Great budget red dot - Bushnell RSX-100 Reflex Sight

I placed this red dot on a Taurus TX-22 Competition and had zero problems. I used some blue Loctite on the mounting screws and had no issues with the mount coming loose. This red dot is a budget red dot, not an upper-class expensive model. The Bushnell held zero using 22 rimfire rounds so far up to 400 rounds. Bluish tint is noted looking through the red dot. For a rimfire, this red dot fits the bill. Not sure the longevity on a centerfire caliber.
