A15-M Billet 6.8 SPC II Complete Upper Receiver

5 stars! Great build quality and superb customer service. This upper is shooting sub MOA with 90 gr Barnes TTSX loads (.78"). I will definitely be ordering my next upper from Atheris.

This is the second upper I have purchased from Atheris and have no doubt it will be as advertised, The 6.5 Grendel that I bought is great to shoot, looking forward to shooting the 6.8 SPC.

Very well made with quality components. Upper is very tight and is shooting.75 Mia with quality ammo. Can’t go wrong with this upper. Thanks for a very well made upper.

Have to say that the quality of this upper is top notch. I took it to the ranch groupings were tight no loose components on the upper. Amazing build quality I had issues with the post office damaging the upper and the owner zach curtis went above and beyond to get me handled and taken care of if your on the fence I definitely recommend going with atheris
