Try EDC+ They've machined theirs out of solid copper and chemcoated to silver. They're close to the fitment of the stock Surefire 6P's gut. Just not as close as a custom pill I would make but nonetheless, it's all American made. Did I forget to mention? It's a triple drop-in.
Actually it is pretty hard to make sure that everything is made & manufactured in US.
I am sure if the modder uses the regular reflector, pill, driver, thermal compound.. heck, even wires, might be made somewhere else.
My point is that, if those guys trust those parts to mod them & sell to us, I think we can trust their judgment. :thumbsup:

I have multiple Vinh and Nailbender drop ins and they work flawlessly!
