You might be fine with spending $800 on some overpriced supposedly "USA made" RDS for your Glock where most of what you are paying is for the name brand and the price is kept high so that they don't have to discount government purchases.
But the bulk of shooters want something reasonably reliable and useful for the best price they can get.
Bitch and whine and try to shame folks all you want, but all you are doing is pissing folks off. Unless the "USA manufacturers" actually get their heads out of their rear ends and make innovative designs that they can sell for competitive prices, foreign made optics will dominate the lower end of the spectrum.
You might as well go scream at all the folks coming out of Walmart that they are destroying american jobs and funding China with every purchase.
I would also bet that if you stripped apart the "USA made RDS" stuff you might find a lot less of the component parts in it are actually made in the USA than you might expect.
You’ve gone full retard quoting full MSRP like all the other dumb fucks who try to justify buying chinesium.
RMR’s are $450. STFU.
