I stick with Vortex, or Leupold, generally... for red dots, 100%. They both are US companies (I'm sure their manf facilities and what not are in chiina, whatever) with solid, long-term reputations for honoring their lifetime warranties even on electronics.
For $150 or so you can get a vortex Amazon product
I have 2 of them and they are durable. I know a bunch of people who run them and I'd seriously recommend spending the extra money on one vs a pinty/etc.
I put a rails top cover on an Uzi model B. But since the top cover isn’t really locked in place accuracy will never be great. So something like that would be just fine as long as it doesn’t break.
I’ve had other stuff where it would be fine to have a little RDS to throw on it, but not the end of the world if it broke. Same thing. Not worth $150 to add, but why not throw $30 at it. If it’s something I plan to use for self defense or hunting I’d probably spend more.
I have noticed the dot tends to be less crisp on the cheaper models.
Might pick one up for a HandiRifle. Been trying to decide what I want on it.
I’ve got a PA micro that’s held up pretty well for several years also.
