While I would like to take this into consideration in all my firearms and firearms-related purchases but sometimes I'm just not willing to sacrifice quality to buy US made.
Example my Steiner M5Xi and my S&B PMii, at the time and possibly currently there are no US comparisons with the exception of USO which has had complaints about QC in the recent years or the Mark 8 which wasn't out at the time of purchase of both scopes.
Most everything else I buy is US made simply by default but then I still think distinctions have to be made. Is my Glock or Sig US made? On the slide of my Glock(s) it says "Austria" but on the frame it says "Smyrna, GA". So is this considered Austrian made or US made? I'm guessing it's like Toyotas in the US. The Tundra is the most American made truck in America but it's owned by a Japanese company. I think there's a lot of grey area in the phrase US made.
