A: A red dot is a type of reflex sight. “Reflex” refers to the sight style — open or tube — while “red dot” is the aiming system. All red dots here are reflex-type optics.

A: Most models include a mount for Picatinny or Weaver rails. Always check the product details to confirm compatibility with your firearm.
Q: Will cheap red dots hold zero?
A: When mounted correctly, many will hold zero under moderate use. They're great for range practice, plinking, or backup optics — but not ideal for harsh-duty environments.
