Judging by NICS checks, 2017 saw a drop-off from the record set in 2016. But look at that first chart:2017 is still better than any previous year except for 2016. Remington has been tanking for awhile, and in spite of the run-up in sales over 8 years of Obama, it still piddled away it's reputation, quality, product line, experienced workforce, etc.
In contrast, SigARMS [now Sig Sauer] was on the verge of bankruptcy in 2004, but they hired CEO Ron Cohen and he not only turned the company around financially, he vastly expanded their product line in both rifles and pistols, and added new divisions for optics, ammunition, training, etc. He moved nearly all European production to the US to avoid import duties and EU regulations.
