Solid budget rd - OpticsPlanet Exclusive Swampfox Sentinel 1x16mm Ultra Compact Micro Red Dot Sight

I've been running the green shake awake model on my FN 502 for about a year now. Granted it's only on a .22 but it has never lost zero and never failed to wake up when I pick it up. For a budget dot, this one was worth every penny for my use case which is more than I can say for the Crimson Trace it replaced which was best used for target practice.
