Riddle, Spike, Crosshair, Warden and Montefrio are not made in the US.
Or at least they aren't labeled as being made stateside. I know a lot of wires have some printing under the earsock nowadays, but usually just the part number and not the Made in USA tag. Doesn;t mean they aren;t though, there is just not a lot of room to print it there. It's the high end metals that are made in Nevada. The X-Metal and Mag frames. Other Wires may be made stateside. I know a few of the Rx are made in China or Japan according to the boxes.
