      Kenny –

      That’s what I like to hear, justbgk! That direct mount on the Ruger RXM sounds like a clean fit—no adapters, no fuss. The SCS 320's solar charging and that crisp 2 MOA dot really shine when paired right. Glad it's performing fantastically for you—sounds like you’ve got yourself a rock-solid setup for fast and accurate target acquisition. Ride steady and shoot straight! 🤠🔫💥
