.458 Socom Barrel and BCG
This is the second .458 socom upper I have built. This was my first purchase from Atheris. This barrel is far superior when comparing the craftsmanship to my other barrel. I had accuracy and feed issues with my other upper. Those have been corrected with this new barrel and properly headspaced bolt. With a sub minute guarantee from Artheris I’m can’t wait to take this thumper to the range.
