Dan and I hit the Ruger booth at the NRA show this year to check out their Mark IV 22/45 Lite Optics-Ready semi-auto pistol and the new ReadyDot micro red dot.
This new optic uses a huge coil of fiber optic to gather light and produce a 15 MOA dot on the compact viewing window. Clearly it auto-adjusts for ambient brightness, and Ruger says it gathers so much light that it’s usable even in surprisingly dark environments.
