I looking at buying one of the DSAs uppers for my DPMS lower. Which one (Park or Std) would match the finish on my lower best?
I believe they are referring to the barrel finishing, not the upper receiver. You can tell because they list their stripped upper receiver as being hardcoat anodized, but on their complete uppers, they list parkerized or nitride treated barrels.
Also, DSA does not chrome line the bore and chamber. That’s why they’re so cheap!
