A-15 M 6mm ARC Complete Upper

Very happy with it ...worth the wait!

Well built, feels good, shoots excellent, no complaints.

Update from Nov of 2021, 3 Hornady factory loads & 1 handled (87 gr Hornady Hp Bt) Hornady Black 0.75" group, other 3 all 1/2" to 5/8", point of impact all within 3/4"(no resighting) and I'm old, almost 70, a little shakey, best $ I ever spent

This upper is very high quality and an absolute shooter! It shoots all the Hornady offerings well but seems to like the ELDX the best. The folks at Atheris were very responsive to my inquiries and a pleasure to work with.

I’m super excited that it is all I hoped for and a bit more. If anyone is wondering if they make good barrels without a doubt they do, you won’t be disappointed.

Received my upper it was worth the wait. With factory Hornady 108 grain it's shooting sub MOA at 100 yards 5 out of five all touching one another. I'd definitely buy again. Thanks

First 5 shots on new upper sun moa. Next 40 were ringing 3” gongs at 300. Super accurate. Great product.

Everything good. Very accurate

I just received my upper and couldn't be happier. It fit perfectly with a milspec lower I had. The quality and craftsmanship are top notch. So glad I went with Atheris. It was absolutely worth the wait! I have no doubt it will meet 1 moa guarantee. I cannot wait to get it to the range. They were great keeping me updated and replying to emails. Thanks Kim and Zach!

It took awhile to receive my upper, do to the current situation of our world right now is to be expected. The fit and finish of it is excellent.

Great upper. Took to range. Great groups, sub MOA.

Looks good out the box and fits a Anderson lower good. I added a Accuracy wedge to the lower and I did a 10 round test with Hornady Match the last 4 rounds was under .5 Moa @ 100yds.
