great value Received my kit and found everything to be in it except the trigger guard. High quality through out and consistent in color. Just wish that they would send a how to put together info for first timers like me. While build another soon.

Rated 5 out of 5 by from Don't Hesitate to order this!! My wife got this for me for Christmas this year to go with my Spikes lower. She gave it to me early so I could go ahead and carry it in my patrol car. Fit and finish is almost perfect! I had to file a very small amount off the inside of the grip to fit to my lower but the result was a tight secure feeling grip. The unit looks like it was made at the same factory as my Mil-Spec lower. At the range it ate everything I threw at it and shot as good as the shooter (me) was capable of. I am very satisfied to have a complete ar-15 the way I want it at a lower cost than with me LE discount through our police supply. I wont be taking long range shots but I know it will work well when/if I need it!

Rated 5 out of 5 by from Excellent quality I am a type 07 home based manufacturer and am very familiar with the AR platforms. This showed up on time and appears to be excellent quality. Have not shot it yet so I can't say anything there. Don't know if it is normal or just a forgotten part but it did not come with a trigger guard. No big deal as I simply ordered a new one. But be prepared to order one fyi

Rated 5 out of 5 by from the AR15 5.56x45MM Rifle parts kit I assembled the parts kit upon the Lower I received form you all after I jigged it out of the 80% and everything went together very nicely and received a firefield scope from you and sighted it in ,it took two shoots and now I'm ready for anything that comes down the path .Like a Deer.

Rated 5 out of 5 by from good basic upper It's all there. The picture is accurate. I put 50 rounds through so far all good. All the pieces, springs, detents etc are there. It costs a bit more than if you found all the parts separate, but it's nice to know it's all there. Shipped on time no problem.

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.
