It irritates the hell out of me as well.
Not to mention the resale value on all the Chinese crap is pretty much horrible, if it works well enough to sell with a decent conscience.

I mentioned this recently in another thread, but I'm only going to run NF and SWFAs on my guns from here out.

I've only got one Vortex left on a beater AR that's about to be replaced with a SWFA 1-6 or NX8 1-8.

I've got a few sig holosun made red dots I'd like to move too once I find the right Aimpoints to replace them.
